Embodiment 1

[0062] Weigh 2.5002g of sodium molybdate dihydrate into a round bottom flask, add 1.0013g of thiourea, 0.4993g of manganese acetate tetrahydrate and 100mL of paraffin oil; heat and reflux in an oil bath at 240°C for 120 minutes; after the reaction is complete, turn off the power, Naturally cooled to room temperature; the reaction mixture was suction filtered to obtain a filter cake, which was vacuum-dried at 45°C and ground to obtain 1.8200 g of a solid whose thermogravimetric analysis curve was shown in the attached figure 2 shown.

Embodiment 2

[0064] Weigh 2.4998g of sodium molybdate dihydrate into a round bottom flask, add 0.9991g of thiourea, 0.5008g of cobalt acetate tetrahydrate and 100mL of paraffin oil; heat and reflux in an oil bath at 240°C for 120 minutes; after the reaction is complete, turn off the power, Naturally cooled to room temperature; the reaction mixture was suction-filtered to obtain a filter cake, which was vacuum-dried at 45° C. and ground to obtain 2.3462 g of a solid, whose thermogravimetric analysis curve was as attached image 3 shown.

Embodiment 3

[0066] Weigh 2.5001g of sodium molybdate dihydrate into a round bottom flask, add 0.9999g of thiourea, 0.5000g of ferrous acetate and 100mL of paraffin oil; heat and reflux in an oil bath at 240°C for 120 minutes; after the reaction is complete, turn off the power and let it cool naturally to room temperature; the reaction mixture was suction-filtered to obtain a filter cake, which was vacuum-dried at 45° C. and ground to obtain 2.6099 g of a solid whose thermogravimetric analysis curve was as attached Figure 4 shown.

Abstract

The invention relates to a magnetic MoS applied to viscous reduction of heavy oil 2 Nanoparticle catalyst and preparation method thereof, comprising steps as follows: (1) mixing molybdenum source, sulfur source, magnetic source and non-polar organic solvent, heating and reflux reaction, and solid-liquid separation to obtain magnetic MoS 2 Nanoparticle solid; (2) the magnetic MoS 2 Nanoparticles undergo heat treatment to obtain magnetic MoS 2 nanoparticle catalyst. The raw material preparation method involved in the present invention is simple, the product has high activity, high selectivity and high stability, and can utilize its magnetic recycling, solves the problem of traditional MoS 2 The preparation cost is high, and it is difficult to recycle after the reaction, which leads to the problem of huge consumption in practical application, which has important practical application significance.

Description

technical field [0001] The invention relates to a magnetic MoS 2 The nano particle catalyst and its preparation method and application belong to the technical field of catalysts. Background technique [0002] Heavy oil is an unconventional hydrocarbon resource with great potential. China is one of the four major heavy oil countries in the world, with extremely rich heavy oil resources. How to efficiently develop and utilize heavy oil resources has become an urgent problem in the petroleum industry. In terms of heavy oil exploitation, several methods have been developed at home and abroad in the past 20 years, such as thermal recovery (burning oil layer, electric heating, steam huff and puff and steam flooding), biodegradation, physical recovery (magnetic decondensation and viscosity reduction, acoustic oil recovery, water Hirai, etc.) etc. Among them, using catalysts to chemically reduce the viscosity of crude oil underground is an effective way. On the other hand, even...
