Reducing environmental pollution via elimination of sulfur compounds from gas condensate was the aim of this research. Whereby oxidative desulfurization from gas condensate with 3200 ppm initial sulfur was accomplished by hydrogen peroxide (30%wt) as oxidant and formic acid as catalyst. The sulfones after generation in the oxidation step were extracted through a method of liquid-liquid extracti...

Sulfur is one of the most significant impurities in coal, which reduces the quality of coal and also results in environmental pollution. This work was aimed to investigate the removal of sulfur from coal by the leaching method employing parameters expected to affect the removal rate such as acid concentration (10-30%), temperature (40-80 °C), and reaction time (40-100 min). A response surface m...

In this paper, the effect of sodium humate (HA-Na) and seawater on absorption SO2 in flue gas was investigated. At same time, effects initial pH value concentration desulfurization were also evaluated. The experimental results showed that had ability to absorb SO2. dissolved can react with HCO3– CO32– plasma produce CO2, which prompt reaction. Besides, addition HA-Na improve performance increas...

In some applications, deep desulfurization and deoxidation of steels without the use aluminum are required, using Si as a deoxidant instead, with double-saturated slags in CaO-SiO2-CaF2-MgO system. This work studied nonmetallic inclusion evolution for system an induction furnace compared results FactSage kinetic simulations. Steel samples were taken from steel melt analyzed ICP-MS combustion an...

In the present study, removal of dibenzothiophene (DBT) from model oil (n-hexane) was investigated using magnetic activated carbon (MAC) nano-composite adsorbent. The synthesized nano-composite was characterized by FT-IR, FE-SEM, BET and VSM techniques. The MAC nano-composite exhibited a nearly superparamagnetic property with a saturation magnetization (Ms) of 29.2 emu g-1...

The modelling of the in-duct desulfurization process at low temperatures was performed from data obtained in an entrained flow reactor at laboratory scale. Two modelling approaches were used for the process description under in-duct conditions in the reactor: (i) the application of the grain model to a single particle along the reactor, and (ii) a non-ideal adsorption equation for the gas–solid...

A series of Zn-modified NaY zeolites were prepared by the liquid-phase ion-exchange method with different Zn sources, including Zn(NO₃)₂, Zn(Ac)₂ and ZnSO₄. The samples were tested as adsorbents for removing an organic sulfur compound from a model gasoline fuel containing 1000 ppmw sulfur. Zn(Ac)₂-Y exhibited the best performance for the desulfurization of gasoline at ambient conditions. Combin...
