Experimental and modeling studies using packed bed reactors: Liquid phase ethylene production by hydrogenation of acetylene
… catalytic hydrogenation of acetylene to produce ethylene, commonly practiced in industries, has green oil formation, which leads to catalyst deactivation and sometimes reactor runaway risks due to high exothermicity. To overcome these issues as well as to increase the selectivity and conversion, …
