采用恩氏蒸馏、辛烷值测定机及气相色谱等手段,对神华宁煤MTP装置副产的汽油组分进行了详细的定性和定量分析,探讨了其增值利用方案。结果表明,神华宁煤MTP装置副产的汽油为高辛烷值油品,具有馏程变化范围窄,芳烃、烯烃含量高等特点,芳烃和烯烃质量分数分别为48%和25%。根据结果,提出了几种副产物增值利用的方案,其中增产丙烯和乙烯方案可作为首选方案。 By means of Enzine distillation, octane number measuring machine and gas chromatography, the gas components by-product of Shenhua Coal MTP plant were analyzed qualitatively and quantitatively, and the value-added utilization scheme was discussed. The results show that the by-product gasoline from Shenhua Coal MTP unit is a high-octane oil with a narrow range of distillation range, high aromatics and olefin content, and the mass fraction of aromatics and olefins is 48% and 25% respectively. According to the results, several plans for value-added utilization of by-products are proposed, of which propylene and ethylene production can be increased as the first choice.
