Work of a pyrolysis plant

Pyrolysis is the thermal decomposition of a material in the absence of oxygen. Depending on the process, valuable raw materials such as pyrolysis charcoal, pyrolysis oil and gas are produced. A compact pyrolysis plant is designed for the thermochemical processing and utilization of biomass and other organic polymeric wastes to produce liquid and organic products as well as fine char.

The heart of each plant is the reactor. Here, heat is used to thermally crack the dry feedstock, excluding oxygen. At the microscopic level, organic compounds are split, and large molecules are broken down into smaller ones without combustion due to the exclusion of air. Far less CO₂ and energy is released from the feedstock, which leads to new energy-rich reaction products. A vapor-gas mixture and fine coke is produced. In the following step, the mixture is separated from the charring dust. During a cooling process, the condensation of the mixture separates the liquid pyrolysis products (bio-oil) from the flammable gases.

With pyrolysis it is possible to process various types of feedstock to produce energy-rich products, that can be further used.

These products are:

1.       Coke:

The solid pyrolysis products depend on the input material and the pyrolysis process. This fine coke and char are excellent for briquetting, energy use, as sorbents, as well as for usage in agriculture

2.       Pyrolysis Oil:

The liquid pyrolysis products are non-polar and can be used as alternative fuel or further refined to produce biodiesel fuel (depending on the input material).

3.       Pyrolysis Gas:

The resulting non-condensable pyrolysis gas is mostly consumed by the pyrolysis plant to generate heat energy for the process to pyrolyse.
