煤炭气化技术发展简析

Prospect for the Development of the Coal Gasification Technology

由于煤气化在高效、清洁利用煤炭能源方面有重要作用,国外近20年来煤气化能力得到了强劲的发展,我国煤气化在化工原料气、工业以至民用燃料气等方面也一直占有重要地位。但我国的洁净煤技术总体上还处于起步阶段,煤炭气化工艺的发展还要经历长期的发展过程。

The paper discusses the coal gasification technology from three aspects . a fixed bed with the lump coal as a raw material , a fluid bed with the bump coal as a raw material and an airflow bed with a fine coal as a raw material .
