Features of processing petroleum feedstocks with activating additives

The Effect of Oxygen-containing Additives in Feedstock on the Performance of the Catalytic Cracking Process

“…The best examples of this mechanism include studies where olefin concentrates [9], thermal cracking fractions with boiling temperature limits of 80-350 °C, and gasoline fractions of thermal origin were used as activating additives.…”

“…The effect of many known additives can be explained by the mechanism of colloid-chemical action [10]. Most additives based on aromatic hydrocarbon concentrates belong to this type.…”

“…During interphase transitions, the decrease in coke formation on the catalyst and the increase in the yield of the target products can be achieved by adding some surface-active substances and heteroatomic organic compounds to the composition of the raw materials of the process. For example, the researchers in a study [9] suggested using nonionic surfactants, such as oxyalkylated alkylphenol, as activating additives. Several organic compounds with heteroatoms can be used as additives, including petroleum naphthenic acids, humic acids obtained from the oxidation of gray coal, a cubic residue of methanol regeneration, and other compounds.…”
