The gaseous products of pyrolysis include H2, CH4, H2O, CO2 (C3H8), CO, and C2H6. These gases are released during the pyrolysis process, which involves the thermal decomposition of organic matter in the absence of oxygen. The gas products are mainly comprised of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), hydrogen (H2), and other low carbon number hydrocarbons. The composition of the gaseous products can vary depending on the temperature and conditions of the pyrolysis process. At higher temperatures, H2 and CXHY gases are also produced. The yield of gaseous products can vary under different process conditions, but typically ranges from 12 wt% to 15 wt%. Pyrolysis gases can be classified into incombustible gases (H2O and CO2), combustible gases (CO and CH4), and N-containing gases (NH3 and HCN). The formation of CO2 mainly originates from decomposition reactions of carbonyl and carboxyl groups, while the formation of CO mainly results from breaking of C-O-C and C = O bonds. H2 mainly results from breaking of C-H groups and aromatics. CO and CO2 are dominant gaseous products at low temperatures, while CH4 is a dominant product at high temperatures due to lignin depolarization reactions.
