SYNERGIC PROMOTION OF CATALYST BY GROUP VIII B ELEMENTS [PDF]

Journal of Sciences, Islamic Republic of Iran, 2002
Group VIII B metal oxides supported on gamma-alumina were investigated as catalysts and promoters of MoO3 hydrodesulfurization catalysis. Superior promotion was observed in PbO promoted catalyst compared to that of CoO, the typically accepted promoter ...

Olefin separation from FCC naphtha by deep eutectic solvents: PC‐SAFT modeling and molecular insights

AIChE Journal, Volume 72, Issue 2, February 2026.
Abstract Olefin extractive separation from fluid catalytic cracking (FCC) naphtha with deep eutectic solvents (DESs) was systematically investigated in this work. In a first step, different DESs were screened for their separation performance of the binary mixture benzene/1‐hexene.

Influence of Preparation and Activation on the Speciation of Carbon‐Supported Mo–W Carbides

ChemCatChem, Volume 18, Issue 4, 25 February 2026.
In situ X‐ray absorption spectroscopy (along with XRD and TEM) combined with MCR‐ALS resolves the speciation of carbon‐supported Mo/W carbides during carburization. This analytical approach links preparation pathways to active phase formation, providing insights for the rational design of carbide catalysts.

The Effect of Coking on Kinetics of HDS Reaction under Steady and Transient States [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2004
A study was made of the coking of a commercial fresh sulfide Ni-Mo/Al2O3 catalyst in a fixed-bed reactor. The catalyst was coked using different coke precursors in the gas oil under accelerated conditions at temperatures of 400 to 450°C to yield ...

Size Effects of TiO2 Nanoparticles as Supports for W‐ and NiW‐Catalysts for Selective 3‐Methylthiophene Desulfurization

ChemCatChem, Volume 18, Issue 1, 15 January 2026.
Rounded TiO2 nanoparticles we sucesfully synthesized with modulated sizes from 109 to 22 nm. We observed the WS2 and NiWS active phases forming parallel slabs to the surface. The presence of Ni helped W to be better dispersed, especially on the smallest nanoparticles, which resulted in the highest activity detected among the series.

Modulation of the Acidity of HY, HBETA, and HZSM‐5 Zeolites by Lanthanum Incorporation for Selective Gasoline Desulfurization in the FCC Riser

ChemCatChem, Volume 17, Issue 21, November 10, 2025.
Desulfurization in the FCC riser is achieved by modifying zeolite catalysts with La3+ ions, promoting H2S formation from thiophenic compounds while suppressing secondary reactions. This approach enhances gasoline quality by increasing selectivity for H2S and enabling efficient condensation and alkylation, supporting cleaner fuel production and ...

Hydrodesulfurization of Thiophene over Ni‐Doped MoS2‐Supported Mesoporous Silica

ChemCatChem, Volume 17, Issue 22, November 24, 2025.
The catalytic conversion of thiophene to paraffinic hydrocarbons is presented using mesoporous SBA‐15‐supported MoS2 and NiMoS2 catalysts. Few‐layer MoS2 nanosheets decorate the surface and pore walls, while Ni incorporation enhances hydrogen activation and promotes NiMoS phases.
