Abstract
This invention discloses a catalyst for preparing 2,5-dimethylfuran, its preparation method, and its application. The catalyst comprises a Ni-SCM-X molecular sieve, where X is 14 or 15; Ni includes metallic Ni and Ni14. 2+ , where Ni / Ni 2+ The molar ratio is 0.02–0.15. This catalyst, when used in the preparation of 2,5-dimethylfuran, exhibits high efficiency in the conversion of 5-hydroxymethylfurfural under mild reaction conditions, high selectivity for the product 2,5-dimethylfuran, and outstanding stability during catalyst recycling.
