Mercaptans are commonly present in petroleum products. Their foul odor and highly corrosive nature make them the most undesirable sulfur compounds so they should be removed because of environmental issues. Merox process is used for oxidation of mercaptans to disulfide using air in the presence of alkaline solution and Merox catalyst. In this paper, due to lack of information about the kinetic o...

The present research introduces adsorption of sulfonated cobalt phthalocyanine catalyst (Europhtal) from the real wastewater that is produced in mercaptan removal unit (Merox) third refinery, South Pars Gas Complex (SPGC), Assaluyeh, Iran. Therefore, novel low-cost natural zeolite modified with polyaluminium chloride (PAC) was investigated as an adsorbent for treatment Europhtal wastewater. Cen...

In the present study, adsorption of Co(tsPc)-4 using γ-Alumina was investigated. γ-Alumina was prepared by gel combustion method. The XRD pattern revealed that the synthesized γ-Alumina is amorphous and SEM image showed its nanosize scale while BET surface area about 501 m2/g and pore size of 7 nm implies highly porous surface which is a characteristic property of a high-quality adsorbent. In t...

In this research, initially, the sol-gel method was employed to produce γ-alumina and TiO2 catalysts with core-shell structure. Iron (III) was used as a dopant. The newlyproduced core-shells were Fe/TiO2// Fe/ γ-Al2O3 (FTFA). Sulfonated cobalt phthalocyanine was used as a dye pollutant in Merox process. By doping Fe in TiO2 catalyst, the ef...

A 78-year-old man was referred for pacemaker implantation due to symptomatic 3rd degree atrioventricular (AV) block. Neither the patient's history nor physical examination revealed abnormalities with regard to his cardiovascular status. Tachyarrhythmias such as intermittent atrial fibrillation or ventricular tachycardia had not been documented in recent years, and the patient was not on medicat...
