Abstract

The invention relates to the technical field of biomass energy and chemical industry, particularly to a preparation method of novel bio-gasoline. The method adopts citric acid industrial waste thallus Aspergillus niger as a raw material, and by means of the intermediate products chitin, 5-hydroxymethylfurfural, and 5-ethoxy methyl furfural, the bio-gasoline can be prepared. The preparation method of novel bio-gasoline provided by the invention uses citric acid industrial waste thallus Aspergillus niger as the raw material, so that the pressure of environmental pollution can be substantially relieved, and the prepared bio-gasoline product has high energy density. Also, combustion in the engine is smooth and thorough, and the carbon deposits are fewer.

Description

technical field [0001] The invention relates to the technical field of biomass energy chemical industry, in particular to a preparation method of novel biogasoline. Background technique [0002] With the depletion of fossil energy and the urgent need to develop a low-carbon economy, the development and research of new renewable energy has become a major issue facing the world today. Biomass energy comes from biomass, and because of its extensive sources and renewable characteristics, it has attracted more and more attention from researchers at home and abroad. [0003] At present, the main raw materials for biogasoline production are agricultural wastes rich in lignocellulose, and the production methods are mainly through hydrolytic reforming or high-temperature pyrolysis. CN 101671571A discloses a method for preparing biogasoline by hydrolyzing and reforming lignocellulosic biomass as raw material. 2 -Al 2 o 3 The low-temperature reforming reactor and the high-temperatu...
