Abstract: Pyrolysis of Huolinhe lignite with solid heat carrier was carried out in a moving bed reactor with the capacity of 10kg/h. The solid heat carrier used in the experiment was the circulating ash from a 75t/h CFB boiler. The effects of pyrolysis temperature, residence time and coal particle size on the yields and composition of products were studied. It is found that the gas yield increases with the increasing pyrolysis temperature. The yield of tar reaches a maximum of 4.94% at 520℃. The heating value of pyrolysis gas is from 19.80MJ/m³ to 23.20MJ/m³. Some useful compounds, such as BTX and PCX, could be obtained from pyrolysis tar and the contents of them are much higher than those from a bituminous pyrolysis tar. Moreover, the pyrolysis char exhibits good combustion characteristic. The sulfur content of pyrolysis char is notably lower than that in raw coal, which benefits to reduce the desulphurization burden of the CFB boiler.
