Abstract

The invention provides a method for preparing γ-valerolactone, valeric acid and valeric acid ester from biomass platform molecules. The method prepares γ-valerolactone with levulinic acid ester as a reaction raw material, prepares valeric acid and valeric acid ester with γ-valerolactone or levulinic acid ester as a raw material, and realizes the preparation of γ-valerolactone, The hydrogenation of γ-valerolactone to prepare valeric acid and valeric acid esters, or levulinic acid esters is a process for preparing valeric acid and valeric acid esters in one step with high efficiency, high selectivity and high yield. Valeric acid ester compounds can be used as biofuels, and are well compatible with existing fuel oil systems. Using the reaction provided by the invention to prepare valeric acid and valeric acid esters has significant advantages such as biomass resources as raw materials and atom economy. At the same time, compared with other technologies that use levulinic acid as raw material to prepare valeric acid and valeric acid ester, this method has the characteristics of simple reaction process, high yield of target product, mild reaction conditions and medium, simple and stable catalyst preparation process .

Description

A method for preparing biomass fuel molecules by hydrogenation of biomass platform compounds technical field The present invention relates to a kind of preparation method of biomass fuel oil molecule, specifically by biomass platform compound B The preparation of γ-valerolactone from levulinic acid ester, the preparation of valeric acid and valeric acid ester by hydrogenation of γ-valerolactone, or the one-step hydrogenation of levulinic acid ester to produce The method for preparing valeric acid and valeric acid ester. Background technique [0002] Valerate is a novel green energy liquid fuel molecule that can be prepared from renewable biomass resources. Lange et al. of the Royal Dutch Shell laboratory reported for the first time the preparation of a new type of "pentane" based on the hydroconversion of levulinic acid. ester biofuels”, and a comprehensive study of the properties of this type of fuel has been carried out. Compared with alcohol, butanol, ethyl levuli...
