AI Technical Summary

Technical Problem

Existing slurry-bed hydrogenation catalysts require a large loading of active metals, resulting in high costs and low catalytic efficiency, making it difficult to efficiently utilize inferior heavy oils such as catalytic slurry.

Method used

Using iron-based metallurgical powder with a particle size of 200-250 mesh and a particle size dispersion of less than 10% as a carrier, a slurry bed hydrogenation catalyst was prepared by impregnating an active metal solution, adding ammonia water to form a metal crystal precipitate, and then calcining it. This catalyst is used to catalyze the slurry bed hydrogenation reaction of oil slurry.

Benefits of technology

With a relatively small active metal loading, uniform distribution of catalytic efficiency and high catalytic effect are achieved, reducing catalyst cost, improving the conversion rate and economy of inferior heavy oil, and producing clean fuel oil products.
