Fast pyrolysis can directly produce a liquid fuel from biomass which can be readily stored or transported. Biomass is a mixture of hemicellulose, cellulose, lignin and minor amounts of other organics which each pyrolyse or degrade at different rates and by different mechanisms and pathways. Ex situ catalytic fast pyrolysis of lignocellulosic biomass to hydrocarbon fuels. Bioenergy is now accepted as having the potential to provide the major part of the projected renewable energy provisions of the future. Controlling deoxygenation pathways in catalytic fast.

An overview of fast pyrolysis of biomass sciencedirect. Pdf catalytic fast pyrolysis of biomass researchgate. For the hydrogenproduction scenario, 38% of the biooil is reformed to produce 1,500 kghour of hydrogen. Fast pyrolysis is one of the three main thermal routes, with gasification and combustion, to providing a useful and valuable biofuel.
Biomass must first be dried and ground to biooil yield for a 2,000 mtday corn stover pyrolysis plant is 104 million gallons 394 million liters per year, representing 72% yield by weight of the dry biomass input with 15% water content. It occurs in a hightemperature range of 300700c at a faster heating rate of 10200cs, with a short solid resistance time of 0. Biomass fast pyrolysis is of rapidly growing interest in europe as it is perceived to offer significant logistical and hence economic advantages over other thermal conversion processes. Tan,1 joshua schaidle,1 david humbird, 2 huamin wang, 3 damon hartley, 4 david thompson,4 and hao cai5. When the sawdust was pyrolyzed at 460 c in pyrolysis gas and the condenser with spraying, a maximum biooil yield of 71. Fast pyrolysis product yields are typically 5070% biooil, 1030% biochar, and 1520% syngas by mass. Advances in science and technology edited by robert c. Fast pyrolysis of biomass is one of the most promising technologies for converting biomass to liquid fuels. Sawdust pyrolyzed in pyrolysis gas increased the biooil yield and the concentrations of h.
