Analysis of the four components of catalytic raw materials
Thread Content
The catalytic mixed feedstock (refined residue + atmospheric wax oil) consists of four components: saturated fraction: 60%, aromatic fraction: 28%, asphaltenes: 0.5%, and char: 11.5%. What can be inferred from the analysis of these four components? I hope to receive guidance from all the teachers. Thank you!
The four-component separation method is primarily used to study the chemical composition of residue oil (especially vacuum residue), that is, to separate it into saturated components, aromatic components, resins, and asphaltenes. The method involves first precipitating the asphaltenes in the raw material using n-heptane, and then carrying out quantification ； The soluble fraction of n-heptane was then washed with various solvents on a neutral alumina adsorption column with 1% water content, thereby separating the saturated fraction, the aromatic fraction, and the gums.

It seems a bit high; I guess the density of this material is over 900. Saturated hydrocarbons have the best cracking properties, and a 60% content is quite good
Teacher, can we determine the product distribution just by looking at the four components?
