Mixed NiMo, NiW and NiMoW sulfides obtained from layered double hydroxides as catalysts in simultaneous HDA and HDS reactions

Arias S, Licea YE, Soares D, Eon JG, Palacio LA, Faro AC

NiMoAl, NiWAl and NiMoWAl hydrotreating catalysts were prepared from NiAl- terephthalate layered double hydroxides (LDHs), by ion exchange of the therephthalate anion by heptamolybdate (Mo7O246-) and/or metatungstate (H2W12O406-). The Mo- and/or W-containing LDHs were sulfided, either by direct sulfidation (DS route) or after previous calcination (PC route).
