Jiangsu Jingjiang Catalyst Co., Ltd.--Series nickel hydrogenation catalysts

Uses & characteristics	sNickel-Aluminiam is made from pure Nickel, Aluminium (or Cr,Fe,Ti,Mu,Co,Mo et al added) which fused at high temperature, and smeshed to particle(20~30 mesh), and has poly-hole sketetal nickel stucture after alkalization. It appearites high hydrogenation, dehydrogenation activities. Bucause of the high activity of skeletal Nickel, simple preparation, lower price than similar kind of catalysts, good thermal conductivity, high mechanical strenght and insensity to poison, it is broadly used. Nickel catalyst is mainly used in the process of hydrogenation of variety of unsaturated hydrocarbon in the liquid-solid phase reation condition, it is also used in the dehydrogenation, desulfurixation, dechlornation processes. It can not only be used in mainly catalyst process, but also used in the prerefining of the grass product of variety of unsaturated hydrocarbon. It is widely used in petrolium, chemical, pharmaceuitcal, perfume,synthetic fibre industry et al.Our products has been used in hundreds of plants. Nickel Aluminium alloy powder.
Physical property	It apperas black or greyish black amorphous partical. The partical size is from 20 to 300 mesh, other sizes can be provided according to the clients requirements. The bulk density varies in accoracne with the mixture ratio of Nickle and Aluminium, usually 2.5~4.0kg/L.
Chemical Compositions constituents	Nickel 30~50%, the rest is Aluninium, other small amount elements, such as Fe,Cr,Ti,Mo,Co,and so on, can be added according to the actual reation condition of clients.
Storage, package and others	a Nickel-Aluminium alloy powder is enclosed in plastic bag,tightly tied, and put in metal bucket with lid. Net weight is 50kg/bucket. b Nickel -ALuminium alloy powder should be stored in a shady, cool and dry storehouse.
Skeletal Nickel Catalyst	1. Skeletal Nicked Catalyst is abbreviatly named Raney-Ni. 2. Technical requirement of skeletal Nickel Oxygen consumption>90ml/g 3. Storage,Package and others: a. Activated Raney Ni will cause vigorous oxidtion, even ignition on contact with oxygen in air, therefore the catalyst must be prevented from oxygen, usually can be sealed by water. b. Skeletal Nickel catalyst is finned in high-strength plastic bucket.50kg/bucket(dry basis),or packed according to the requirements of clients. Because of the very little oxgen solved in water.The existence of active nickel and the reaciton of water and some impurities, the existence of active nickel and the reaction of water and some impurities, the acitiviay of the long-term stored catalyst may decreased slowly with gas release.In order not increase the pressure inside the bucket, which may cause the bucket crack, the lid should not be sealed tightly, or little holes be punened in to release the gas and decrease the pressure. c. The activity of long-term stored catalyst will decrease slowly,thus it can not be stored over 2 years generally. d. sulfue,chloride, and other elements may cause catalyst poisoning.Therefore contact with this elements should be avoided in use and storage.It is difficult for the deactived and poisoned catalyst to return to normal activity by reactivivation generally. e. The product is harzard material, so it should be transported by speical rehiche.
