Biomass catalytic pyrolysis: process design and economic

The estimation of catalytic pyrolysis oil (CPO) production cost in a biomass catalytic pyrolysis (BCP) process is the objective of this study. Experiments carried out with a woody biomass (Beechwood) and a commercially available ZSM5 catalyst in a circulating fluid bed (CFB) reactor are the basis for the design of a commercial unit.

As mentioned earlier, slow pyrolysis is typically used to modify the solid material, minimizing the oil produced. Fast pyrolysis and ultra-fast (flash) pyrolysis maximize the gases and oil produced. Fast pyrolysis is a rapid thermal decomposition of carbonaceous materials in the absence of oxygen in moderate to high heating rates.

Pyrolysis of Torrefied Biomass - ScienceDirect

Pyrolysis of biomass is the thermal decomposition of organic materials in an oxygen-free environment at a temperature range of 300900°C.During the thermal decomposition process, hemicellulose, cellulose, and lignin undergo different reactions, leading to a three-stage reaction: removal of moisture, main decomposition, and the formation of bio-char .

Co-firing also eases the demand for coal. This reduces the amount of carbon dioxide and other greenhouse gases released by burning fossil fuels. Pyrolysis Pyrolysis is a related method of heating biomass. During pyrolysis, biomass is heated to 200° to 300° C (390° to 570° F) without the presence of oxygen.
