摘要：The current study aims to investigate the effects of agricultural waste-derived activated carbon catalyst on the jet-fuel range hydrocarbons distribution from raw biomass pyrolysis under the hydrogen donor condition provided by a solid waste. Ex-situ catalytic fast co-pyrolysis of lignin with and without soapstock was carried out using the corn stover-derived activated carbon catalyst in a facile fixed bed reactor. Results showed that the soapstock, as the hydrogen donor, exhibited a positive synergistic effect with lignin on enhancing the production of valuable aromatics in the obtained bio-oil. Additionally, biomass-derived activated carbon catalyst has the robust catalytic ability to convert pyrolysis vapors into high-density jet fuel-ranged aromatic hydrocarbons rather than phenols with the assistance of soapstock solid waste. Results indicated that the proportions of jet-fuel range aromatics increased monotonically with elevating pyrolytic temperatures from 400 to 550 degrees C, and the optimal lignin/soapstock ratio was 1:2 with regarding the yield of attained bio-oils. The maximum proportion of jet-fuel ranged aromatics (87.8%) and H-2 concentration (76.4 vol%) could be achieved with the pyrolytic temperature, lignin/soapstock ratio, and catalyst/feedstock ratio of 550 degrees C, 2:1, and 1:1, respectively. The current study may provide a novel route of converting solid wastes into value-added jet fuels and hydrogen-enriched fuel gases, which will advance the utilization of renewable biomass.
