price: contact company for price

Guard catalyst for environmental protecting

1. Product Description

This product is kind of catalyst covering &

bearing catalyst agent, being made using high

purity alumina as main material and special

composition. Special structure with slot

opening around increasing its surface area

and void fraction beside enough crushing

strength. Having 40-50% void fraction, this

product can effictivly filter impurity of oil

such as particle, colloid, asphaltene, heavy

metal etc.

Part of impurity can be strained out after

raw materials filter, while some particle and

ferric ion smaller than 25um still exist in

oil. Filling guard catalyst in top of reactor

can filter all of above impurity and protect

catalyst from coking, as well as extend

reactor’s cycle process.

Catalyst with different specs can be used

according to impurity content and size. Some

other activity material like Mo, Ni and Co

can be added depends on clients demand, in

order to protect catalyst from coking or


Application in petrochemical industries shows

that this catalyst also increace the flow

area of oil, reduce the system drop pressure

under 1 Mpa, improve the handling capacity of

the device by 26. 5%, and increase the

infiltration rate of catalytic diesel up to
