Multifunctional Enhanced Yield Increase Agent For Catalytic Cracking

Destroy the supramolecular structure

Residual oil is a colloidal dispersion system. The outer surface of the colloidal core is surrounded by a solvation layer. The polymer surface active substances in the catalytic enhancement enhancer can improve the dissolving capacity of the dispersion medium and reduce the radius of the colloidal core and the thickness of the solvation layer. , so that low molecular hydrocarbons are released from the solvation layer and undergo cracking reactions, thereby increasing the yield of light oil.

Pre-cracking of heavy hydrocarbon molecules

The active substances in the catalytic enhancement yield increase agent can pre-cracking heavy hydrocarbon molecules, overcoming the contradiction that heavy hydrocarbon molecules are easy to adsorb and difficult to react on the catalyst surface, increase the number of active centers on the catalyst surface, reduce the probability of the catalyst being contaminated by heavy metals, and improve the catalyst activity and resistance to heavy metal pollution. Reduce the generation of dry gas and coke and increase liquid recovery.

Polymerization inhibition mechanism

After adding the catalytic enhancement and yield increasing agent, a protective film is formed on the core of the complex structural unit, which can prevent the thermal condensation products of the coke from adsorbing on the catalyst surface. In this way, the precursors of the coke cannot contact the catalyst surface, but contact the catalyst. The surface is clean raw material without rapid coking components, so the amount of coking is reduced and the yield of light oil is increased.

Increase acid center

The rare earth elements contained in the catalytically enhanced yield increase agent have a preferential adsorption effect on alkali nitrogen in heavy oil, preventing the reduction of the acidic center of the catalyst, suppressing the amount of coke and oil slurry, and increasing the yield of light oil.

Inhibit thermal cracking reaction

The active substances contained in the catalytically enhanced yield increase agent can inhibit free radical chain reactions, prevent thermal cracking from generating dry gas and coke, and increase the yield of light oil.

Metal passivation reaction

The rare earth elements and organic antimony contained in the catalytic strengthening and yield increasing agent can simultaneously passivate the heavy metals vanadium, nickel, iron, copper, etc. deposited on the catalyst.
