低碳经济下煤热解综合利用技术的应用和发展
Application and Development of Pyrolysis Technology in Low-Carbon Economy
摘要
Abstract
The efficient, clean and low carbon utilization is the leading direction of research and develop-ment of coal utilization technology. In China, the low rank coal, represented by lignite and subbituminous coal, is dominating in coal resources, accounting for more than 55%. Low rank coal is characterized with lower coalifica-tion degree, higher volatile matter and moisture content, which lead to low efficiency in direct combustion and gasification process. Therefore, a staged conversion technology based on coal pyrolysis, and the pyrolysis tech-nology with the features of mild conditions, simple process, wider applicability of coal, higher energy efficiency, lower water consumption, especially pyrolysis bridged hybrid power generation technology is proposed as a promising trend in research field. The process takes full advantage of coal composition characteristic to extract gas, liquid fuel, chemicals, and combined hybrid power generation. This technology can realize the improvements in energy efficiency, coal-fired efficiency, power generation efficiency, and the reduction of coal consumption, by upgrading processing, clean coal-fired of industrial boilers, integrating highly efficient steam–gas turbine com-bined cycle power generation technology. It aims to enhance coal comprehensive utilization efficiency, decrease pollutant and CO2 emission, and in the end promote the development of science and technology of high efficient low-carbon utilization of low rank coal.关键词
