1. High purity 2. Low price 3. Excellent quality Catalytic Cracking Of Multifunctional Passivation Agent

1,Application

   Inhibition of the catalytic cracking process of heavy metals such as nickel and vanadium on the catalyst poisoning effect, reduce the dry gas of hydrogen content and hydrogen / methane ratios, alleviate pressure machine load, improve the activity of the catalyst, the yield of light oil and device processing capacity. Increased device economic benefits.

2,Product performance

It can effectively restrain the metal nickel and vanadium metal dehydrogenation on FCC catalyst poisoning effect, reduce the dry gas of hydrogen content and hydrogen / methane ratios, alleviate pressure machine load, improve the activity and selectivity of the catalysts, enhance light oil yield and device processing capacity.

May according to the refinery catalyst nickel and vanadium content ratio of the different, adjust the multifunctional passivation of the effective component proportion, be "tailored, a multipurpose".

This series product is water soluble, slightly toxic. It’s convenient for transport, filling and cleaning. It’s flexible for adjustment of filling quantity.

3,Range of application

It can be used for high purity nickel, vanadium and blended residuum gas oil catalytic cracking of heavy oil catalytic cracking unit.

5,Instruction

   Multifunctional passivation agent industrial applications typically rapid filling and balance with two stages, but consider the passivation of nickel and vanadium in different passivation mechanism, raise two stages, nickel, vanadium blunt blunt two kinds of functional component ratio will be adjusted. Dull nickel effect mainly in dry gas or gas rich in hydrogen content changes to measure. Vanadium pollution on FCC catalyst, vanadium poisoning has been the catalyst produced irreversible inactivation, so in this portion of the catalyst is not replacement before the end, passivation passivation effect is not very clear, need longer continuous filling. Multifunctional passivation agent used to dry gas, hydrogen content in hydrogen / methane ratio and catalyst activity to improve the situation to measure.

6,Storage

   This product adopts plastic drums packaging, net weight 180 kg. In a cool ventilated place storage. The shelf-life is 18 months.
