Embodiment 1

[0049] The invention provides a device and a method for preparing bio-aviation fuel based on ketone platform compounds. This method converts biomass into ketones and other monofunctional compounds through directional catalytic conversion, in which ketones undergo aldol condensation and hydroisomerization to prepare alkanes (including paraffins and cycloalkanes), and monofunctional compounds are catalyzed by zeolites to obtain aromatic hydrocarbons. Mix paraffins, cycloalkanes and aromatics in a certain proportion to prepare aviation fuel.

[0050] The device includes a catalytic pyrolyzer 1, a cyclone separator A 2, a liquid product collector 3, a ketone separator 4, an aldol condensation reactor 5, an organic matter-water separator 6, a hydroisomerization reactor 7, a compressor Machine 8, hydrogen storage tank 9, zeolite catalytic reactor 10, cyclone separator B 11, aromatic hydrocarbon collector 12, mixing agitator 13.

[0051] Such as figure 1 As shown, the device consis...

Abstract

The invention provides a device and a method for preparing bioaviation fuel. The device comprises a biomass ketonization reaction system, a carbon chain elongation reaction system, a zeolite catalytic reaction system and an alkane and arene mixing system, wherein the biomass ketonization reaction system is used for catalytically converting biomass into ketones and other monofunctional compounds in an orientated manner, and separating the ketones from the other monofunctional compounds; the carbon chain elongation reaction system is used for converting the ketone platform compounds produced by the biomass ketonization reaction system into alkanes and cycloalkanes through aldol condensation, hydrogenation isomerism and other reactions; the zeolite catalytic reaction system is used for converting the other monofunctional compounds produced by the biomass ketonization reaction system into arenes through zeolite catalytic conversion; the alkane and arene mixing system is used for mixing the alkanes, the cycloalkanes and the arenes according to a certain ratio to obtain the final aviation fuel. With the method, full-component utilization of the biomass can be achieved, the aviation fuel containing the straight-chain alkanes, the cycloalkanes, the arenes and many other components can be prepared, and the ratio of the components is controllable; a novel way of converting the biomass into the aviation fuel is provided.

Description

technical field [0001] The invention belongs to the technical field of biomass energy conversion and utilization, and specifically relates to a device and method for preparing aviation fuel by using biomass. The ketone platform compound obtains long-chain / cyclic alkanes and others through carbon chain growth and hydrogenation isomerization. Aromatic hydrocarbons are obtained by pyrolysis gas zeolite catalysis, and aviation fuel is obtained by mixing long-chain / cyclic alkanes and aromatic hydrocarbons. Background technique [0002] Aviation fuel is one of the most important transportation fuels, second only to gasoline and diesel in demand. Aviation fuel mainly includes two categories: aviation gasoline and aviation kerosene, which is a kind of fuel specially prepared for aircraft. In order to ensure the normal flight of jet aircraft at high altitude (above 10,000 meters), very strict standards have been set for aviation fuel. For example, aviation kerosene requires high cal...
