Pyrolysis Technology

Pyrolysis is one of the technologies available to convert biomass to an intermediate liquid product that can be refined to drop-in hydrocarbon biofuels, oxygenated fuel additives and petrochemical replacements. Pyrolysis is the heating of an organic material, such as biomass, in the absence of oxygen. Biomass pyrolysis is usually conducted at or above 500 °C, providing enough heat to deconstruct the strong bio-polymers mentioned above. Because no oxygen is present combustion does not occur, rather the biomass thermally decomposes into combustible gases and bio-char. Most of these combustible gases can be condensed into a combustible liquid, called pyrolysis oil (bio-oil), though there are some permanent gases (CO­2, CO, H2, light hydrocarbons), some of which can be combusted to provide the heat for the process. Thus, pyrolysis of biomass produces three products: one liquid, bio-oil, one solid, bio-char and one gaseous, syngas. The proportion of these products depends on several factors including the composition of the feedstock and process parameters.

Application

for used tires recycling

used tires recycling

Tire pyrolysis is a well-developed technology for used tires recycling. Pyrolysis process converts used tires to liquid fuel (45%), carbon black (30%), steel wire (15%) and syngas (10%).

Production Ratios
FUEL OIL 45%
carbon black 30%
steel wire 15%
Syngas 10%
For Waste Plastics Recycling

waste plastics recycling

Plastic types including HDPE, LDPE, PP, PS produce high ratio of liquid fuel oil, while PET and PVC doesn’t contribute to oil yield. The average oil yield from plastic wastes is 50%~75% based on conditions of raw material.

Production Ratios
FUEL OIL 60%
carbon black 30%
Syngas 10%
For oil sludge recycling

oil sludge recycling

It uses customized design of pyrolysis plant to process oil sludge. The oil recovery yield depends on the conditions of raw material, such as the content of impurities and water. Averagely the production ratio could be 60% of fuel oil, 30% of slag and 10% of syngas.

Production Ratios
FUEL OIL 60%
slag 30%
Syngas 10%

structure of pyrolysis plant

Based on its function, pyrolysis plant is composed of 6 main systems.

pyrolysis_structure CONDENSING SYSTEM PYROLYSIS REACTOR FEEDING SYSTEM EMISSION CONTROL SYSTEM DISCHARGING SYSTEM HEATING SYSTEM

Pyrolysis Reactor

Provides a high temperature and oxygen-free working condition for pyrolysis process.

  • Pyrolysis reactor is the part where pyrolysis reaction happens. The internal pyrolysis chamber is heated and the internal temperature goes up to more than 500℃. Therefore the internal pyrolysis reactor is manufactured by Q245R boiler plate with the thickness of 16mm to achieve long service life.

  • The internal reactor are rotating in production to let feedstocks get heated evenly. The rollers are placed under feeding port and oil gas outlet port which are external from heating area to bring perfect rotating balance and long service life.

  • The insulation cover provides good heat preservation effect to save fuel consumption.

  • On both ends of feeding port and oilgas outlet port, pressure gauge and safe valve are installed to ensure safe operation.

Condensing System

The pyrolysis gas (oil gas) is cooled down by condensing system and becomes liquid fuel oil after liquidation.

  • The oil yield is largely affected by cooling effect. While cooling effect is decided by three key points: cooling time, cooling area, cooling distance.

  • The cooling system is reasonably designed to fullfill the three key points and provides good cooling effect.

  • Easy operation and maintenance.

  • Non-condensable gas (combustible gas) is collected and routed to heating system as fuel supply. It saves fuel consumption and protect environment at the mean time.

Feeding System

Loads feedstocks into pyrolysis reactor with 50 ton hydraulic pressure.

  • Hydraulic feeder can load more feedstocks since it can compact feedstocks while feeding using its 50 ton hydraulic pressure.

  • Less feeding time and more feeding capacity than manual feeding.

  • No workers enter inside pyrolysis reactor to load feedstocks, thus operation is safe.

  • Short internal time to start next production batch. If it’s manually feeding, the pyrolysis reactor needs to fully cool down before labour can enter inside.

Heating System

By burning fuels heating system provides the heat required by pyrolysis process.

  • It can use pyrolysis oil and combustible gas produced from production. So the system can run with its own fuel supplies without extra cost.

  • Different types of burners are available based on customers’ requirements.

  • The heating system can be built either under ground or above ground.

Emission Control System

Purifies the flue gas to ensure clean air emission.

  • After purification by emission control system, the air emission is pollution-free.

  • Different types of de-dusters are available to achieve qualified emission standard according to customers’ requirement.

  • Easy operation and maintenance.

Discharging System

Discharges carbon black and steel wire from pyrolysis reactor when the production is finished.

  • Carbon black is discharged in a sealed condition to avoid pollution.

  • The condenser cover provides cooling function when carbon black is discharged.

  • Easy storage and packing. Easy operation and maintenance.
