About Paper:

Non-oxidative methane to ethylene conversion occurs at high temperatures, using catalysts such as zeolite templated carbons (ZTC). Though ZTC is a good catalyst for non-oxidative methane to ethylene conversion, this reaction must occur at high temperatures, and ZTC is notable for decomposition at high temperatures. Our research aims to conduct a methane dehydroaromatization (MDA) experiment using synthesized ZTC and commercial zeolites faujasite (FAU), chabazite (CHA), and Beta (BEA) with molybdenum (Mo) under differing gas environments and temperature conditions. The initial step of this process is Molybdenum zeolite synthesis for each zeolite framework tested. Synthesis includes use of a mortar and pestle, pellet press, and heating the mixture overnight in a furnace to create a Mo-zeolite template for each commercial zeolite. After synthesis, each synthesized zeolite template will undergo a methane dehydroaromatization reaction. As a result, ZTC materials will be extracted from the synthesized materials and characterized. Each ZTC material will undergo characterization using gas physisorption and x-ray diffraction. Based on our results we can conclude which ZTC material is the most stable and what conditions are deemed most favorable for thermal stabilization of the ZTC materials. Future research will focus on testing zeolites with differing frameworks and recycling coke materials into useful materials. Keywords: ZTC; Molybdenum; Zeolites; MDA
