Problems solved by technology

Compared with the cracking reaction method, although this method lowers the reaction temperature to a certain extent, the reaction still needs to be carried out at a high temperature of 350-600 ° C. Therefore, the reaction temperature is too high, which increases the cost.

preparation example Construction

[0023] The invention discloses a method for preparing hydrocarbon fuel, which comprises the following steps:

[0024] In the presence of hydrogen, the oil and the supported ruthenium-based catalyst are dissolved in an organic solvent, and the oil is subjected to a hydrodeoxygenation reaction in a closed reaction vessel to obtain hydrocarbon fuels. The supported ruthenium-based catalyst is TiO 2 as a catalyst carrier.

[0025] In the present invention, the oil is vegetable oil and / or animal oil, more preferably, one or more selected from the following ingredients: rapeseed oil, rice bran oil, corn oil, soybean oil, sunflower oil, hemp seed oil, Olive oil, coconut oil, peanut oil, mustard oil, cottonseed oil, tallow, lard, whale oil, and fish oil. The main components of the above oils are mixed fatty acid triglycerides, and there are also very small amounts of triglycerides, such as various fat-soluble celluloses (VA, VD, VE and VK), pigments (chlorophyll, carotenoids, etc.) )...

Embodiment 1

[0037] Ruthenium chloride is placed in water, stirred for a certain period of time so that the ruthenium chloride is fully dispersed, and an aqueous ruthenium chloride solution is obtained;

[0038] Calcined pretreated TiO 2 The carrier is impregnated into the ruthenium chloride aqueous solution, fully impregnated at room temperature overnight, then dried at 60°C, and finally calcined in a muffle furnace at 300°C to obtain a supported ruthenium-based catalyst.

Embodiment 2

[0040] Add ethyl stearate and the supported ruthenium-based catalyst prepared by embodiment 1 in the 50ml reactor, the consumption of this loaded ruthenium-based catalyst is 10% of raw material, after dissolving with n-hexane, pour into described reactor 3.0 MPa hydrogen gas was introduced, the reaction temperature was 200° C., the liquid product was obtained after reacting for 17 hours and then cooled to room temperature, and the yield of hydrocarbon fuel was greater than 95%.

[0041] The liquid product prepared by the present embodiment is analyzed by gas chromatography, and the results are as follows: figure 1 As can be seen from the figure, the liquid product is mainly hydrocarbons of C17 and C18, without the peak of ethyl stearate, which proves that the reaction is relatively complete.

Abstract

The invention discloses a preparation method of a hydrocarbon fuel. The method comprises the following steps of: dissolving grease and a loaded ruthenium-based catalyst into an organic solvent in the presence of hydrogen; and undergoing a hydrodeoxygenation reaction on the grease in an enclosed reaction container to obtain the hydrocarbon fuel, wherein TiO2 is taken as a catalyst carrier in the loaded ruthenium-based catalyst. Compared with the prior art, the method has the advantages that: the loaded ruthenium-based catalyst in which the TiO2 is taken as the catalyst carrier has high catalytic action; and under the synergic action of ruthenium and the carrier TiO2, the reaction temperature of the hydrodeoxygenation reaction of the grease is lowered, the hydrodeoxygenation reaction of the grease is realized under a relatively mild condition, the transformation of alcohol serving as an intermediate product is promoted, and the yield of the hydrocarbon fuel is further increased. As proved by an experimental result, the reaction temperature of the preparation method provided by the invention is 200-250 DEG C, and the yield of the hydrocarbon fuel is over 90 percent.

Description

technical field [0001] The invention relates to the technical field of renewable energy preparation, and more specifically, relates to a preparation method of hydrocarbon fuel. Background technique [0002] With the rapid development of industrial technology, energy consumption has increased sharply, and the problems of energy security and environmental pollution have become increasingly prominent. Relevant monitoring agencies believe that according to the current speed of use and exploitation, petroleum energy may be exhausted within 50 years. At the same time, with the consumption of petroleum energy, environmental problems have become increasingly prominent. For example, air pollution caused by excessive emissions of vehicle exhaust is the main cause of global warming, melting glaciers, acid rain, climate change and many major diseases of modern humans. Therefore, seeking alternative green renewable energy has become a major problem to be solved urgently for mankind. [...
