| dc.description.abstractEn | Unsupported and high specific surface area (SBET) catalyst precursors for deep-hydrodesulfurization (deep-HDS) are obtained using an environmental friendly, continuous and fast synthesis process in supercritical water/alcohol mixtures. This approach offers an access to high production rate and upscaling. Two mixed oxides were synthesized: NiMoO4, which is the preferred material when deep-HDS is investigated, and CoMoO4 preferred for simple HDS. The role of the water/alcohol mixture on the resulting specific surface area has been studied and allows a controlled adjustment of the resulting specific surface area. The obtained NiMoO4 material consists of the highly active hydrate NiMoO4.0.75H2O phase with a controlled composition and specific surface area up to 200 m2 g−1. Resulting materials have shown great performances when tested in deep-HDS catalytic tests. | |
