Abstract: The research about molding of self-developed hydrogenation catalyst is performed,and industrial side-stream experiments are conducted for comparing the self-developed catalyst with outsourcing catalyst.Under the same process conditions,the conversion of oxalate and the selectivity of ethylene glycol over the self-developed catalyst can reach 100% and 97%,respectively,and the strength of the self-developed catalyst is obviously higher than that of outsourcing catalyst.Under a 100 t/a industrial side stream test,the conversion of oxalate over the self-developed catalyst can reach 100% and the selectivity of ethylene glycol can surpass that of outsourcing catalyst by 1%-2%.After 8 months immersion in waste liquid,the self-developed catalyst can still maintain a good catalytic activity,a low gas resistance and no pulverization phenomenon.After long soak in reaction liquid waste for 8 months,the self-developed catalyst can keep good catalytic activity and lower vapor lock which signifies no pulverization.The novel catalyst puts up nice stability and activity under stable process conditions and sufficient ratio of hydrogen to oxalate.
