Abstract
This invention relates to acid catalysis of organic compound feedstock, e.g. isomerization of xylenes, over catalyst material treated in a special way for increasing the acid catalytic activity thereof. In particular, a novel catalyst activation process is followed to enhance the alpha value of high-silica zeolite catalyst by contact with an ammoniacal solution of an alkali metal aluminate under appropriate conditions of time, temperature and pH.
