一种选择加氢除炔多金属催化剂
摘要：
本发明提供了一种选择加氢除炔多金属催化剂。包括以下组份：含量为1-30%wt的Cu，含量为0.001-5%wt的Pd，选自氧化铝、氧化硅或氧化钛中的至少一种载体。此外，还可包括含量为0.001-6%wt且选自铋、锆、铅、银、铂中的一种或多种助剂金属。采用本发明催化剂，碳四馏份的炔含量可降至15ppm以下，1，3-丁二烯损失可小于1.5%wt。
摘要（英）：

A catalyst for selective hydrogenation, which comprises, on the basis of the total weight of catalyst, 1-30wt% of copper as the first active component, 0.001-5wt% of palladium as the second active component, 0.001-6wt% of at least one metal selected from Ag, Pt, Pb, Mn, Co, Ni, Cr, Bi, Zr and Mo as cocatalyst, and the balance of at least one support selected from alumina, silica or titania. The present invention further relates to its preparation, its use in removal of alkynes from alkyne-enriched C4 cuts through selective hydrogenation and its regeneration.
