Transportation fuels from biomass fast pyrolysis, catalytic hydrodeoxygenation, and catalytic fast hydropyrolysis

“…Similar results have also been obtained by the authors of this review, as we have recently performed catalytic fast hydropyrolysis of beech wood in a fluid bed reactor containing a sulfided CoMo/MgAl2O4 catalyst with and without a downstream fixed bed reactor containing a sulfided NiMo/Al2O3 catalyst[370]. At varying pressures of 16-36 bar and temperatures of 365-510 °C, the yield of condensed and condensable C4+ organics was 17-22wt% daf.…”

Biomass pyrolysis: A review of the process development and challenges from initial researches up to the commercialisation stage

“…The pressure increase enhanced the bio-oil yield while the CO and CO 2 yields decreased. They could conclude that catalytic pyrolysis could be a potential process to produce the fuels could replace the fossil fuels [349] . Zhang et al studied the effects of metal oxide catalyst including Al 2 O 3 , SiO 2 , ZnO, K 2 O, MgO, CaO, La 2 O 3 on the pyrolysis of poplar wood, cellulose and lignin.…”

The Influence of Active Phase Loading on the Hydrodeoxygenation (HDO) of Ethylene Glycol over Promoted MoS2/MgAl2O4 Catalysts

“…Catalytic hydropyrolysis is an efficient process for the direct production of diesel and gasoline type fuels from solid lignocellulosic biomass such as wood and agricultural residues [1][2][3][4][5]. Such fuels are necessary to reach the goal of becoming independent of fossil fuels, especially in the heavy duty and aviation sector, which are not immediately moving towards electrification.…”
