Process for producing a dealuminated zeolite ZSM-5 shaped catalyst

摘要

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