| titleOfInvention | A method for flexible production of tetrahydrofuran and gamma-butyrolactone |
| abstract | The invention relates to a method for flexibly producing tetrahydrofuran and γ-butyrolactone. Under the condition of facing hydrogen, the 1,4-butanediol raw material is sequentially passed through the first catalyst bed and the second catalyst bed, and after the reaction, the γ-butyrolactone containing The product of tetrahydrofuran and γ-butyrolactone; the first catalyst bed is loaded with a dehydrogenation catalyst, and the second catalyst bed is loaded with a catalyst with dehydration and specific hydrogenation performance, by adjusting the first catalyst bed and the second catalyst bed. The catalyst loading ratio is used to adjust the ratio of THF and γ-butyrolactone in the reaction product. The method of the present invention can be flexibly adjusted according to market demand for tetrahydrofuran and γ-butyrolactone. |
