Iron ore-containing heavy oil hydrogenation catalyst, and preparation method and application thereof

Abstract

The invention relates to an iron ore-containing heavy oil hydrogenation catalyst, and a preparation method and an application thereof. The heavy oil hydrogenation catalyst is composed by iron ore-containing powder and a dispersion medium. Based on the catalyst, the mass percentage of the iron ore-containing superfine powder is 5-70%; and the dispersion medium comprises the following components of, based on the dispersion medium, 80-99 wt% of a base oil, 0.05-10 wt% of a surfactant and 0.05-10 wt% of a solid thickening rheological agent, wherein the base oil is a distillate oil with a boiling point ranging from 220 DEG C to 550 DEG C. The heavy oil hydrogenation catalyst obtained by the invention has not only high catalytically active solid content but also good mixed ability with a raw oil of the heavy oil, and has good catalytic effect in heavy oil hydrocracking or hydro-upgrading of a suspended bed or a slurry bed.

Description

technical field [0001] The invention relates to a heavy oil hydrogenation catalyst. More specifically, it is a catalyst for iron-containing ore powder used for hydrogenation of heavy oil, as well as the preparation method and application of the catalyst. Background technique [0002] With the gradual scarcity of conventional oil resources, the proportion of heavy oil, especially low-quality heavy oil, in the total oil is increasing. How to efficiently convert heavy oil has become a huge challenge in the energy field. The heavy oil referred to above includes asphalt, oil sands, shale oil, residual oil with a boiling point higher than 524°C, etc. Its characteristics are: high asphaltene and residual carbon content, high metal nickel and vanadium content, the total content is generally not less than 200μg / g, high S and N compound content, and high apparent viscosity at normal temperature and pressure. Inferior heavy oil is prone to clogging pipelines and reactors and producin...
