一种生产1,4-丁炔二醇催化剂及其制法和应用
摘要：
本发明公开一种生产1,4-丁炔二醇催化剂及其制法和应用。所述催化剂以氧化硅为载体，以铜铋化合物为活性组分，其组成按质量百分比计，氧化铜为30%~60%，氧化铋为2%~5%，氧化硅为余量；所述催化剂10~40μm颗粒直径至少在80%以上，比表面积为20~50m2/g，孔容为0.1~0.5cm3·g-1，孔径分布在10nm~50nm之间的占85%以上，堆积密度为1.0~1.8g·mL-1。该催化剂采用沉淀法制备。该催化剂具有耐磨性好、催化剂颗粒均匀、使用过程中不易流失等优点。
摘要（英）：

The invention discloses preparation of a 1,4-butynediols catalyst and a preparation method and an application thereof. The catalyst takes silicon oxide as a carrier and takes a copper-bismuth compound as an active component, by mass percentage, copper oxide accounts for 30-60%, bismuth oxide accounts for 2-5%, and the balance of silicon oxide. the particle diameter with 10-40 [mu]m of the catalyst accounts for at least more than 80%, specific surface area is 20-50 m<2>/g, and pore volume is 0.1-0.5 cm<3>.g<-1>, aperture distributed between 10-50 nm accounts for more than 85%, and the bulk density is 1.0-1.8 g.mL<-1>. The catalysts is prepared by using a precipitation method. The catalyst has the advantages of good wear resistance, uniform catalyst particle, and difficult loss during a usage process.
