摘　　要：对煤进行预处理是提高煤热解焦油产率的途径之一。研究了采用甲醇蒸气对红柳林烟煤进行预处理,再进行热解,以提高热解焦油产率的可能性。探讨了预处理气氛、温度、甲醇蒸气流量和时间对红柳林烟煤热解产物分布的影响规律。Pretreatment of coal is one of the methods to improve the tar yield of coal pyrolysis. The possibility of improving the tar yield of Hongliulin coal pyrolysis by pretreatment the coal with methanol vapor was studied, and the effect of pretreatment parameters as atmosphere, temperature, flow rate and time on the yields of coal pyrolysis products were investigated.
