Abstract

The invention relates to a new method for preparing hydrocarbons in the scope of aviation kerosene from C8-C16 furyl oxygen-containing organic compounds as raw materials by hydrogenation deoxidation reaction, wherein the C8-C16 furyl oxygen-containing organic compounds are obtained by C-C coupling of lignocellulose based platform chemical compounds; low temperature direct hydrogenation deoxidation under the condition of no solvent of the furyl oxygen-containing organic compounds can be realized by use of a metal-solid acid dual-functional catalyst to obtain a series of low freezing point branched alkanes having the chain in the length range of the aviation kerosene in high yield. The catalyst is composed of two parts of an active metal A and an acid vector X. The catalyst related in the method ahs the characteristics of being in no need of a solvent, simple in operation process, mild in reaction conditions, good in aviation kerosene (or diesel) selectivity, and the like, and is an ideal hydrogenation deoxidation catalyst for preparing liquid fuels from the furyl oxygen-containing organic compounds by the hydrogenation deoxidation.

Description

technical field [0001] The invention relates to a new method for preparing aviation kerosene range hydrocarbons by hydrodeoxygenating aviation kerosene precursors obtained by carbon-carbon coupling of lignocellulose-based platform compounds as raw materials. The direct hydrodeoxygenation of furan-based oxygenated organic compounds under mild solvent-free conditions was achieved by using supported metal-solid acid bifunctional catalysts, and a series of aviation kerosene (or diesel) chain length hydrocarbon compounds were obtained in high yield. Compared with the existing hydrodeoxygenation method of furanyl oxygen-containing organic compound, the method has the advantages of no solvent, simple operation process, low energy consumption, low cost and the like. Background technique [0002] Aviation kerosene is a liquid fuel in great demand in the world at present, and it is a strategic material of a country. There are many types of it, and it is generally composed of chain al...
