摘要

We have studied the preparation of nanosized catalytic metal complexes in hydrocarbon media and their effect on the thermal cracking of heavy hydrocarbons. The major focus was on clusters of transition metals such as zinc and their stability and activity at high temperatures. The importance of nanocatalysts as a promising alternative to catalysts used in classical cracking processes is considered. Ultrafine nanosuspensions of metals such as nickel and zinc were obtained in vacuum gas oils. The formation and stability of these nanoparticles were studied under various temperature conditions. The nanoparticles were found to be formed in boiling gas oil and remain stable at temperatures above 365°C. These results suggest the possible use of these nanocatalysts in the refining of heavy hydrocarbons.
