Crude oil residue
Thread Content
What is the typical residue content in crude oil used for conventional catalytic cracking in various plants? Let’s all talk about it.
Reply to 1# Mountain bamboo shoots are generally around 5–6.
The carbon residue of feed oil for fluidized catalytic cracking is generally 5-6%, while that of feed oil for heavy oil catalytic cracking does not exceed 8%.
The smaller, the better; values greater than 5 affect the production cycle and yield
5-6%; it’s not the case that the lower, the better.
The wax content is usually around 0.1%, but if a small amount of heavy oil is blended in, it’s necessary to reduce the amount used. What determines the proportion of heavy oil blended in? It’s not just the residue content, right?
Residual carbon is a tendency indicator used to measure the tendency of catalytic cracking feedstocks to form non-catalytic coke, and it is widely used. The residue value of distillate oil is very low, generally not exceeding 0.2%, and its contents of gum and asphaltenes are also minimal. Residual carbon content in residue is high, ranging from 5% to 27%, and its contents of asphaltene and gum are also high. Residual carbon is generally formed by the condensation of polycyclic aromatics, and residue oil contains not only a large amount of aromatics. There is also a large amount of gum and asphaltenes, and these gum and asphaltenes contain plenty of polycyclic aromatic hydrocarbons as well. The residual carbon analyzed in the laboratory is the precursor substance of raw coke.
