摘要： The present invention deals with activation and start-up procedures of catalysts for the deep HDS of middle distillates for producing ultra low sulfur diesel (ULSD), consisting of two in situ activation stages: at stage 1, TGA is applied, and at stage 2, DMDS is used; kerosene is the transport means at these stages, which are carried out under given temperature and pressure conditions, and feedstock and hydrogen flows at established times. After the activation of the catalyst in situ, the stabilization stage takes place under selected temperature and pressure conditions, feedstock and hydrogen flow at established times, with which the stabilization of the highly dispersed metallic sulfides is achieved and, in this way, the activity of the catalysts removing contaminants for the production of ULSD is increased.
