Problems solved by technology

[0004] At present, aviation kerosene and diesel are mainly produced from coal and petroleum. Coal and petroleum are non-renewable energy sources. In the process of manufacturing and using aviation kerosene and diesel, a large amount of carbon dioxide and sulfur dioxide will be produced, causing greenhouse effect and environmental pollution.

Abstract

The invention discloses biomass liquid fuel, a preparation method and application thereof. The method comprises the following steps: performing one-pot condensation and selective hydrogenation on cyclopentanone and furfural, so as to obtain 2, 5-bis (furan-2-methylene) cyclopentanone; performing hydrodeoxygenation reaction on the 2, 5-bis (furan-2-methylene) cyclopentanone through a supported metal catalyst, so as to obtain the biomass liquid fuel with the carbon chain length being C10 to C15. The biomass liquid fuel has the advantages that the alkane yield of the biomass liquid fuel reaches greater than 86 percent, the biomass liquid fuel can serve as high-quality aviation kerosene or high-quality diesel, or can serve as an additive of aviation kerosene or diesel.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a biomass liquid fuel and its preparation method and application. Background technique [0002] The rapid consumption of fossil energy will lead to its depletion and environmental pollution. Catalytic conversion of renewable biomass lignocellulosic (cellulose, hemicellulose and lignin) resources to synthetic fuels and fine chemicals has attracted great attention of researchers. [0003] Aviation kerosene and diesel oil are two commonly used transportation fuels. Aviation kerosene is a kind of fuel specially prepared for aircraft. In order to ensure the normal flight of aircraft at an altitude of 10,000 meters, very strict standards have been set for aviation fuel, which requires high calorific value ( >43MJ / kg), moderate density (0.775~0.840g / cm 3 ), low freezing point (Jet A1≤-47℃, Jet A1≤-40℃) and good kinematic viscosity (≤8.0mm at -20℃ 2 / s) and other tec...
