Poster: Možnosti potlačení dezaktivace katalyzátorů pro aromatizaci metanu

Popis výsledku v původním jazyce

During the past 20 years the valorization of natural gas has become a highly developed and mature research field and various processes have been developed to convert the most abundant hydrocarbon into useful chemical products, those are, higher aliphaticand aromatic hydrocarbons. One of them is the direct non oxidative methane aromatization carried out on the shape selective microporous materials. During catalytic reaction, on the surface of the zeolite crystals and in their porous structure the carbondeposits are formed and the catalysts are quickly deactivated. Partial suppression of catalyst deactivation and catalyst regeneration are studied in presented work. Two ways leading to the more stable catalyst performance were proposed and experimentally tested: (i) CO2 addition to feed, (ii) Mo-ZSM5 catalyst modification by Co. The regeneration of deactivated catalyst by the direct oxidation were tested also. Catalytic activity of Mo-catalysts prepared by wet impregnation of ZSM-5 from
