Hydrodewaxing Chemical Catalyst Cylinder with Good Hydrogen Activation

Product Description

   Hydrodewaxing catalyst with good hydrogen activation and oxygen regeneration property

Dewaxing is a new technology of petroleum refining growing up in the 1970's. The basic principle of this technology is by the using of the catalyst which adopts ZSM-5 molecular sieve with special pore path as carrier to split the straight chain or the chain similar to straight chain hydrocarbons into gasoline fraction and a small amount of C3,C4,thus the melting point of the fractions in the rest part can be reduced remarkably. This process can be completed without or with very small amount of hydrogen consumption. So that it can be widely used for reducing the freezing point of kerosene and melting point of diesel, it can also be used in the dewaxing process for lube oil.
FRIPP began to research catalyst 3881 in 1982. In 1988,the enlarged industrial production of this catalyst was carried out successfully by the Catalyst Plant FPC CNPC and then put into regular industrial production. It has received the national patent,the medal of superior item of patent,and the second grade medal of scientific and technology progress from SINOPEC.
The feature of this achievement is that the ZSM-5 molecular sieve is synthesized by a non-amine synthesis technique directly. Therefore this catalyst is of low cost,low initial reaction temperature,and the running period of it is longer than the same kind of imported catalyst. This catalyst also possesses good hydrogen activation and oxygen regeneration property. It can be hydrogen activated and oxygen regenerated repeatedly for several times. It can meet the requirements of dewaxing technology for treating waxy heavy diesel.
