In said process, ethylbenzene is produced by alkylation of benzene in vapour phase in the presence of a catalyst containing ZSM-5. The by-product of diethylbenzene produced by vapour phase alkylation is separated from ethyl-benzene, and subjected to alkyl transfer reaction with benzene in liquid ...
PURPOSE:To produce the subject compound in a high selectivity and in a high yield by reacting toluene with methane in the presence of O2 and a catalyst prepared by making carry an alkali metal oxide on a carrier selected from alkaline earth metal oxides, alkaline earth metal carbonates and rar...
The production of ethylbenzene from dilute ethylene and dilute benzene is accomplished in three steps. First, the benzene feedstock stream, containing benzene, is alkylated with the dilute ethylene feedstock stream, containing ethylene, to form ethylbenzene along with polyethylbenzenes (PEB) which includ...
Consequently, using a palladium-based membrane reactor (MR) enhances the primary reaction of dehydrogenating ethylbenzene (EB). The EB conversion performance in the MR was 7.5 % higher than those obtained in the TR at 600 °C. However, elevated temperatures also promote side reactions, such as...

The main compounds produced from sawdust consisted of hepta-3,5-dien-2-one, ethylbenzene, p-xylene, and 1,4-dimethylbenzene, which are characteristic of bio-jet, demonstrating its effectiveness with a 29% yield. In contrast, the use of biochar, activated carbon, and other intermediate ...
The reaction properties of Pt/Al_2O_3 in the dehydrogenation of ethylbenzene was studied andthe technological conditions such as reaction temperature,pressure,LHSV and diluent amountwere examined. The results show that the improved Pt/Al_2O_3 catalyst possesses stable and effective properties.The co...
aThis unit is the production of ethylene and benzene as raw materials, in molecular sieve catalysts for alkylation reaction of Ethylbenzene under the action, producing by-products of Ethylbenzene and its recombinant. 这个单位是乙烯和苯的生产作为原材料,在分子筛催化剂为乙苯的烷化反应在行动之下,导致副...
the alkylation reaction,the changes of the product composition in alkylation reaction could be judged correctly,which could provide useful reference to ensure the long term stable running of the plant. Key words:organic chemical engineering;dilute ethylene method;ethylbenzene;impurities in raw ma teri...
In this review, only the C6-C8+ (including ethylbenzene) were considered in the comparison. Partial conclusions Figure 8 shows some of the more important results. Depart- ing from real feeds a total BTX yield higher than 35% was never attained using a hydrocracking catalyst of any type...
