一种新的洁净能源

摘要

Gas generated from coal gasification taking place underground is a new kind of energy source which possesses the advantages such as high utilization of coal resource, less environmental pollution. At present, the technology of producing such gas is not perfect yet, and its investment is higher than that of other technologies of energy producing. Besides, there is lack of funds to improve the technology. But in the view of the trend of using clean energy and protecting the environment, the technology will achieve great development and be used widely in the 21st century.%煤炭地下气化产生的煤气是一种新的洁净能源。研究和开发这种新能源，不仅能提高煤炭利用率，而且能减少环境污染。该项技术本身尚不完善，目前也还存在投入提高该技术的资金困难，与其它化石燃料相比成本偏高等问题。从使用洁净能源和环境保护的角度，这一技术将是21世纪获得重大发展的洁净能源技术。
