WNZS-1 Hydrofining Catalyst
1. Characteristics:
WNZS-1 Hydrofining Catalyst takes promoted alumina as carrier material with such metal components and auxiliaries as tungsten and nickel, featuring good activity of HDS,HDN aromatics saturation and hydrodecolloid in low pressure, and having high resistance to compression and attrition. it can be reused after regeneration. This catalyst contains no easily lapsed active components, so it won't corrode equipment and have good activity stability.
Application:
WNZS-1 Hydrofining Catalyst can be used in the hydrofining of poor secondary processed gasoline and diesel. Under medium and low operating pressure, catalyst WNZS-1does very well in hydrofining all sorts of FCC diesel and coked diesel to produce high quality diesel oil with low sulphur and low aromatics.

SCHENDLY Industry: A professional manufacture for Catalyst Carriers.
Carriers are the breath of life to the catalysts. The appearance, components, and properties of carriers have significant influence the performance of catalysts. Schendly designs the most suitable carriers for the catalysts to maximize the efficiency and service life.
We use magnesia, titanium dioxide and composit...E
Metallic oxide as the raw materials to supply extruded, sphere,
Ring and cylinder, cellular texture and unique shape carriers for
Special demands of our customers. We also work collaboratively
With famous institutions, devoting our ideas and passions to
Create new carriers all the time.
We produce various types of catalyst carriers including extruded catalyst carriers, sphere shapes carriers, cylinder carriers, and cellular texture carriers.
The appearance includes solid extrudates, trifolium extrudates, quadrifoil extrudates, papilionaceous extrudates, micro-sphere, standard sphere, oval sphere, porous-sphere, ribbed sphere, rectanglar, circular, oval, etc.
The main physical properties are as following:
Bulk density: 0.45-0.8 g/cm3;
Pore volume: 0.5-0.8 cm3/g;
Specific surface area: 150-350 m2/g
