Both succinic anhydride and 1, 4-butanediol can be prepared from maleic anhydride. Usually succinic anhydride is prepared by direct hydrogenation of maleic anhydride by using a noble metal Pd catalyst or a non-noble metal Ni catalyst, Chinese patent with publication number CN105833863A discloses a supported palladium catalyst for preparing succinic anhydride by low-temperature hydrogenation of maleic anhydride and a preparation method and application thereof, and Chinese patent with publication number CN101502802B discloses a Ni-based supported catalyst for continuously producing succinic anhydride by hydrogenation of maleic anhydride and a preparation method and application thereof. Usually, the 1, 4-butanediol is indirectly prepared by esterification and hydrogenation of maleic anhydride, reports on the preparation of the 1, 4-butanediol by direct hydrogenation of the maleic anhydride are few, and Chinese patent with the authorization number of CN1049207C discloses a method for preparing the 1, 4-butanediol by direct hydrogenation of the maleic anhydride and/or the succinic anhydride as raw materials under the action of a catalyst, the active components of the method are Cu, Zn, Cr and the like, and the results of 100 percent of maleic anhydride conversion rate, 66 percent of 1, 4-butanediol selectivity, 26 percent of gamma-butyrolactone selectivity and 4 percent of tetrahydrofuran selectivity are obtained under the conditions of 228 ℃ of reaction temperature, 7MPa of reaction pressure, 0.1h < -1 > of LHSV and 300 of hydrogen-anhydride ratio.
