| abstract |
The invention relates to the field of styrene production, and discloses a method for producing styrene. The method comprises: under anhydrous conditions, (1) first contacting a raw material containing ethylbenzene with an iron-potassium-cerium-based catalyst to generate a stream W; (2) secondly contacting the stream W with the nanodiamond catalyst to obtain styrene. The method provided by the invention has the characteristics of low cost, suitable for long-term operation, and high ethylbenzene conversion rate and styrene selectivity. |
