The nature of aggregation kinetics of colloidal asphaltene particles in mixture of toluene and heptane was investigated by utilizing a polarizing microscope with appropriate magnification. The concent...
Adsorption of sulfur oxide is one of the key techniques for producing extra-low-sulfur content naphtha during oxidative desulfurization. Reactivation and repeated use of adsorbent are quite important...
Combustion catalysts free from precious metals, such as platinum, for removal of volatile organic compounds were investigated. Common metal oxides (titanium(IV) oxide (TiO2), alumina and silica) were...
Friedel-Crafts acylation of toluene with benzoic anhydride to produce phenyl tolyl ketone was studied over various ion exchanged heteropoly acids (HPA). Metal chloride such as AlCl3 was not used as a...
