Název v původním jazyce

Effect of addition of a second metal in Mo/ZSM-5 catalyst for methane aromatization reaction under elevated pressures

Popis výsledku v původním jazyce

Non-oxidative methane dehydro-aromatization (MDA) over transitional metal-doped zeolites (i.e. ZSM-5) has a potential to be an alternative for methane transformation processes to higher hydrocarbons. Despite of systematic studies of the effects of the catalyst composition, preparation procedure, pretreatment, and the reaction conditions systematically followed since the pioneering works of the Chinese group in 1993, the suppression of fast deactivation of catalyst by coke deposition was still not solvedsuccessfully. In the present work the long-term MDA experiments at 973 K and elevated pressures up to 600 kPa were carried out with metal-doped Mo/ZSM-5 catalysts. Several Mo-based catalysts doped with various amount of Co, Mn, and Ce were prepared andtested in the MDA reaction. Experimental results are presented in terms of profiles of methane conversion as well as ethylene, benzene, and toluene concentrations as a function of time on stream, accompanied by the TGA analysis of the cok
