Two technology roads are often mentioned in the same breath whenever a waste-to-fuel project is discussed: gasification → syngas → Fischer-Tropsch → finished fuels, and pyrolysis → pyrolysis oil → distillation / refining. This article stands on its own. It compares the two routes only as far as the equipment list is concerned, then gives a complete buyer's guide to the pyrolysis line. If your feedstock is waste tyres, waste plastics or oily sludge, the purchasing decision becomes concrete: you are either buying a gasifier, a gas-cleaning island, an F-T reactor and a hydrocracking train, or you are buying a pyrolysis plant, a distillation plant and a refining plant with their auxiliary machines.
1. The equipment lists are not interchangeable
|

Gasification → Syngas → F-T |
Pyrolysis → Pyrolysis Oil |
|
Feed preparation |
Drying, torrefaction, size reduction, RDF pelletising |
Tire Cutting Machine, Steel Wire Winch, Steel Wire Bundling Machine, Grabbing Loader, hydraulic feeder |
|
Primary conversion |
Entrained-flow / fluidised-bed gasifier (700–1,400 °C) |
Batch Pyrolysis Plant or Continuous Pyrolysis Plant (350–550 °C, oxygen-free) |
|
Gas handling |
Cyclones, tar cracker, scrubber, amine / acid-gas removal, water-gas shift |
Gas Storage Bag, sync-gas recycling loop, burner, Gas Storage Bag buffering |

Nothing in the left column is a scaled-up version of the right column. A continuous tyre pyrolysis plant cannot be upgraded into a gasifier, and an F-T reactor cannot process whole tyres. That is the practical meaning of "two different routes".
2. Batch Pyrolysis Plant family
The Batch Pyrolysis Plant is the entry point for most recycling businesses. A Batch Tyre Pyrolysis Plant loads shredded or whole tyres, seals the reactor, heats it, condenses the vapour, cools down, then discharges recovered carbon black and steel wire. A Batch Plastic Pyrolysis Plant does the same for PE / PP / PS feed, and an Oil Shale Pyrolysis Plant or an oil-sludge variant handles mineral-loaded material. A batch waste tyre pyrolysis reactor, batch rubber pyrolysis treatment system, batch pyrolysis plant with sync gas recycling, batch tyre oil pyrolysis plant and batch pyrolysis plant for mixed plastic and tyre waste are all configurations of this family.
Buyers searching this category use a very wide vocabulary. A tire pyrolysis machine, tyre pyrolysis machine, tire pyrolysis equipment, tyre pyrolysis plant, tyre recycling pyrolysis plant, waste tyre plant, waste tyre pyrolysis machine, waste tire pyrolysis machine, waste rubber pyrolysis plant, rubber pyrolysis machine, rubber pyrolysis plant and tyre pyrolysis for fuel oil and carbon black production are all describing the same batch line. So are tyre to diesel recycling plant (strictly, it produces fuel oil that is later distilled), small tyre recycling plant, small scale tyre recycling plant, small scale plastic pyrolysis plant, small pyrolysis plant, small pyrolysis machine, mini pyrolysis plant, 1 ton plastic pyrolysis plant, pyrolysis pilot plant, diy pyrolysis plant, second hand tyre pyrolysis plant, mobile pyrolysis plant, skid mounted pyrolysis plant, msw pyrolysis plant, coal pyrolysis plant, commercial pyrolysis plant, waste pyrolysis plant and pyrolysis factory.
Size and duty decide the configuration. A portable small pyrolysis machine, low-footprint small pyrolysis machine, economical small pyrolysis machine and energy-saving small pyrolysis machine suit a first plant or a pilot. A large-tonnage plastic pyrolysis plant, high-capacity tire pyrolysis machine, large-output tire pyrolysis machine, industrial plastic to fuel converter, heavy-construction waste pyrolysis plant and large-scale msw pyrolysis plant suit an industrial operator. High oil yield batch plastic pyrolysis plant, anti-clogging batch reactor for plastic to oil, high-conversion plastic pyrolysis machine, wear-resistant plastic pyrolysis plant and corrosion-resistant pyrolysis device for waste plastic describe the engineering refinements that separate a reliable machine from a cheap one.
