Abstract
This study investigated the effects of torrefaction with Mg(OH)2 on the properties of bio-oil formed from the microwave-assisted catalytic fast co-pyrolysis of straw stalk and soapstock. The effects of torrefaction temperature and residence time on the yield and composition of bio-oil were discussed. Results showed that the torrefaction temperature and residence time remarkably influenced the yield and composition of bio-oil. With the increase in temperature and time, the bio-oil yield and the proportion of oxygen-containing compounds decreased, while the proportion of aromatic compounds increased. When the feedstocks were subject to torrefaction reaction for 20 min at 260 °C, the proportion of oxygen-containing compounds decreased from 29.89% to 16.49%. Meanwhile, Mg(OH)2 could render the deoxidization function of torrefaction process increasingly noticeable. The proportion of the oxygen-containing compounds reached a minimum (14.41%), when the biomass-to-Mg(OH)2 ratio was 1:1.
