The background technology is as follows:
the synthesis of high value-added chemicals using biomass-based materials is a novel way and a viable solution for comprehensive utilization of biomass resources, wherein the preparation of pentanediol by hydroconversion of furfural is one of the most representative examples. At present, the biomass raw material can be used for preparing the furfural in large quantities on an industrial scale, which provides a premise for converting the furfural into other high-added-value chemicals. Through ring opening and hydrogenation reaction, furfural can be further converted into pentanediol through tetrahydrofurfuryl alcohol (THFA) intermediates, and the pentanediol can be widely applied to the fields of polyester materials, plasticizers, coatings and the like, and has extremely high market application prospects.
The high-efficiency stable hydrogenation catalyst is a main factor limiting the large-scale application of the scheme, and the catalytic activity can be effectively improved by good structural design of the catalyst and loading of active metal sites. CN114073967a discloses an application of a nickel-containing catalyst in preparing 1, 5-pentanediol from furfural, the catalyst uses tungsten oxide-alumina composite oxide as a carrier, the active components are Ni and Pt group metal elements, and one or more of the Ni and Pt group metal elements are combined to form an alloy, so as to prepare the supported nickel-containing alloy catalyst. CN 106732602B discloses a catalyst for preparing pentanediol by catalyzing direct hydrogenolysis of furfural, and the catalyst with Pt supported by a composite oxide carrier of magnesium, cobalt or aluminum can prepare pentanediol with high conversion rate and high selectivity. CN 113318735A also discloses the application of the composite oxide supported Pt catalyst in preparing pentanediol from furfural, which is characterized in that: the composition of the catalyst is Pt/MMgO x X is more than or equal to 2 and less than or equal to 3; wherein the carrier is MMgO x M is any one or more than two of Ti, fe and Ce metals. However, the above-described technique is still further improved.
