ZDOS catalyst Fcc catalyst

Brief introduction of product performance and technical characteristics:

ZDOS catalyst has excellent bottom oil cracking activity and excellent resistance to heavy metal pollution, can increase gasoline yield, and has a certain function of reducing gasoline olefin content and sulfur content. Its characteristics are:

In the carrier, a component that has an adsorption effect on macromolecular sulfides is introduced, and part of the sulfides is transferred to coke and dry gas.

By modifying the molecular sieve, the selective hydrogen transfer activity of the molecular sieve is strengthened to ensure that the catalyst has good coke selectivity and heavy metal pollution resistance.

The surface of the molecular sieve forms a stable L acid-base pair structure, which makes the catalyst have high desulfurization stability and hydrogen transfer activity. Different types of active centers are matched with each other to jointly complete the olefin and sulfur reduction process.

The support is activated to make the catalyst support have a certain cracking activity and larger pore distribution, so as to play a certain pre-cracking effect to increase the gasoline yield and reduce the concentration of olefins and sulfides.

It has high conversion rate of heavy oil and yield of light oil. It has no obvious influence on the distribution of other products. It has good resistance to heavy metals and is suitable for processing high nickel and high vanadium raw materials.
