The catalytic gasification performance of Buliangou coal using Ca(OH)₂ as catalyst was investigated at 3.5 MPa and 700-800℃ in a pressurized fixed bed. The effect of gasification temperature, Ca(OH)₂ loading and loading method on coal steam gasification and methanation reaction were examined. The results show that Ca(OH)₂ can enhance the reactivity of char gasification and the formation of CH₄. Increasing temperature and Ca(OH)₂ loading can heighten the carbon conversion, but Ca(OH)₂ loading possesses a saturation point. The gasification reactivity is affected by loading method which determines the Ca(OH)₂ dispersion. The coal char loaded with Ca(OH)₂ shows a great catalytic activity on methanation reaction and the CH₄ content in the product gas increases with the increase of methanation temperature and catalyst loading. The analysis result of coal surface function groups by FT-IR reveals the dispersion mechanism of Ca(OH)₂ into the matrix of coal through ion exchange and diffusion, which is a key factor to improve coal char gasification reactivity.
