摘　　要：褐煤含挥发分高 ,适于转化利用。简单介绍了 1 50 t/ d平庄工业试验褐煤固体热载体低温干馏 (新法干馏 )工艺流程。讨论了干燥 ,混合 ,气固分离和灰熔温度。中国年轻煤多 ,有利于发展新法干馏技术。The lignite with high volatile matter is advantage of retorting using hot char as solid heat carrier. The pilot plant 150 t/d was briefly discribed, in which techniques on drying, mixing, separation of solid and gas and ash fusion were discussed. The new retorting technique would develop extensively in China, it is rich in lignite and subbituminous coal.

关 键 词：褐煤 低温干馏 热解 温和转化
