This work reports supercritical water oxidation (SCWO) of organic pollutants in industrial wastewater the absence and presence catalysts. To increase efficiency process, SCWO compounds was performed various iron- manganese-containing heterogeneous catalysts (Fe-Ac, Fe-OH, Mn-Al). The catalytic non-catalytic from PJSC “Nizhnekamskneftekhim”, generated epoxidation propylene with ethylbenzene hydr...

background: catalytic ozonation has recently been applied as a new method of contaminant removal from water and wastewater. in this study, copper coated pumice and zeolite were used to catalyze the ozonation of phenol as a target pollutant from aqueous solutions. methods: the pumice and zeolite stone were modified by cuso 4 (1n). modified pumice and zeolite were characterized by adsorption/deso...

A novel approach is developed for desulphurization of fuels or organics without use of catalyst. In this process, organic and aqueous phases are mixed in a predefined manner under ambient conditions and passed through a cavitating device. Vapor cavities formed in the cavitating device are then collapsed which generate (in-situ) oxidizing species which react with the sulphur moiety resulting in ...

Chemical reactions reflect the universal tendency of systems to approach equilibrium. The dynamics towards equilibrium, reflected in rates of chemical reactions, are therefore influenced only by thermodynamic properties, such as reaction affinity and the chemical potential, activity, or fugacity of reactants and products. Reaction rates depend on concentrations only in ideal reaction mixtures, ...

Hydrogen peroxide (H2O2) is a strong oxidizing agent. High concentration H2O2 or High Test Peroxide (HTP) has been used extensively in the past in propulsion applications as mono and bipropellant. At low temperature, HTP can be catalytically decomposed to water and oxygen. Drawbacks to this approach include catalyst poisoning due to the presence of stabilizers in HTP, and susceptibility of the ...
