【Abstract】 The resource amount,utilization status and development situation of C₄ hydrocarbons in China are briefly reviewed,and the main sources and related compositions of C₄ hydrocarbons are outlined. The separation methods and main utilization technologies at home and abroad for the C₄ components with wider applications such as butadiene,nbutylene,i-butylene,n-butane and i-butane are discussed in details,some advanced processes and technologies of which are introduced. Given the problems met in the utilization of C₄ hydrocarbon currently around the world,especially the technical difficulties and developing bottlenecks faced in China’s utilization of C₄ hydrocarbon,together with China’s market and special situation,some related suggestions and expectations are proposed. In addition,the future development tendencies of C₄ hydrocarbon in China are prospected correspondingly.更多还原
