Jingxi Anthracite has the common characters as other anthracites, such as without caking property, less content of volatile. Besides, it has some special features, for example, lower ash fusibility and worse thermal stability. Jinxi anthracite gasification character research has been conducted in the 600 mm ID moving bed gasifier. The result is shown that, the ash is easy to soften and melt into lump. The environment was destroyed and reduces the gas quality. While, if increasing the saturation temperature the operation situation in the gasifier can be improved. If increasing the layer of coal, the feed coal can be preheated fully in drying layer. Thus, heat shock to the anthracite may decrease and the effect of thermal explosion on the gasification process may also weaken.

The CO2 gasification reactivity test of coke that is taken from Huolinhe, Yima, Yanzhou, Pingshuo, Shenhua and Datong coal was conducted at 900～1050℃ in the thermobalance. Dynamic parameters of six coal coke samples were gained through experiment data treatment. The CO2 gasification reactivity of coal coke is contracted under different parameters.
