Hydrotreating of heavy gas oil using CoMo/γ-Al2O3 catalyst prepared by equilibrium deposition filtration

A novel catalyst of Ni,W-surface-Ti-rich-ETS-10/Al 2 O 3 : Its role and potential of HDS performance for steric hindered sulfur compound 4,6-DMDBT

“…The type II active phase is highly stacked and weakly interacted with support, exhibiting higher activity than type I active phase [4]. Novel supporting materials development is a promising approach for highly active HDS catalyst s with highly dispersed Co(Ni)Mo (W)S type II phase [5][6][7][8]. Various support materials such as carbon nanotube [9], silica [10], V 2 O 5 /Al 2 O 3 [11] and SiO 2 /Al 2 O 3 [12] have been studied for HDS catalysts.…”

Adsorption of T.N.T. from Wastewater Using Ni-Oxide and Cu-Oxide Nanoparticles

“…The vast majority of the total surface area and pore diameter of all samples were emanated from mesopores. Such mesoporous structure would be propitious for adsorption purposes in terms of improved accessibility of the adsorbent to the active binding centers within the porous structure of samples, ubiquitous existence in effluents worldwide, extreme toxicity and hazardous nature towards many living creatures, high water solubility, and increased persistence in aquatic ecosystems 44,45 .

Hydrotreating Activity of Co-Mo/Al2O3 Promoted with Boron and Phosphorous

“…In this way, impregnated with a solution containing the required amount of phosphoric acid (H3PO4) in the water on a commercial CoMo/Al 2 O 3 catalyst, and the pH of the solution was 3.5. This was followed by saturation of support by drying for 12 hr at 120 o C and calcined at 500 o C for 4 hr [18].…”
