Abstract

The present invention relates to a kind of C obtained by carbon-carbon coupling of lignocellulose-based platform compound 8 -C 16 A new method for preparing aviation kerosene range hydrocarbons through hydrodeoxygenation reaction of furyl oxygen-containing organic compounds as raw materials. The low-temperature direct hydrodeoxygenation of furanyl oxygen-containing organic compounds under solvent-free conditions was realized by using a metal-solid acid bifunctional catalyst, and a series of branched alkanes with low freezing points in the range of aviation kerosene chain lengths were obtained in high yield. This type of catalyst is composed of active metal A and acid carrier X. The catalyst involved in the present invention has the characteristics of no solvent, simple operation process, mild reaction conditions, good selectivity of aviation kerosene (or diesel oil), etc., and is an ideal method for preparing liquid fuel by hydrodeoxygenation of furan-based oxygen-containing organic compounds. Hydrodeoxygenation catalyst.

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...
