Embodiment 1
[0024]0.1 mol (27.8 g) of the ferrous sulfate dissolved in 500 ml of deionized water, 30 ° C After stirring, the ferrous sulfate solution was obtained, 0.02 mol (5.8) hexahydrate nickel, to give sulfuric acid of mixed metal ions The ferrous solution was added 0.5 mol (30.0 g) of urea, warmed to 90 ° C, remained continuously stirred for 6 h, resulting in a slurry, dried 6 hours at 60 ° C, resulting in a coal oil according to the present invention. Catalyst, recorded as CAT-1.
Embodiment 2
[0026]In Example 2, 0.24 mol (14.4 g) of urea was added, and the temperature was continuously stirred at 100 ° C, and the slurry was filtered, 6 hours at 100 ° C; Example 1 was identical to obtain a catalyst, which was recorded as CAT-2.
Embodiment 3
[0028]In Example 3, the ferrous sulfate was replaced with iron sulfate to iron sulfate hydrate, and nickel nitrate was replaced with nickel (1.5 g) of hexahydrate nitrate, and the remaining operation As in Example 1, a catalyst was obtained as CAT-3.

The invention relates to a preparation method and application of a coal and oil co-refining catalyst, and belongs to the technical field of material synthesis and application. The method comprises the following steps: adding urea into a ferric salt solution mixed with auxiliary metal ions, and stirring and reacting at 70-100 DEG C for 6-10 hours to obtain slurry; and filtering, and drying the filter residue at 20-100 DEG C to obtain the catalyst. The auxiliary metal ions are more than one selected from cobalt, nickel, molybdenum, copper and aluminum. When coal and oilare co-refined, the catalyst and sulfur powder are added into a coal and oil mixed slurry, and vulcanized at 90-150 DEG C to obtain the vulcanized catalyst. According to the method, urea is used as a precipitant, after urea is dissolved, ammonia can be slowly and uniformly released in a solution by controlling the decomposition temperature of urea, and iron ions and auxiliary metal ions are uniformly and slowly co-precipitated into nanoparticles; meanwhile, excessive urea is added, so that the specific surface area and the pore volume of the catalyst can be improved in the later use process.
Description
Technical field[0001]The present invention relates to the preparation method and application of kerosene common refining catalysts, belonging to material synthesis and application technology.Background technique[0002]As the rapid development of the economy and the increasing people's living standards are increasing, my country's demand for energy is getting bigger and bigger. Although the dominance of fossil energy is not replaced 2050, it is possible to enhance environmental management and improve energy utilization efficiency, it is foreseen that my country will become more and more strictly controlled in a single energy consumption in China. On the other hand, in the crude oil of most important oil fields in my country, the reduced pressure residue is high,>500 ° C yield is generally 40% to 50%. Coal / heavy oil (or residual) Hydrogenation is one of the most effective techniques that currently treat heavy oil (or residual) hydrogenation and coal liquefaction.[0003]The catalyst...
