摘要:

详细阐述了目前国内外主要煤炭地下气化技术的技术类型及发展现状,对煤炭地下气化的产业做了综合分析。与传统的煤炭开采利用技术相比,UCG在环境保护效益、煤炭资源利用率、经济性及安全性等方面具有明显优势,同时也存在诸如气化过程难以控制、地下水资源污染、产品气组分和热值不稳定等方面的不足。综合来看,目前UCG技术的优越性及应用前景是广阔的,具有良好的经济效益和一定的环境效益,是我国解决当前能源安全和环境污染的有效途径。

Abstract:

This paper details the advances and technical category of UCG, and analyzes comprehensively the UCG industry. Compared with the traditional coal mining, UCG possesses outstanding advantages in environmental protection, coal utilization efficiency, and economy and safety, but disadvantageous in difficultlycontrolled gasification, underground water pollution, unstable gas components and heat values. In general, UCG is of prospects, economic and environmental profits in application, it is an effective way to ensure China's energy security and environmental protection.

Key words: UCG, advances of technology, industry development
