Embodiment

[0030] 1. Preparation of catalyst:

[0031] 1) Acid catalyst: Nafion, Amberlyst resin solid acid, FeCl 3 , ZnCl 2 , SnCl 4 、TiCl 4 , FeCl 3 , trifluoromethanesulfonic acid, sulfuric acid and hydrochloric acid are commercial catalyst products purchased directly.

[0032] 2) Preparation of hydrodeoxygenation catalyst: prepare palladium chloride, ruthenium chloride, chloroplatinic acid, and chloroiridic acid with a mass ratio of 10%, and add one or two or more metal salt solutions in nitric acid according to the metering ratio. (250mL33% nitric acid solution was added to 50g of activated carbon, treated in a water bath at 80°C for 12 hours, filtered, washed with deionized water to neutrality, and then dried in an oven at 120°C for 12 hours) with a medium volume of activated carbon impregnated, then static Set for 2h, dry overnight at 120°C, reduce with hydrogen at 500°C for 2h, and pass 1% O after the temperature drops to room temperature 2 Passivation can prepare monometal...

Abstract

The invention discloses a preparation method of aviation kerosene or diesel oil, and relates to a new path for compounding liquid-state chain hydrocarbon fuel based on a raw material of lignocelluloses platform chemical compound. The preparation method is divided into three parts: (1) preparing 4,4-bis(5-methyl furan-2-furyl) pentanoic acid from a dehydrated product-angelica lactone of levulinic acid in an acid catalyst and 2-methyl furan through an acid catalytic alkylation reaction; (2) hydrogenating the 4,4-bis(5-methyl-2-furyl) pentanoic acid, effectively removing C-C double bonds and C-H double bonds in the 4,4-bis(5-methyl-2-furyl) pentanoic acid, and preparing a saturated organic compound containing oxygen; (3) carrying out hydrodeoxygenation on a hydrogenated alkylate by adopting a metal-carbon catalyst, thus obtaining biomass aviation kerosene or high-quality diesel oil of which the carbon chain length is 8 to 15.

Description

technical field [0001] The invention relates to a new route for obtaining platform compounds to synthesize liquid chain hydrocarbon fuels based on lignocellulose as a raw material. The method of the present invention is divided into three parts: 1) the dehydration product of levulinic acid-angelica lactone is reacted by acid-catalyzed alkylation with 2-methylfuran on an acid catalyst (such as Lewis acid, proton acid, solid acid, etc.) Preparation of 4,4-bis(5-methylfuran-2-yl)pentanoic acid; 2) By hydrogenating 4,4-bis(5-methylfuran-2-yl)pentanoic acid, effectively remove the carbon-carbon double bond and carbon-oxygen double bond to prepare saturated oxygen-containing organic compound; 3) by using metal-carbon catalyst to hydrodeoxygenate the alkylation product after hydrogenation, so as to obtain a carbon chain length of 8 Biomass aviation kerosene or high-quality diesel between 15 and 15. Background technique [0002] Aviation kerosene is a kind of fuel specially prepar...
