Abstract

LINARES, Carlos F et al. Study of venezuelan garnierites modified with ammonium hydroxide as support of hydrodesulfurization catalysts. Rev. LatinAm. Metal. Mater. [online]. 2015, vol.35, n.1, pp.65-69. ISSN 0255-6952.

Garnierite, it is a compound forming for talc and serpentine mineral phases, it is rich in Ni. This compound was treated with different ammonium hydroxide concentrations: 0, 2 and 4M for increasing the specific area of these solids. Then, the base treated mineral was impregnated with a Mo solution (15% w/w as MoO₃). These solids were characterized by physicchemical technique different such as: X-ray diffraction, FT-IR, BET specific area and chemical analysis. Mo impregnated solids were tested in the thiophene hydrodesulfurization reaction; Results showed a relationship between the HDS reaction and the specific area of these solids.

Keywords : garnierite; Ammonium Hydroxide; Thiophene; HDS; Specific Surface Area.
