Abstract

In this work, various conditions for cracking the atmospheric residue of the Novokuibyshevsk oil refinery are considered and analyzed. The optimal conditions for cracking the atmospheric residue have been established as a temperature of 450°С and a duration of 30 minutes. These conditions result in an additional 51.8 wt % of light fractions due to the destruction of 31.3 wt % of resin-asphaltene components. The study also examines the compaction products formed during cracking. The study analyzed two fractions of asphaltenes (A1 and A2) isolated from liquid cracking products using the method of structural group analysis. It was found that the duration of atmospheric cracking had an impact on the formation of secondary asphaltenes.
