| Abstract: | The DC-type catalyst, which is an iron-based catalyst for the dehydrogenation of ethylbenzene to styrene,has been developed and successfully utilized in several commercial units in China. It has been shown by these industrial applications that the performance of DC-type catalysts is comparable with the imported catalysts under similar reaction conditions. Operations in various commercial scales also showed that DC-type catalysts possessed high activity and selectivity,excellent mechanical strength as well as novel moisture-proof properties. A bi-layer configuration of catalyst loading combining the special features of the adiabatic reactor with that of the DC-type catalyst has been adopted, which can increase the catalyst selectivity by 4 percent,as compared with the single layer configuration. |
