characteristics:
It takes modified alumina as supporter, carrying molybdenum, nickel, cobalt components and has the property of deep HDN,HDS and alkene saturation. The catalyst has outstanding compression resistance and abrasive resistance, can be regenerated by nitrogen -air or water vapor-air.
Application: It is widely used to hydrotreat light straight distilled oil and secondary processed gasoline for raw material of platiform..
