摘要: This invention relates to a process for the selective alkylation of toluene and/or benzene with an oxygen-containing alkylation agent. In particular, the process uses a selectivated molecular sieve which has been modified by the addition of a hydrogenation component, wherein at least one of the following conditions is met: (a) the selectivated molecular sieve has an alpha value of less than 100 prior to the addition of the hydrogenation component, or (b) the selectivated and hydrogenated catalyst has an alpha value of less than 100. The process of this invention provides high selectivity for the alkylated product while reducing catalyst degradation.

摘要: A process is described for isomerizing a feed which contains ethylbenzene and xylene, which process comprises the steps of:(a) contacting the feed under ethylbenzene conversion conditions with a particulate first catalyst component which comprises a molecular sieve having a constraint index of 1-12, the particles of said first catalyst component having a surface to volume ratio of about 80 to less than 200 inch.sup.-1 and the contacting step converting ethylbenzene in the feed to form an ethylbenzene-depleted product; and then(b) contacting the ethylbenzene-depleted product under xylene isomerization conditions with a second catalyst component.
