A type of novel mineral-derived catalyst (MDC) composed vanadium–titanium magnetite and sintering ore was prepared via calcination or acid modification for selective catalytic reduction nitrogen oxides (NOx) with ammonia (NH3) to reduce the production cost simplify preparation process. Characterizations by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectromet...

Abstract In recent years, due to the installation of selective catalytic reduction (Selective Catalytic Reduction, hereinafter referred as SCR) devices, high temperature oxidation failure has occurred frequently in automobile exhaust systems. To explore its mechanism, this paper takes 439 ferritic stainless steel which is often used pipes an example and uses XRD, SEM, EDS experimental methods s...

Following the Kyoto protocol with respect to reducing emissions of greenhouse gases emissions, and EU energy policy and sustainability in waste management, there has been an increased interest in the reduction of emissions from waste disposal operations. From the point of view of nitrous oxide (N2O) emissions, waste incineration and waste co-combustion are very acceptable methods for waste disp...

The nitric oxide (NO) removal capacity of ion-exchanged zeolite Y obtained from coal combustion fly ash was evaluated in this work. Zeolite Y was exchanged either with Cu or Fe to obtain two different catalysts for the selective catalytic reduction of NOx from flue gas. The selective catalytic reduction experiments were carried out at temperatures ranging from 50°C to 350°C, water content 0% an...
