简要介绍了我国C_4烃的资源量、利用现状与发展情况,并概述了其主要来源与组成。对C_4烃中用途较为广泛的组分丁二烯、正丁烯、异丁烯、正丁烷、异丁烷的分离方法及国内外主要利用技术进行了详细的阐述,并介绍了其中一些较为先进的工艺技术。针对目前国内外C_4烃利用所面临的问题,尤其是国内C_4烃利用所遇到的技术难题与发展瓶颈,结合我国的市场与国情,提出了一些针对性的建议与期望,并对我国C_4烃的未来发展方向进行了相应的展望。
This paper briefly introduces the resources of C 4 hydrocarbons in China, makes use of the status quo and development situation, and summarizes its main sources and compositions. The separation methods of butadiene, n-butene, isobutylene, n-butane and isobutane which are the most widely used C_4 hydrocarbons are described in detail, and some of the more advanced ones Technology. In view of the current problems in the utilization of C_4 hydrocarbons at home and abroad, especially the technical problems and bottlenecks encountered in the utilization of C_4 hydrocarbons in China, some suggestions and expectations are put forward in light of the market and national conditions in our country. The future direction of the development of the corresponding outlook.
