Conversion of sugar diacetyls to bio-hydrocarbons by the catalytic cracking in a fixed bed with fresh and deactivated Beta zeolite

The conversion of biomass into fuel under typical refinery conditions is a promising solution to decrease carbon footprint. Herein we convert representative compound new bio-petroleum, DX (1,2:3,5-di-O-isopropylidene-α-D-xylofuranose) mixture with n-hexane. Firstly fresh zeolites (Beta, ZSM-5 and USY) were explored. Beta zeolite showed high performance in converting hydrocarbons. Thus it was further modified by hydrothermal deactivation. This treatment reduced the acid site density Beta, resulting an improvement aromatics, reducing gas 2-fold coke 1-fold, only leaving small amount oxygenates liquid fraction test 20% DX.
