Aromatic and aliphatic production of catalytic pyrolysis of lignin using ZSM-5/Al-SBA-15 catalyst derived from high-calcium fly ash

In this work, lignin was utilized as biomass feedstocks to study the feasibility of fuels and chemical production, while fly ash was used for synthesizing ZSM-5 (FA-ZSM-5) and SBA-15 (FA-SBA-15) catalysts for upgrading pyrolysis products. The use of fly ash offers several benefits such as reducing t...

Among all catalysts, FA-ZSM-5/ FA-SBA-15 ratio of 1:2 showed the optimum dual catalyst ratio to enhance the highest yield of aliphatic and aromatic hydrocarbons of 15.1 and 21.4 % with the acceptable yield of phenolic compounds (34%).
