Problems solved by technology

However, it is still not easy to directly prepare metal catalysts by using metal carbonyls or their supports, because the volatilization temperature of most metal carbonyls is much lower than the decomposition temperature.

Abstract

A preparation method of a supported ultrafine amorphous metal nickel catalyst for realizing catalytic full hydrogenation of an aromatic ring comprises: sequentially adding 10-1000 milliliters of organic solvent, 1-40g of a catalyst carrier and 1-100 milliliters of nickel carbonyl into a high-pressure reaction kettle of which a cover is opened, and closing the cover; enabling high-purity nitrogen gas to slowly flow in through a gas inlet and then flow out through a gas outlet, slowly introducing high-purity hydrogen gas into the high-pressure reaction kettle to 2-8MPa through the gas inlet, and then closing a valve of the gas inlet; starting a motor to drive a magnetic stirrer, and sufficiently stirring and mixing at room temperature; and then, quickly heating while fast stirring to raise temperature to 70°C-280°C, keeping the temperature, and enabling the nickel carbonyl adsorbed on a surface of the carrier to be resolved into an elementary nickel substance and attached onto the surface of the carrier, thus preparing the supported ultrafine amorphous metal nickel catalyst for realizing catalytic full hydrogenation of an aromatic ring.

Description

technical field [0001] The content of the present invention relates to a preparation method of a catalytic aromatic ring full hydrogenation catalyst, especially a preparation method of a catalytic aromatic ring full hydrogenation supported ultrafine amorphous metal nickel catalyst. Background technique [0002] Owing to the shortage of petroleum and the increasingly heavy and inferior quality of refined petroleum, the technology of direct coal liquefaction and indirect liquefaction of coal to produce liquid fuels has been rapidly progressing and developing in China in recent years. How to solve the partial product obtained from direct coal liquefaction-high-concentration aromatics deep hydrogenation conversion into light components; how to solve the by-product obtained in the process of coal indirect liquefaction to produce ethanol gasoline-heavy benzene is effectively hydrogenated into high-quality liquid cleansing Fuel; How to solve a series of problems such as reducing th...
