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.

常压渣油裂解过程中沥青质A1和A2的转化

摘要

考虑并分析了新伊比雪夫斯克炼油厂常压渣油裂解的各种条件。找到了常压渣油裂解的最佳条件（温度为 450°С，持续时间为 30 分钟），在此条件下，由于 31.3 wt% 的树脂沥青质组分被破坏，额外形成了 51.8 wt% 的轻质馏分。研究了开裂时形成的压实产物。使用结构基团分析研究了来自原料和从液体裂化产物中分离出的两种沥青质馏分（A1 和 A2）。研究发现，常压渣油裂解时间对次生沥青质的形成有影响。
