摘要：

目前我国煤成气的勘探工作已经开始,前景令人鼓舞。由于煤成气资源评价工作的需要,我们进行了褐煤煤化作用的模拟试验。

Abstract:

Simulation experiment of coalification is carried out by the authors with Tertiary brown coal samples collected from Huangxian County,Shandong Province and Xindian County,Yunnan Province.In the end of different coalification stages,the average accumulative values of generated gaseous hydrocarbon corres-poding to each ton of residual coal are as follows:20m3 in fat and gas coal stages(Rm=0.95%),105m3 in lean coal stage(Rm=2.0%)and 398m3 in an-thracite stage(Rm=4.0%).As the coalification goes on,the δ13C of methane and the content of CO increase continuously,but CO2 decreases instead.
