| Abstract: | A norel 345 catalyst for preparing styrene by ethylbenzene dehydrogenation was developed. The catalyst had high activity, high selectivity,good resistance to moisture and improved mechanical strength. The activity evaluation of catalyst showed that the catalyst had stable properties,the ethylbenzene conversion was more than 75%, styrene selectivity was more than 95%, styrene yield was more than 72%, which was similar to those of G-84C or its improved grades. The catalyst had notable economic benefit in commercial application. |
