Garnierite: A new support for hydrodesulfurization catalysts

Abstract:

A Venezuelan garnierite sample from "Loma de Níquel" mine was treated with acid solutions of different concentrations. This method allowed an increase of BET surface area and a partial removal of Ni according to the acid concentration. The resulting solids were impregnated with Mo and their activity was tested in the thiophene hydrodesulfuration reaction. It was found that an increase of the surface area is positive for using garnierite sample in HDS reaction as long as the Ni removal was not excessive. © 2014 Elsevier B.V.
