Feed ratio of residue to wax oil is 1:1; the boiling range of the light fraction is quite high and its color is dark

Feed ratio of residue wax oil is 1:1; the distillation range of the light fraction is quite wide, and its color is dark. I’m not sure what the reason for this is
The residue and wax oil mixture contains a high proportion of heavy components as well as unstable impurities such as asphaltenes and resins; these components tend to undergo cracking during the distillation process, causing the low-boiling-point fractions to turn dark in color. It is recommended to check and optimize the operating conditions of the distillation unit, such as adjusting the operating temperature and pressure of the distillation column, in order to obtain cleaner light oil products. It is also possible to consider more thorough pretreatment of the raw materials, such as using appropriate dedusting techniques or additives to improve the quality of the distillate products. .

It’s mainly due to the shallow depth of reaction
