Electron-beam synthesis of fuel in the gas phase

Electron-beam synthesis of liquid fuel from gaseous alkanes was upgraded for formation of conventional and alternative fuel from biomass or pyrolysis oil. Bio-feedstock conversion algorithm includes two consecutive stages: (1) initial macromolecules' transformation to low-molecular-weight intermediates; (2) transformation of these intermediates to stable fuel in gaseous alkanes' atmosphere. Radicals originated from alkanes participate in alkylation/hydrogenation of biomass intermediates. Chemical fixation of gaseous alkanes is amplified in the presence of biomass derivatives due to suppression of gas regeneration reactions, higher molar mass of reagents and lower volatility of radiolytic intermediates.

► Direct biomass or bio-oil conversion to stable fuel in alkane atmosphere by electron-beam irradiation.
► Conversion algorithm includes two consecutive stages.
► Gas serves both for hydrogenation/alkylation and for inhibition of undesirable reactions.
► Chemical fixation of gaseous alkanes is amplified in the presence of biomass derivatives.
