Abstract
The alkylation or transalkylation of aromatic hydrocarbon feeds (opt. contg. monpolar substits.) is carried out by contacting the feed with a (trans)alkylating agent at an inlet temp. of 38-650 degrees C, an absolute presS. of 1.03-210 (pref. 1.75-56) kg/cm2, a molar ratio of aromatic hydrocarbon to (trans)alkylating agent of 1:3 to 20:1 and a WHSV of 0.5-1000 (pref. 1-20) in the presence of a zeolite of the ZSM-21 type (x-ray diffraction data given). Catalysts bssed on zeolites of the ZSM-21 type have high stability and high selectivity.
