Abstract
Catalysts are disclosed for the hydrotreatment of hydrocarbons, and particularly for reforming, which contain no platinum and which consist of: PA1 A refractory-mineral carrier (alumina). PA1 0.05 to 5 wt. % of at least one first metal from the group consisting of iron, cobalt, and nickel. PA1 At least one second metal from the group consisting of tin (0.01 to 5%), lead (0.01 to 10%), and germanium (0.01 to 4%). PA1 Possibly from 0.01 to 0.5% of sulfur. Processes for preparation of these catalysts, by impregnation, and for their use are disclosed. It is preferable to deposit the metal (or the metals) from the tin-germanium-lead group before the metal or metals from the iron-cobalt-nickel group are deposited.
