characteristics: It takes modified alumina as carrier ,carrying such active components as tungsten and nickel and special promoter, featuring high activity in low temperature, good stability, good compression resistance and abrasive resistance, and easy loading and unloading, etc. it can be reused after regeneration.
Application：It is mainly used to produce food-grade paraffine and medicine-grade Vaseline . It has been successfully used in several industrial units of SINOPEC and PETROCHINA. When the operating pressure is 12Mpa, The light stability of hydrotreated product can reach sy+2, even sy+1.
