摘要: 我国褐煤资源丰富,褐煤含水分高,灰分高,热值低,不宜长途运输。褐煤多联产技术集褐煤预处理、气化、化工合成、发电、供热等工艺技术于一体,解决了褐煤的运输和燃烧问题,并且对其综合利用,开发出了下游工业产品,具有良好的经济效益和应用前景。本文介绍了几种褐煤干燥(成型)工艺及在国内的应用现状,并介绍了褐煤预处理(即干燥)后的综合利用工艺,如合成氨、合成甲醇、制氢等。

Abstract: China is rich in lignite which is not suitable for long distance transportation for its high moisture and ash level and low calorific value. “Lignite co-production” technology includes lignite pre-treatment,gasification,chemical synthesis,power generation and heat supply etc.,which can solve the problems of transportation and burning for lignite and also can provide integrated utilization with downstream industrial products. Such a technology shows good economical efficiency and promising future. This paper provides a brief introduction for domestic application of lignite drying(shaping)technology and lignite integrated utilization technology after pre-treatment(drying),such as the production of ammonia,methanol and hydrogen,etc.
