Process for producing a dealuminated zeolite ZSM-5 shaped catalyst

摘要

A method for producing a dealuminated zeolite ZSM-5 shaped catalyst comprising adding from 30 to 40 parts by weight of powdered dealuminated zeolite ZSM-5 containing tetrapropylammonium cations with 15 to 25 parts by weight of tetraethyl orthosilicate, 6 to 9 parts by weight of at least one oleyl group containing component. and 2 to 8 parts by weight of polyethylene glycol having a molecular weight of 400 g / mol. The resulting mixture is extruded through a die having 2 to 3 mm holes. The resulting extrudates are dried at 90 to 110 ° C and then calcined in an air stream at 520 to 540 ° C for 8 to 10 hours. The oleyl group-containing component may be oleic acid or vegetable oil.
