Abstract

The application discloses a nickel-based catalyst and its preparation method and application. The nickel-based catalyst includes a carrier, and the surface of the carrier is loaded with active components; the carrier is a metal oxide; the metal oxide has the general formula : A (1‑x) B x o 2 , wherein, A is selected from transition metal elements, and B is selected from lanthanide elements; the active component includes at least Ni. The nickel-based catalyst of the present application is used to reduce the viscosity of heavy oil, and the viscosity of crude oil with a kinetic viscosity of not less than 1000 mPa·s after degassing and dehydration at 50°C can be reduced by at least 65% without additional hydrogen donor or oxygen donor %, and the technical route of the present invention does not need other additives, realizes the purpose of reducing viscosity in a short time, at a lower temperature and pressure, is convenient to operate, and is suitable for large-scale industrial applications.

Description

technical field [0001] The application relates to a heavy oil modified nickel-based catalyst and its preparation method and application, belonging to the technical field of oil field chemistry. Background technique [0002] As an important unconventional crude oil resource in the world, heavy oil is an important resource to ensure my country's energy security and major engineering needs. With the continuous increase of oil demand and the gradual reduction of conventional crude oil resources, heavy oil has great development value, and the output of heavy oil in world oil exploitation is also gradually increasing. However, the high content of colloids and asphaltenes in heavy oil leads to high viscosity and freezing point, which makes the exploitation, gathering and refining of heavy oil more difficult. [0003] Due to the high viscosity of heavy oil, the fluidity of heavy oil becomes poor during production and gathering and transportation, the flow resistance increases, and ...
