正丁烯气相氧化制甲乙酮催化剂的研究

Study on catalyst for gas phase oxidation of nbutene to methyl ethyl ketone

用多步浸渍法制备的以钯为主的复合催化剂,对正丁烯一步氧化制甲乙酮有较高的催化活性。在140℃和大量水蒸汽存在下,正丁烯转化率约为90%,甲乙酮收率约为60%,选择率约为68%。

The complex catalyst prepared mainly on palladium by the multi-step impregnation process possesses a higher catalytic activity for one-step oxidation of n-butene to methyl ethyl ketone. At 140℃ and in the pressence of a great amount of steam,the conversion of n- butene is about 90%, the yield of methyl ethyl ketone is about 60% and the selectivity is about 68%.
