| titleOfInvention | Low-water-ratio ethylbenzene dehydrogenation catalyst and preparation method thereof |
| abstract | The invention relates to an ethylbenzene dehydrogenation catalyst with a low water ratio and a preparation method thereof, and mainly solves the problems of poor stability and low activity of a low-potassium catalyst under the condition of the low water ratio in the prior art. The invention adopts a low water ratio ethylbenzene dehydrogenation catalyst, which comprises the following components in percentage by weight: 66-79% Fe 2 O 3 (ii) a 4 to 8% of K 2 O; 6-11% of CeO 2 (ii) a 1-5% of WO 3 (ii) a 0.5-5% SrO; 0.5 to 8% of Li 2 O; 0.5-5% of medium rare earth oxide; the rare earth oxide is selected from Pm 2 O 3 、Tb 2 O 3 Or Ho 2 O 3 The method can be used for industrial production of styrene by ethylbenzene dehydrogenation under the condition of low water ratio. |
