In-Situ Catalytic Upgrading Of Biomass Pyrolysis Vapor: Co-Feeding With Methanol In A Multi-Zone Fixed Bed Reactor

Faculty of Engineering University of Malaya

The in-situ catalytic upgrading of the biomass pyrolysis vapor and its mixture with methanol were conducted in a fixed bed multi-zone reactor. The steps were comprised; thermally converting the biomass in the pyrolysis reactor, passing its vapor in contact with the HZSM-5 zeolite catalyst in the presence of methanol vapor, and transformation of the resulting upgraded pyrolysis vapor into the liquid product. The biomass pyrolysis and catalytic pyrolysis vapor upgrading were performed at 500 degrees C. The highly valuable chemicals production was a function of the hydrogen to carbon effective ratio (H/C-eff) of the feed. This ratio was regulated by …
