The interactions between gallium and H-ZSM-5 on gallium-supported H-ZSM-5 catalysts were investigated. Gallium was introduced into H-ZSM-5 by impregnation [Ga/Z5(im)] and physical mixing [Ga/Z5(mix)]. Temperature-programmed desorption studies of ammonia show that the number of strong acid sites (HTP
