摘要 对自研加氢催化剂粉体进行了模压成型研究,并与外购催化剂进行了工业侧线的试验比较。相同工艺条件下,自研催化剂的草酸酯转化率为100%,乙二醇选择性达到97%,而且强度明显超过外购催化剂。在百吨级工业侧线上,自研催化剂的草酸酯转化率达到100%,而乙二醇选择性超过外购催化剂1%~2%。反应废液浸泡8个月后,自研催化剂仍保持较好的催化活性和较低的气阻,无粉化现象。新鲜催化剂在稳定的工艺条件和足够的氢酯比下表现出了优异的稳定性和催化性能。

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.
