Catalytic reforming of palm kernel shell pyrolysis volatile matter for single-ring aromatic compounds production
Catalytic reforming of palm kernel shell(PKS)pyrolysis volatile matter was studied using char(Char)and activated carbon(AC)as catalysts under microwave-assisted heating.The impacts of different carbon-based catalysts on the composition of products were studied.The possible reaction pathways during catalytic reforming of PKS pyrolysis volatile matter under microwave-assisted heating were also investigated.During catalytic reforming of pyrolysis volatile matter,the catalyst promoted the yield of gas product,which led to the decrease of bio-oil yield.Compared with the Char,AC not only has higher catalytic activity to facilitate the conversion of bio-oil to gas,but also exhibited better selectivity for the formation of single-ring aromatic compounds(especially phenol)in bio-oil.Using the AC catalyst,the concentrations of the single-ring aromatic compounds reached 84.25%.The catalyst mainly promoted the secondary reactions such as demethoxylation reaction and dehydrocarbylation reaction.
