Oxygen-Free Oxidative Dehydrogenation of Ethane over VO_x/γ - Al_20_3 Catalyst in Riser Reactor Simulator

摘要

Light Olefins, specifically ethylene and propylene, represent the most important building blocks for the petrochemical industry. Steam cracking of hydrocarbon feedstock (ethane, LPG, or naphtha) has been the major source of light olefin accounting for 70% of total olefin production (1). Other methods for olefin production such as fluidized catalytic cracking (FCC) and direct dehydrogenation are also in use. Fluidized catalytic cracking (FCC) is the second most frequently used processes for olefin production accounting for 28% of total olefin production (2). In FCC, ethylene and propylene are produced as co-products during gasoline production with ethylene and propylene in yields of 1-2% and 5%, respectively
