Abstract—The major harmful automobile exhausts are nitric oxide (NO) and unburned hydrocarbon (HC). Reduction of NO using unburned fuel HC as a reductant is the technique used in hydrocarbon-selective catalytic reduction (HC-SCR). In this work, we study the microkinetic modelling of NO reduction using propene as a reductant on Pt catalysts. The selectivity of NO reduction to N2O is detected in ...

The effect of illumination on the surface interaction and the reaction between NO ? C2H5OH was investigated on TiO2 and Ag/TiO2. By means of Fourier transform infrared spectroscopy the formation of an absorption band at 2,210 cm was observed on pure TiO2, which was attributed to the NCO species. Similar measurements on Ag/TiO2 produced another spectral feature at 2,170 cm, which was assigned to...

In recent years, studies on denitration by applying biomass reburning method has drawn the attention of many researchers due to the characteristics of low sulfur and nitrogen content, high volatile, high ash focal activity, zero CO2 net emissions, etc. Based on Chemkin software and selective non-catalytic reduction (SNCR) denitration chemical kinetic model, this paper conducted SNCR denitration...

The NO heterogeneous reduction by char is one of the most prominent options to control NOx emissions from coal-fired power plants. Experiments on char-NO reaction were carried out in an electrically heated fixed-bed reac-tor investigate effect temperature, type char, pretreatment method, additives and atmosphere capacity char. re-sults showed that temperature plays a crucial role differ-ent kin...
