FCC Metal Passivator Nickel And Vanadium No Corrosion

FCC Metal Passivator Efficiently Passivates Various Metal Impurities Such As Nickel And Vanadium No Corrosion

Product description

During the catalytic cracking production process, heavy metal elements (especially Ni, V, etc.) in the feed oil are deposited on the catalyst surface, causing catalyst poisoning and deactivation.As a result, the catalyst activity decreases, the selectivity becomes worse, the product coke and dry gas yields increase, and the light oil yield decreases.

The working principle of FCC metal passivator is based on the fact that the effective components of the passivator are deposited on the surface of the catalyst together with the raw oil and interact with metal nickel, vanadium, etc., either to form metal salts, or to cover the metal in the form of a film.The result is to change the dispersion state and existence form of polluting metals, transforming them into stable, non-polluting active components, inhibiting their damage to the catalyst activity and selectivity, thereby increasing the output rate.

FCC metal passivator is an important catalyst which widely used in the petrochemical industry. It has many unique properties that make it play an important role in refineries and chemical plants.

First, FCC metal passivator have excellent catalytic activity.It can promote the catalytic cracking reaction and convert heavy petroleum fractions into high value-added light products, such as gasoline, diesel and liquefied petroleum gas.This highly active catalyst enables efficient reactions at relatively low temperatures and pressures, saving energy and costs.

Secondly, FCC metal passivator have good stability and long life.Under high temperature and high pressure conditions, the catalyst can maintain its catalytic activity and still has good stability after multiple cycles.This long-life feature makes FCC metal passivator an important catalyst choice in the petroleum refining process, which can reduce the frequency of maintenance and replacement of catalysts and improve production efficiency and economic benefits.

In addition, FCC metal passivator also have good selectivity and high yields.It can achieve selective production of specific products by adjusting physical and chemical properties, such as adjusting the ratio of gasoline and diesel. The high selectivity and high yield of the catalyst can meet the market demand for specific products and improve the quality of the product to a certain extent.

Finally, FCC metal passivator have lower environmental pollution and hazards.Compared with traditional acidic catalysts, the wastewater and exhaust gas generated by metal passivators during the cracking process contain fewer harmful substances and cause less environmental pollution.In addition, metal passivators will not cause safety risks such as flammability and explosion, and can ensure the stability and safety of the production process.

In summary, FCC metal passivator play an important role in the petrochemical industry due to their excellent catalytic activity, stability and long life, good selectivity and high yield, as well as low environmental pollution and danger. Its application effectively improves the production efficiency and economic benefits of refineries and chemical plants, making a positive contribution to the sustainable development of society.

Instructions:

1. The process of using passivation agent should be based on the vanadium and nickel content of the raw oil and the deposition amount of nickel and vanadium on the catalyst, and then calculate the required amount of passivation agent. Factors such as the properties of the feed oil and catalyst and operating conditions must be considered when determining the final addition amount. The only criterion is that the hydrogen content in dry gas decreases and the light oil yield increases. It is generally believed that the antimony to nickel ratio on the catalyst is 0.25-0.5.

• This product can be added directly, or it can be diluted with 1:1 water and injected into the catalytic raw oil pipeline with a metering pump to mix with the raw materials.

Precautions:

1. When the metal passivator leaves the factory, it is prepared according to product standards, and users can dilute it as needed. However, it should be noted that the antimony content will be reduced accordingly after dilution.

2. The passivating agent should be placed in a cool, sun-proof and rain-proof warehouse to avoid collision and leakage during transportation.

3. The passivating agent addition process should be as continuous and uniform as possible, and avoid adding and stopping at times to avoid affecting the use effect.

4. The effect of the passivator and the optimal addition amount are determined based on the decrease in hydrogen content in the dry gas. However, this is not the only criterion and should be determined based on factors such as catalyst, variety, and operating conditions.

5. When using passivating agent, do not let it come into contact with the skin, and avoid splashing into the eyes and respiratory tract. If the above situation occurs, rinse immediately with plenty of water.

6. It is best not to mix passivators. Since various factories use different raw materials and produce a wide variety of passivators, sometimes mixed use will not only have synergistic effect, but may even cause serious consequences due to reactions.
