- Abstract
Mo/ZSM-5 catalysts were tested in methane dehydroaromatization reaction. The catalyst samples were pretreated in different ways before the testing. One of the samples was deep bed treated without molybdenum loading, one was deep bed treated after molybdenum loading. In other samples the parent zeolite was desilicated, or the extraframework aluminum was extracted after deep bed treatment. These samples were compared with a catalyst sample, which was not pretreated before the reaction. On all parent zeolites the molybdenum was deposited from the solution of ammonium molybdate. The catalysts were characterized by XRD, TPDA, FT-IR, n-exane cracking, and the surface properties were measured by nitrogen adsorption.
