DEHYDROGENATION CATALYST HAVING A BIMODAL PORE SIZE DISTRIBUTION |
摘要 |
A method for improving the selectivity of iron oxide based dehydrogenation catalysts is presented. In one aspect of this invention the catalyst is made from an iron-containing compound having iron oxide particles which display a bimodal pore-size distribution. A process for preparing iron oxide dehydrogentation catalyst is also presented in which an iron-containing compound having iron oxide particles which display a bimodal pore-size distribution is combined with a potassium containing compound and water, this mixture is then formed into a pellet, and the pellet is calcined. The catalysts are particularly useful in the preparation of styrene from ethyl benzene. |
