Abstract
Various conditions for the cracking of atmospheric residue from the Novokuibyshevsk Oil Refinery were considered and analyzed. Optimal conditions for the cracking of the atmospheric residue were found (a temperature of 450ºС and duration of 30 min), under which an additional 51.8 wt % of light fractions was formed due to the destruction of 31.3 wt % of resin–asphaltene components. The compaction products formed upon cracking were studied. Two fractions of asphaltenes (A1 and A2) from the feedstock and isolated from liquid cracking products were studied using structural group analysis. It was found that the duration of atmospheric residue cracking had an impact on the formation of secondary asphaltenes.
期刊介绍：
The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
