Abstract

Hydrothermal treated catalyst was prepared by treating CBV8020 (HZSM-5) at 500°æ for 6 hr in 100% water vapor and followed by the treatment with HCl solution at room temperature. Methylation of 4-methylbiphenyl (4-MBP) with methanol under fixed-bed down-flow conditions was used to evaluate the catalytic properties of the prepared catalyst. Hydrothermal treatment removed aluminum from the framework, but the aluminum still remains in the zeolite solid. After hydrothermal treatment, the catalytic selectivity to 4,4′-DMBP was ≤ 70%, while the 4-MBP conversion was about 12%. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA 8/22-26/2004).
