In the current study, reduction of nitrogen oxide from exhaust gas in the presence of NH3 as reductant on selective catalytic reductant (SCR) impregnated catalytic converter was simulated using Comsol© software. Mass transfer (one-dimensional) and heat transfer (three-dimensional) governing equations were taken into account to model the unsteady state behavior of the catalytic converter. Modeli...

The air pollutions from combustion flue gas and industrial gases became worse and cause the environmental problem. It is difficult for the conventional methods such as selective catalytic reduction method and lime-gypsum method to treat exhaust gases energy efficiently and inexpensively. Its energy efficiency and its initial and running costs are still in negative situation for the backward nat...

Effects of water on the catalytic performances of MoVTeNbO catalyst in the oxidation of propane to acrylic acid have been investigated at different reaction temperatures and different steam contents. Obtained results show that both catalytic performances and catalyst structure are very sensitive to the presence of water vapor in the reaction feed. Presence of water induces some structural modif...

Selective hydrogenation of halonitrobenzenes into haloanilines represents a green process to replace the environmentally unfriendly non-catalytic chemical reduction in industry. However, this transformation often suffers from serious dehalogenation due easy break carbon-halogen bonds on metal surfaces. Modulations electronic structure supported Pd nanoparticles Lewis-basic layered double hydrox...

Thermal power plants in different fields are regularly adapted to the state-of-the-art emissions standards, applying “The Best Available Techniques Reference”. Since 2016 plant area new, more stringent limits for units with a thermal output of than 300 MW operated black coal valid. Usually, order reach new e.g., NOX emissions, downstream reduction processes (Selective Non-Catalytic Reduction, S...

Catalytic thermolysis is considered to be an effective process for viscosity reduction, the conversion of high-molecular components oil (resins and asphaltenes) into light hydrocarbons, desulfurization hydrocarbons. In this paper, we conducted non-catalytic catalytic a heavy sample isolated from Ashalcha field (Tatarstan, Russia) at temperature 250 °C. Fullerene C60 nanoparticles were applied p...
