On the effect of hydrothermal pretreatment of biomass and catalytic conversion mechanism in pyrolysis process with a review of flash pyrolysis of lignocellulosic biomass using effective catalyst

The inception of biofuels have induced the need for technologies such as pyrolysis, gasification and related. With flash pyrolysis (non-catalytic) and the obtained product yields in bio-oil are discussed with regard to the effect of hydrothermal pretreatment of biomass or the effect of catalyst’s type (zeolitic or mesoporous). A review of catalytic upgrading of pyrolysis vapors of lignocellulosic biomass (beech wood) in its parent state or after being subjected to hydrothermal pretreatment is taken up in the concluding part.
