“…Monolithic catalysts have become the most diffuse and economically significant application of catalytic reaction engineering and industrial catalysis so far [161]. This is due to the commercial success of such well-known environmental catalysis processes as: (i) the purification of exhaust gases from automobiles [162,163], (ii) the abatement of NO x emitted in the stack gases from power stations by selective catalytic reduction processes [162,164], (iii) the catalytic combustion of VOCs [165,166] and space propulsion [167]. Their potential for application in heterogeneous catalysis has also been widely investigated, as reviewed by Cybulski and Moulijn [168].…”

Volatile organic compounds (VOCs) are harmful to environment and human health. Catalytic oxidation has been used in VOC abatement for over 60 years, and it has proven to be an effective technology. A large variety of VOCs set high demands for the treatment, and therefore catalytic oxidation needs still to be developed further. This paper reviews current aspects and future research needs related to VOCs and catalytic VOC treatment concentrating on solvent-based, chlorinated and sulphur-containing VOCs.

“…As research shows, vanadium based catalysts is recognized as a high transforming activity catalyst, and, of which, the ability of preventing from SO 2 poisoning is significant. The highest temperature that vanadium based catalysts could bear is the range of 550-600℃ [7,8,9]. The catalyst is usually cellular honeycomb structures, which enabled more ordinary NH 3 molecules attach to the surface of the catalyst, thus, convert to active NH 3 molecules.…”

Abstract. With the global environment worsening and the consciousness of protecting environment strengthening, the limitation of noxious gas from diesel engines is becoming more and more strictly. Selective catalytic reduction (SCR) aftertreatment system has been applied to reduce Nitrogen Oxides (NOx) as a key technology. The urea solution injected into the tailpipe decomposes to ammonia, which will react with NOx on the surface of SCR catalyst. The main purpose of this paper is to study the effect of different concentrations of NO, NO2 and NH3 on the reactions taking place with SCR catalyst by simulation. Based on mass transfer equations and chemical kinetics the simulation results predict the concentrations of NO, NO2 and NH3 accurately. The mass conservation equations of species are solved by the software MATLAB. Some regulations can be revealed to improve the NOx conversion efficiency and reduced the NH3 slip.
