用于丁烯氧化脱氢制丁二烯的负载型催化剂及其制备方法
摘要：
本发明涉及一种用于丁烯氧化脱氢制丁二烯的负载型催化剂及其制备方法，该方法采用共沉淀、浸渍、焙烧改性和研磨成型等步骤制备丁烯氧化脱氢催化剂，制得的催化剂通式为AaBbCcDd·FexOe；其中A为Cu、Zn、Cr、Ni中的一种；B为Co、Mn、Mo、Sn中的一种；C为Ca、Sr、Ba、Mg中的一种；D为W。该催化剂用于固定床的丁烯氧化脱氢制丁二烯，丁二烯的产率为77～82％，丁二烯的选择性为92～95％。
摘要（英）：

The invention relates to a supported catalyst used for butylene oxidative dehydrogenation to prepare butadiene, and a preparation method thereof. The method is characterized in that the butylene oxidative dehydrogenation catalyst is prepared through co-precipitation, dipping, roasting modification and grinding molding steps, and the general formula of the prepared catalyst is AaBbCcDd.FexOe, wherein A is one of Cu, Zn, Cr and Ni, B is one of Co, Mn, Mo and Sn, C is one of Ca, Sr, Ba and Mg, and D is W. The catalyst is used in fixed bed butylene oxidative dehydrogenation for preparing butadiene, the butadiene yield is 77-82%, and the butadiene selectivity is 92-95%.
