Problems solved by technology

The mixed feed is subjected to hydrogenation reaction at 5-20MPa, 380-460°C, and a light oil yield of more than 70% can be obtained under the condition of basically no coke formation, but the catalyst composition contains phosphorus, and the slurry In the bed residue hydrogenation unit, the amount used is relatively large, and it is difficult to meet the increasingly stringent energy-saving and environmental protection requirements in the process of production and use
[0005] The existing water-soluble organic molybdenum salts are mainly used in the lubrication field, but most of the developed water-soluble organic molybdenum salts have corrosion problems and environmental protection problems caused by the presence of compounds such as sulfur and phosphorus.

Abstract

The invention relates to an organic molybdenum salt and a preparation method thereof. The organic molybdenum salt is a molybdenum amine complex containing Mo<+6>, an acyl group bound with the molybdenum ion and an amine group combined with a hydrocarbon group in the acyl group, wherein molybdenum accounts for 10%-30% by mass of the organic molybdenum salt. The provided organic molybdenum salt is used as a catalyst precursor of a residual oil hydrogenation process, and has high hydrogenation conversion rate; meanwhile, the compound has excellent antiwear and antifriction properties and good metal corrosion inhibition performance, and can be used as a water-soluble lubricating oil additive. The preparation method of the water-soluble organic molybdenum salt is simple, the synthesis route isnon-toxic and environmentally friendly, and product separation is simple.

Description

technical field [0001] The invention relates to a molybdenum-containing organic compound and a preparation method thereof, more specifically, an organic molybdenum salt composition and a preparation method thereof. Background technique [0002] As the depth of oil extraction continues to increase, the crude oil extracted from oilfields is becoming increasingly heavy and inferior. This type of crude oil contains high sulfur, nitrogen, and metal content, and high carbon residue value. Conventional fixed-bed hydrogenation, catalytic It is difficult for cracking and other devices to process this type of crude oil. At the same time, people's demand for light oil products is increasing. In this case, the deep processing of heavy crude oil and the improvement of resource utilization have become an issue of increasing concern. Heavy oil processing technology is divided into two categories: decarburization and hydrogenation. In order to further increase the yield of light oil, hydro...
