“…With the presence of CaO in the BFS, CO 2 in the production syngas was absorbed and converted to CaCO 3 , thus shifted the water gas shift reaction and enhanced the H 2 concentration [28,29]. In addition, metal oxides could prevent the formation of stable chemical structures in hydrocarbons, speed up the degradation of hydrocarbons, weaken the CeC bond and thereby reduce the activation energy of the gasification reaction [30,31].…”

a b s t r a c tIn this study, the isothermal tests for steam gasification of Dezhou (DZ) low-rank coal with molten blast furnace slag (BFS) were performed in a lab-scale continuous gasification system, to investigate the status of gasification and syngas production. The results showed that molten BFS provided the heat needed for gasification reaction to ensure gasification is successful. The carbon conversion efficiency (CE), cold gasification efficiency (CGE) and percentage of combustible gas were higher than 85%, 100% and 87%, respectively. Meanwhile, thermo-gravimetric kinetic experiments were conducted to obtain the role of BFS in low-rank coal gasification. The study found that carbon conversion at a certain time was significantly enhanced with BFS as heat carrier. The reactivity index of coal was also improved under this condition. The reactivity index of coal with steam to coal (S/C) ratio of 1:2 was approximately 1.98 times higher than that with S/C ratio of 1:0 at 1673 K. The most probable kinetic mechanism model of DZ lowrank coal turned from D 2 model to A 2 model. Not only was BFS the heat carrier, but also it was the active catalyst in low-rank coal gasification. Eventually, the catalytic mechanism of coal gasification using BFS as heat carrier was schematically proposed.

“…The results were highly comparable with conclusions obtained by Wang [46] and Tursun [47] in previous studies. In addition, the metal oxides in the BF slag prevented the formation of stable chemical structures in hydrocarbons, speed up the degradation of hydrocarbons, and accelerated the CH 4 decomposition at this temperature [48,49].…”
