CATALYST COMPOSITION, PREPARATION METHOD THEREFOR AND USE THEREOF

WIPO Patent Application WO/2022/247010

A1

A catalyst composition, a preparation method therefor and the use thereof. The present invention belongs to the technical field of viscosity reduction exploitation of heavy oil. The catalyst composition comprises the following components in percentages by mass: 1-5 wt% of free N-heterocyclic carbene, 1-2 wt% of N-heterocyclic carbene iron, 15-30 wt% of a phase transfer catalyst, 1-5 wt% of a hydrogen donor, 5-10 wt% of phosphoric acid, and 0.5-1 wt% of an emulsifier, with the balance being a solvent, adding up to 100%. The method for preparing the catalyst composition comprises: mixing free N-heterocyclic carbene and N-heterocyclic carbene iron with a solvent, adding a phase transfer catalyst and a hydrogen donor, mixing same, adding phosphoric acid and an emulsifier, and mixing same to obtain the catalyst composition. The catalyst composition or the catalyst composition prepared by means of the preparation method can be applied to the treatment of a heavy oil, and rapid and efficient viscosity reduction of heavy oil can be realized with only relatively small amounts of N-heterocyclic carbene iron and free N-heterocyclic carbene.
