PROMOTERS FOR CONTROLLING ACIDITY AND PORE SIZE OF ZEOLITE CATALYSTS FOR USE IN ALKYLATION |
摘要 |
A metal-modified alkylation catalyst including a metal/zeolite is provided where the metal is one or two selected from the group consisting of yttrium and a rare earth of the lanthanide series other than cerium. Where two metals are used, one may be Ce or La. The metal-promoted zeolite is useful as a molecular sieve aromatic alkylation catalyst for the production of ethylbenzene by the ethylation of benzene in the liquid phase or critical phase. An alkylation product is produced containing ethylbenzene as a primary product with the attendant production of heavier alkylated by-products of no more than 10-60 wt % of the ethylbenzene. |
