Abstract
Effects of alkali metal halides promoter on the oxidative methylation of to luene with methane over KY zeolite catalysts were systematically studied. I n terms of the catalytic activity for the oxidative methylation of toluene with methane over those catalysts, the following order was observed: NaBr/K Y>KBr/KY>NaCl/KY. The C-8 products containing much styrene were gained over alkali metal bromide promoted KY zeolite catalysts. The acidity and basici ty of these catalysts were studied by using NH3-TPD and formic acid-TPD. (C ) 1999 Elsevier Science B.V. All rights reserved.
