In a process for producing dialkylbiphenyl compounds, a feed comprising substituted cyclohexylbenzene isomers having the formula (I): [ Formula (I) should be inserted here] wherein each of R1 and R2 is an alkyl group and wherein the feed comprises m % by weight of isomers in which R1 is in the 2-position, based on the total weight of substituted cyclohexylbenzene isomers in the feed; is transalkylated with a compound of formula (II): [ Formula (II) should be inserted here] to produce a transalkylation product comprising substituted cyclohexylbenzene isomers having the formula (I) and including n % by weight of isomers in which R1 is in the 2-position, based on the total weight of substituted cyclohexylbenzene isomers in the transalkylation product, wherein n
摘要:
The invention relates to a process for the production of linear alkanes, containing less than 6'carbon atoms, from a mix comprising one or more hydrocarbons containing at least 6 carbon. atoms. The process uses a catalytic composition comprising particular combinations of a Y-type zeolite, at least one element selected from Zn, Mo, Cu, Ga, In, W, Ta, Zr, Ti, metals of Group VIII and optionally one or more lanthanides.
