记者从3月23~24日召开的第四届国际轻烃综合利用大会上了解到,在C_4资源的综合利用方面,我国目前出现了一种“重烯烃,轻烷烃”的趋势。国内企业特别是民营企业对C_4烯烃的大部分都能做到精细化利用,例如正丁烯氧化脱氢制丁二烯、歧化制丙烯等,但C_4烷烃的开发利用率却一直 Reporter from March 23 to 24 held the Fourth International Light Hydrocarbon Comprehensive Utilization Conference learned that in the comprehensive utilization of C_4 resources, our country now appears a “heavy olefins, light alkanes ” trend. Domestic enterprises, especially private-owned enterprises, can make fine use of most of C4 olefins, for example, the oxidation and dehydrogenation of n-butene to butadiene and the disproportionation of propylene, etc., but the development and utilization of C_4 alkanes have been
