 Synergistic effects, gas evolution and ash interaction during isothermal steam co-gasification of biomass with high-sulfur petroleum cokeXin Yu, Dunxi Yu, Fangqi Liu, Jingkun Han, Jianqun Wu and Minghou Xu Energy, 2022, vol. 240, issue C Abstract: This work investigated the co-gasification behavior of rice straw (RS) and a high-sulfur petroleum coke (PC). An isothermal gasification experiment under a steam atmosphere was conducted on a self-designed thermogravimetry (TG) coupled with mass spectrometry (MS). The results indicate that the high sulfur content in PC seem to have no significant effect on co-gasification. RS showed obvious catalytic effect only after it was completely gasified into ash. Affected by the high concentration of steam, the main components of synthesis gas are H2 and CO2. The RS ash presents a violent melting state, and the lower RS addition ratio only shows a strong catalytic effect in the initial stage of the reaction. The high addition ratio makes the ash particles in the liquid phase contact and react well with the PC particles, and will not inhibit the gasification of the PC particles before the PC particles are completely wrapped.
