DAEON513 non antimony based metal passivating agent is a water-soluble metal passivating agent that can simultaneously dissolve vanadium and nickel. It is used for FCC devices to inhibit the pollution of heavy metals, nickel and vanadium on FCC catalysts. The effective component can be adjusted according to the content of nickel and vanadium in the raw material and the pollution level of the catalyst, so as to control the nickel and vanadium pollution of the FCC catalyst more reasonably and effectively. Improve and improve the activity and selectivity of the catalyst, increase the overall efficiency of the device.
Because the passivating agent does not contain antimony compounds, the harm of the traditional antimony containing passivation material to the environment and human health is greatly reduced.
DAEON513 non antimony type metal passivation agent should be added to the point after all heaters, from the riser pipe 4m outside the raw tubing line.
Can be diluted with water before filling into 20-50% solution, deposition amount of raw materials in Ni, generally considered the content of V and Ni, V equilibrium catalyst and catalyst on the non balance, the general activity ratio of 0.5-0.7 PN:NI sb. The recommended dosage is 100-200ppm.
