Problems solved by technology

Supported catalysts and solid particle catalysts have poor dispersion performance; acidic catalysts are added in a large amount and are corrosive, which is not suitable for large-scale industrial production; oil-soluble catalysts have good dispersion effects and high activity, but the cost is high; while traditional water-soluble catalysts The cost is lower and the dispersion effect is better, but the multi-stage emulsification dispersion process is complex and the energy consumption is high in application

Abstract

The invention discloses a nickel-based high dispersion emulsion catalyst, a preparation method and application thereof. The preparation method comprises the steps of: (1) heating and dissolving a hydrophilic surfactant and a nickel salt in a 0.3-3 times mass of deionized water; (2) putting an oleophylic surfactant and wax oil into a condenser, performing heating to 50-80DEG C, and conducting stirring under a rotating speed of 1000-4000r / min; and (3) when the oil phase reaches a required temperature, adding the water phase slowly into the container, performing shearing dispersion under a constant temperature condition for 5~15min, and then conducting cooling to room temperature, thus obtaining the nickel-based high dispersion emulsion catalyst. The deionized water introduced into the catalyst prepared by the invention has no need for removal, the problem of large water removal energy consumption in a slurry bed hydrogenation process of the previous water-soluble catalysts can be avoided, the operation efficiency is improved, and the catalyst also has the advantages of good dispersion effect in raw materials, high hydrogenation activity, good coke suppression effect and high coal conversion rate.

Description

technical field [0001] The invention relates to the technical field of catalysts, in particular to a nickel-based highly dispersed emulsion catalyst and a preparation method and application thereof, which are suitable for hydrogenation co-refining of different coal types and heavy oil. Background technique [0002] my country's energy resource structure is characterized by poor oil, little gas, and rich coal. 70% of these primary energy sources are coal, and nearly 80% of them are converted into secondary energy sources such as electric energy and heat energy through direct combustion. The conversion efficiency is low, and there are serious ecological and environmental problems. In recent years, the world's petroleum resources tend to be heavy and inferior, and the proportion of heavy crude oil continues to increase. The petroleum industry and chemical industry increasingly need to develop heavy oil processing technology. Coal / heavy oil hydroprocessing co-smelting technology...
