[0037] The present invention provides a method of preparation of bioained coal components, including:

[0038] S1: The lignocellulose basedehyde compound and the carbonyl compound are hydroxal condensation reaction, resulting in c 8 ~ C 16 Long chain contains oxygen compound;

[0039] S2: Will C 8 ~ C 16 The long chain contains oxygenate in the first reaction zone that is sent to the reactor under a reactive solvent condition.

[0040] S3: Hydrogenated product is hydrode oxygen by hydrogenation by the second reaction zone of the reactor, resulting in c 8 ~ C 16 Long paraffin;

[0041] S4: C 8 ~ C 16 Long chain alkane is isomerized, and the bioained coal component oil is obtained after fractionation;

[0042] Wherein, the temperature of the first reaction zone is 50 ° C to 200 ° C, and the temperature of the second reaction zone is greater than the temperature of the first reaction zone.

[0043] According to the present invention, there is still a parallel reaction in the process of...

preparation example 1

[0075] This formulation is used to illustrate the preparation method of the hydrocarbon saturation catalyst of the present invention.

[0076] Tell 290G Ni (NO 3 ) 2 · 6h 2 O and 1600 g of silica sol (solid content of 30%) are dissolved in deionized water, configured to include 1.0 mol / L of sodium hydroxide solution B by Ni ion mean; to maintain a solution in agitation, The B solution was slowly added to the A solution until the system pH was 10.5. After the dropwise addition, stirring was continued for 1 h, then stop stirring, standing for aging 8 h. The precipitate was then filtered, washed to neutral, and the filter cake was dried at 110 ° C in the blast drying tank, and then baked at 500 ° C in the muffle furnace for 3 h.

Description

Technical field [0001] The present invention relates to the field of petrochemical technology, and more particularly to a bioained coal component oil and a preparation method thereof. Background technique [0002] In the context of oil crisis and greenhouse effects, as the only renewable energy-biomass that contains carbon sources is the most promising liquid fuel to produce oil resources in place of oil. In order to enable the transition from the fossil energy to the carbohydrate economy, the biomass is converted into a high value-added fuel and chemical, and the DUMESIC work team is based on the hydrolyzate hydrolyzate of the lignocellulose, and then prolongs carbon by hydroxal condensation reaction. Chain gave bioflacetone [4- (2-furanyl) -3-butene-2-ketone] and bioff acetone [1,5-double-(2-furanyl) -1,4-pentadiene -3-ketone], then hydrogenation deoxidation 8 Straight paraffins and c 13 Strained alkanes, final isomerization gave a qualified jet fuel component to achieve effici...
