Abstract

The invention discloses a method for preparing 2,5-dimethylfuran by catalytic hydrogenation of 5-hydroxymethylfurfural, which comprises the following steps: reacting 5-hydroxymethylfurfural used as araw material in a reaction solvent under the action of a supported bifunctional catalyst in a hydrogen atmosphere to obtain the 2,5-dimethylfuran. The supported bifunctional catalyst herein comprisesa carbon carrier and an effective active component supported on the carbon carrier, wherein the carbon carrier is one of activated carbon, mesoporous carbon or nitrogen-doped mesoporous carbon, and the effective active component comprises oxides of nickel and manganese. The yield of the 2,5-dimethylfuran synthesized by the method is more than 90%; wherein the method is simple in process, high in selectivity, clean, environmentally friendly, small in catalyst dosage, capable of reducing cost and suitable for industrial production.

Description

technical field

[0001] The invention relates to the technical field of bioenergy, in particular to a method for preparing 2,5-dimethylfuran through catalytic hydrogenation of 5-hydroxymethylfurfural. Background technique

[0002] With the depletion of non-renewable fossil resources such as coal, oil and natural gas, the research on the production of fuels and chemicals by using typical renewable resource biomass, especially lignocellulosic biomass, as a substitute has attracted more and more attention. Lignocellulose can be converted into bulk platform compounds and biofuels. Among them, biomass-based 2,5-dimethylfuran (2,5-DMF) has an energy density of 30MJ / L, a boiling point of 92-94°C, and an octane number of 119. It is an important platform compound and very Promising renewable liquid biofuels. Especially as a biofuel, it has higher energy density, boiling point and octane number than traditional fuel ethanol, and has better explosion-proof performance. It is a new typ...
