碳四馏份选择加氢工艺及催化剂的研究

The Process of C_4 Fraction Selective Hydrogenation and the Catalyst

碳四馏份选择加氢催化剂及工艺条件进行了研究 ,经工业侧线评价试验表明 ,含有质量分数 0 9%～ 1 3 %炔烃的碳四馏份经该催化剂加氢处理后 ,其炔烃质量分数可脱除至 <1.5× 10 - 5,丁二烯损失 <1 5 % (质量分数 )。经6 40h考核 。

The process of selective hydrogenation of C 4 fraction and the catalyst employed was studied. Industrial side-line evaluation test shows that alkyne contents in C 4 fractions can be reduced from the original 0.9%～1.3% to less than 1.5×10 -5 by catalytic selective hydrogenation with multi-metal catalysts.The loss in butadiene is less than 1.5%.The catalyst still maintains high activity and selectivity after reaction for 640 h.
