Abstract
The invention relates to a complex catalyst for direct liquefaction of coal, and a preparation method thereof. The preparation method comprises the steps of simple-processing outdoor natural laterite-nickel ore which includes iron and nickel or more active metal components and is mainly produced in countries of Southeast Asia and the like near the equator, and grinding the laterite-nickel ore into fine powder to obtain the catalyst for direct liquefaction of the coal; or employing the natural laterite-nickel ore or other iron-containing ores as raw materials, loading chemicals or the ores comprising active components of transition metal elements of nickel, molybdenum, cobalt and the like on the iron ores via a manual method to form the complex catalyst for direct liquefaction of the coal. The preparation method by using the natural laterite-nickel ore as the catalyst or by using the laterite-nickel ore or other iron ores as raw materials and manually loading active metal components of cobalt, molybdenum and nickel to prepare the catalyst is simple and mature. By using the prepared complex catalyst for direct liquefaction of the coal to catalyze a direct liquefaction reaction of the coal, the catalyst has the characteristics of low catalyst consumption, high coal conversion rate, high product oil yield, etc.
Description
technical field [0001] The invention relates to a coal direct liquefaction catalyst in the field of coal chemical industry, in particular to a coal direct liquefaction catalyst containing at least two active components and a preparation method thereof. Background technique [0002] The sharp increase in world oil prices and oil consumption and the reduction of oil resources have forced the energy industry to consider developing alternatives that can replace petroleum fuels. Coal is one of the most abundant hydrocarbon resources on earth, and coal can be converted into liquid fuels through hydrogenation reactions. Coal direct liquefaction is a process in which coal, catalysts, and solvents are hydrogenated into liquid fuels and other chemicals in the reaction under high temperature and high pressure conditions. With the development of direct coal liquefaction technology, the reaction conditions of the new generation of direct coal liquefaction technology are more moderate, a...