3. Continuous Pyrolysis Plant family
When throughput justifies it, a Continuous Pyrolysis Plant replaces the batch cycle with 24-hour feeding and discharging. Our catalogue covers Continuous Tyre Pyrolysis Plant, Continuous Plastic Pyrolysis Plant, Continuous Oil Sludge Pyrolysis Plant and Continuous Rubber Pyrolysis Plant - in buyer language, a continuous plastic pyrolysis plant, continuous pyrolysis machine, continuous tyre pyrolysis plant, continuous waste tyre pyrolysis plant, fully automatic pyrolysis plant or fully automatic tyre pyrolysis plant.
A continuous line adds sealed screw feeding, continuous solids discharge, an oxygen-free transfer system and PLC control of the temperature profile. That is why fully automatic pyrolysis plant and continuous pyrolysis are high-intent phrases: the buyer is no longer comparing reactors, they are comparing labour cost, uptime and safety interlocks. The fully continuous unit in our catalogue runs around the clock with automatic feeding, while the semi-continuous unit bridges the two families. Indicative capacity bands run from pilot scale to 20–50 t/d, with oil yield in the 40–45 % range for tyres.
4. Oil Processing Plant - distillation
Raw pyrolysis oil is a broad boiling-range condensate. The Distillation Plant family separates it. Core product names in our catalogue include Pyrolysis Oil Distillation Plant, Used Oil Recycling Plant, waste oil distillation plant, used oil distillation plant, distillation column plant, crude oil distillation plant, chemical distillation plant, industrial distillation plant, vacuum distillation plant, double distillation plant, mini distillation plant, small distillation plant, pilot scale distillation column, pilot distillation column, distillation pilot plant and glycerine distillation plant.
Phrases buyers actually type include pyrolysis oil distillation plant, distillation plant for sale, distillation plant working, industrial distillation plant, small distillation plant, vacuum distillation plant, steam distillation plant, continuous distillation system, multi column distillation plant, used oil distillation plant, waste oil distillation plant and pilot distillation column. A distillation column plant on a pyrolysis line works at atmospheric or reduced pressure; vacuum cuts the heavy end without thermal cracking, which protects the colour and stability of the diesel cut. Our horizontal distillation units are rated at roughly 3–10 t per 24 h, with an indicative oil recovery of 85–95 %, 15–25 kW installed power and circulating-water cooling.
This is also where used oil recycling plant and oil regeneration equipment projects overlap with pyrolysis: used oil refinery plant, waste engine oil re-refining, black oil refinery plant, lubricant oil refinery plant and recycled base oil production all use the same fractionation hardware with a different pre-treatment.
5. Refining Plant - the finishing step
Distillation separates; refining improves. A Pyrolysis Oil Refining Plant, Used Oil Refining Plant or Crude Oil Refining Plant removes sulphur, olefins, colour bodies and particulates so the product can move from industrial fuel oil to a higher-value diesel blendstock. The buyer vocabulary here is broad: waste oil refinery plant, used oil refinery plant, pyrolysis oil refinery, used oil re-refining plant, mini refinery plant, small scale oil refinery plant, small crude oil refinery plant, mini petroleum refinery plant, petroleum refinery plant, petrochemical refinery plant, oil refinery and petrochemical plant, crude oil processing plant, physical refining plant, mini edible oil refinery plant, small scale edible oil refinery, palm oil refinery plant, cooking oil refinery plant, rice bran oil refinery plant and sunflower oil refinery plant.
A note for buyers: the edible-oil and petrochemical phrases above describe the same unit-operation family, not the same process guarantee. A pyrolysis oil refinery is specified for hydrocarbon feed with sulphur and olefin content; a vegetable-oil line is not. When you request a quotation, name the feedstock - this is the single most common cause of a mis-specified refining package.
6. Pyrolysis Plant Auxiliary Equipment
A complete line is mostly auxiliary machines. Our catalogue groups them as:
• Feeding: hydraulic feeder, Grabbing Loader, auto-loaders for 1,200 mm and smaller tyres.
• Pre-processing: Tire Cutting Machine, whole-tyre crusher, Steel Wire Winch and Steel Wire Bundling Machine.
• Gas handling: Gas Storage Bag, sync-gas recycling and purification, sealed flare for surplus gas.
• Solids: carbon black granule machine, carbon black grinding / conveying, enclosed discharge to avoid dust.
• Emissions: waste-water and waste-gas treatment skids, DCS / PLC control cabinet.
