摘要：
A gas-pressurized (GP) torrefaction method, proposed in our resent work, can significantly promote the up-grading and oxygen removal of biomass wastes, compared to the traditional torrefaction (AP). However, the mechanism of the GP torrefaction process is not clear. In present work, semi-closed (SC) torrefaction, GP tor-refaction, and AP torrefaction were conducted to reveal the roles of pressure and secondary reactions during GP torrefaction quantitatively. The results showed that the pressure significantly promoted the upgrading of bio-mass during GP torrefaction at 200 degrees C. The contribution of pressure on the oxygen removal of GP torrefaction at 200 degrees C was 63.87%. At relatively high temperature of around 250 degrees C, the promotions were caused by the synergistic effect of pressure and secondary reactions. The contribution of secondary reactions on the oxygen removal was 53.99%. Thus, the process of the GP torrefaction of biomass wastes was preliminarily understood.
