In this work, the selective conversion of hexanoic acid to hydrocarbons using Cu/β-zeolite-EG prepared by the ethylene glycol (EG) assisted impregnation method was investigated. It was found that Cu/β-zeolite-EG shows higher selectivity towards benzene, toluene and xylenes (BTXs) as well as higher resistance to coke deposition when compared to Cu/β-zeolite prepared by a conventional impregnation method. This should be attributed to the better dispersion and stronger interaction between the active Cu species and the β-zeolite surface in the Cu/β-zeolite-EG solid. This catalytic system shows potential practical application in the upgrading of bio-oil.

在这项工作中，研究了使用乙二醇（EG）辅助浸渍法制备的Cu /β-沸石-EG将己酸选择性转化为烃类。已经发现，与通过常规浸渍方法制备的Cu /β-沸石相比，Cu /β-沸石-EG对苯，甲苯和二甲苯（BTX）表现出更高的选择性以及更高的抗焦炭沉积性。这应该归因于活性Cu物质与Cu /β-沸石-EG固体中的β-沸石表面之间的更好的分散和更强的相互作用。该催化系统在生物油的提纯中显示出潜在的实际应用。
