粉煤低温干馏现状及发展趋势

In this paper compares the coal carbonization process and coal liquefaction, coal gasification process in order to analyze the strengths and weaknesses of coal pyrolysis. This article briefly describes the status of domestic and international coal pyrolysis, the main process equipment of drying pulverized coal distillation and pyrolysis. Through analysis the physical and chemical properties of pyrolysis products and the factors that affect the pyrolysis products, context of the current demand conditions and cost-effectiveness of drying distillation products, set out the future development trend of pulverized coal pyrolysis. Coking coal, the lignite or high volatile coal reserves is rich in china, if can get the low temperature pyrolysis gas and oil recovery, it can make the comprehensive utilization of coal effectively.
