TL;DR: In this paper, an efficient and recyclable oxidative desulfurization process (ODS) to remove the most refractory sulfur-compounds (dibenzothiophene, 1-benzothioxhene and 4,6dimethyldibenzithiophene) from fuel is reported.
Journal ArticleDOI
Desulfurization of model diesel by extraction/oxidation using a zinc-substituted polyoxometalate as catalyst under homogeneous and heterogeneous (MIL-101(Cr) encapsulated) conditions
Diana Julião,Ana C. Gomes,Martyn Pillinger,Luís Cunha-Silva,Baltazar de Castro,Isabel S. Gonçalves,Salete S. Balula +6 more
TL;DR: In this paper, a composite material comprising the chromium terephthalate metal-organic framework MIL-101 and the tetrabutylammonium (TBA) salt of a zinc-substituted polyoxotungstate anion, TBA 4.2 H 0.8 [PW 11 Zn(H 2 O)O 39 ] (denoted PW11 Zn), has been prepared by an impregnation method and characterized by powder X-ray diffraction, scanning electron microscopy, N 2 adsorption/desorption
Journal ArticleDOI
Catalytic oxidative/extractive desulfurization of model and untreated diesel using hybrid based zinc-substituted polyoxometalates
Susana O. Ribeiro,Diana Julião,Luís Cunha-Silva,Valentina F. Domingues,Rita Valença,Jorge C. Ribeiro,Baltazar de Castro,Salete S. Balula +7 more
TL;DR: In this article, the desulfurization efficiency of various hybrid zinc-substituted polyoxometalates (PW11Zn(H2O)O39]5−, abbreviated as PW 11Zn) was investigated for the first time and optimized using sustainable systems conciliating successfully the liquid liquid extraction and the oxidative catalytic process.

Carlos M. Granadeiro,André D.S. Barbosa,Patrícia Silva,Filipe A. Almeida Paz,Vipin K. Saini,João Pires,Baltazar de Castro,Salete S. Balula,Luís Cunha-Silva +8 more
TL;DR: In this paper, two hybrid composite materials, PW11 and SiW11@MIL-101, were prepared by the inclusion of the potassium salts of the monovacant polyoxotungstates (PW11) and [SiW11O39]8− (SiW 11), into the porous Metal-Organic Framework MIL-101(Cr).
