Chemical looping hydrogen
WebNov 1, 2024 · The coke-oven gas direct chemical looping hydrogen generation is a promising process for chemical industry; however, it still suffers from high energy consumption and low hydrogen production. The chemical looping-derived H 2 and N 2 can be used to produce ammonia. Therefore, a new process for coke-oven gas … Web2 days ago · The chemical-looping processes could combine the advantages of non-oxidative and oxidative EDH reactions by removing hydrogen—high reaction temperatures are required in most cases —and showed experimental ethane conversion lower than that at equilibrium (equilibrium at the used temperature for non-oxidative EDH).
