煤制烯烃副产混合碳五的综合利用探讨

Discussion on Comprehensive Utilization of C5 Fraction from Coal to Olefins Process

煤制烯烃技术是替代石油生产低烯烃的新型工艺路线，混合碳五是煤制烯烃重要的副产品，和石油化工副产混合碳五既有相似之处也存在差异，本文借鉴石油化工副产碳五馏分的综合利用技术，同时针对煤基甲醇制烯烃副产混合碳五馏分的特点，就甲醇制烯烃副产混合碳五馏分的综合利用进行探讨。指出了甲醇制烯烃副产混合碳五馏分利用的关键是其单烯烃组分的综合利用。

Coal-to-olefins, as a potential method instead of conventional oil route, has received wide attention in the past years. Mixed C5 fractions produced in methanol-to-olefins（MTO） process were commented in this paper that provided utilization means for mixed C5 fractions, and comprehensive utilization for C5 fration will bring the best economics for MTO plant by increasing the value of C5 byproducts.
