丁二烯是生产顺丁橡胶的主要原料,目前,我国主要采用P-Mo-Bi系催化剂于流化床中使丁烯氧化脱氢制取丁二烯为进一步提高催化剂的收率、转化率及选择性,我们研究了采用Sn-p-Li系催化剂制取丁二烯,根据本实验与φ51mm固定床的条件试验[5],收率、转化率、选择性均提高,分别达到70％、80％、90％左右。有机含氧化合物可降至3～5％。与p-Mo-Bi系催化剂比较,其反应设备简单,生产能力提高并减少对大气与地下水的污
Butadiene is the main raw material for the production of butadiene rubber. At present, P-Mo-Bi catalyst is mainly used to oxidize butadiene to butadiene in the fluidized bed. In order to further improve the yield and conversion rate of the catalyst, And selectivity, we studied the preparation of butadiene using Sn-p-Li catalyst, according to the experimental conditions and φ51mm fixed bed conditions [5], the yield, conversion, selectivity increased to 70% , 80%, 90% or so. Organic oxygen compounds can be reduced to 3 ~ 5%. Compared with the p-Mo-Bi catalyst, its reaction equipment is simple, its productivity is improved, and its pollution to the atmosphere and groundwater is reduced
