A comparison of the resistance to deactivation of Ni-Mo hydroprocessing catalysts supported on alumina, carbon and carbon-covered alumina in gas oil and model compound reactions
Oxidative desulphurization of gas oil and model compounds that exist in gas
oil with hydrogen peroxide/acetic acid using nanoparticle
(Bu4N)7H3[P2W18Cd4(Br)2O68]-TiO2 ((Bu4N)7H3[P2W18Cd4]-TiO2) as a nano
scavenger has been studied. This sandwich-type nanoparticle was shown be
able to scavenge hydrogen sulfide and mercaptans with high yield. The
addition of acetic acid enhanced the conversion. This system provides an
efficient, convenient and practical method for scavenging of sulphur
compound. The (Bu4N)7H3[P2W18Cd4]-TiO2 nanoparticle was very active catalyst
system for the model compound oxidation, while other polyoxometalate systems
were much less active.
