摘要
Abstract
In order to adjust the ratios of BTX aromatics,the conversions of benzene and toluene and the selectivities of various products were studied. The reactions of benzene with methanol or syngas and toluene with methanol were compared. When the syngas and methanol were used as methylation reagent, respectively, the conversions of benzene were 36.81% and 39.98%, rerspectively, and the selectivities of various aromatics were similar, but the water selectivity of syngas was much higher than that of methanol. In addition, the conversion of methanol is higher than that of syngas. When methanol was used as methylation reagent to react with benzene and toluene, respectively, the performance indicators related to aromatics, methanol and hydrogen were similar, indicating that the the reactions of methanol with benzene or toluene have roughly the same performance.This paper provides a basis for the future selection of methylation reagents.关键词