These are the machines that decide whether a plant passes an environmental audit. A low-emission plastic pyrolysis plant, smokeless tyre pyrolysis device, eco-friendly tyre diesel plant, eco-efficient mini pyrolysis plant, low-consumption small pyrolysis machine, energy-saving mobile pyrolysis plant or anti-corrosion coal pyrolysis device is not a different reactor - it is a reactor plus the right auxiliary package.

8. Buyer FAQ
Do I need a continuous plant or a batch plant? Batch wins on CAPEX and feed flexibility; continuous pyrolysis machine lines win on labour, steady product quality and 24-hour throughput. Fully automatic pyrolysis plant searches usually come from buyers who have already decided on continuous operation.
Can I add distillation later? Yes. A pyrolysis plant for waste plastic or a waste tire pyrolysis machine can be commissioned with a simple condensation set, then extended with a pyrolysis oil distillation plant, vacuum distillation plant and pyrolysis oil refining plant when the offtake contract justifies it.
What does "tyre to diesel" actually mean? A tyre to diesel recycling plant produces pyrolysis oil first; the diesel-range cut appears only after distillation and desulphurisation. Sellers who skip that step are describing fuel oil, not road diesel.
Which auxiliary machines are non-negotiable? Sealed feeding, Gas Storage Bag / sync-gas recycling, enclosed carbon-black discharge and gas treatment. Skipping them is what gives second hand tyre pyrolysis plant purchases a bad reputation.
Can one supplier scope the whole line? Yes - Aotewei (Shangqiu Aotewei Environmental Protection Equipment Co., Ltd.) supplies Pyrolysis Plant, Oil Processing Plant and Pyrolysis Plant Auxiliary Equipment as one integrated package, including model selection, layout, installation supervision and commissioning.
9. Start from the route, then pick the machines
If your project is a gasification → syngas → Fischer-Tropsch scheme, you need a different vendor list entirely. If it is a pyrolysis → pyrolysis oil → distillation / refining project with waste tyres, waste plastics or oily sludge as feed, the equipment catalogue above is your scope. Send us your feedstock, target tonnage and target product, and we will map it to the right batch pyrolysis reactor or continuous tyre pyrolysis plant, distillation column plant and pyrolysis oil refinery configuration.
Why One Integrated Aotewei Line Outperforms a Multi-Vendor Assembly
A gasification + F-T complex is by definition a multi-vendor project: the gasifier, gas-cleaning island, synthesis loop and hydrocracker each come from a different specialist, with interfaces nobody owns when something goes wrong. A pyrolysis line can be - and in our view should be - a single-supplier scope. Aotewei covers feeding, pyrolysis, distillation, refining, carbon black handling, gas recovery and emission control, plus the DCS / PLC cabinet, under one model list and one commissioning plan.
• One model ladder: Batch Tyre Pyrolysis Plant, Continuous Plastic Pyrolysis Plant and Continuous Oil Sludge Pyrolysis Plant share the same auxiliary platform, so a first plant can be expanded without replacing the front end.
• One utilities package: Gas Storage Bag, sync-gas recycling and purification, and a sealed flare mean the non-condensable gas heats the reactor instead of being bought in as fuel.
• One compliance package: enclosed carbon-black discharge, waste-water and waste-gas treatment skids, and a low-emission plastic pyrolysis plant configuration are what get a project through an environmental audit.
• One spares and service scope: 12-month standard spare parts, layout drawings, installation supervision and commissioning come from the same team that built the reactor.
The catalogue numbers make the operating case concrete: 40–45 % oil yield from tyres, 85–95 % recovery in the distillation column plant, 3–10 t per 24 h per horizontal distillation unit, 15–25 kW installed power. A skid mounted pyrolysis plant can be prefabricated and shipped; a fully automatic pyrolysis plant then cuts the operating crew to a minimum. Neither option exists in a gasification + F-T scheme at this scale - which is the practical reason buyers of tonne-per-day projects keep choosing a continuous tyre pyrolysis plant or a mobile pyrolysis plant instead.
Tell us your feedstock, target tonnage and target product, and we will configure the complete line - from the hydraulic feeder and Tire Cutting Machine to the pyrolysis oil distillation plant and pyrolysis oil refinery - not just a reactor.
Data note: models, capacities and oil parameters are indicative values from the Aotewei product catalogue and vary with feedstock and configuration.
