The selective non-catalytic reduction (SNCR) process used to transform nitrogen monoxide molecules into environmentally friendly gases is reviewed with its numerical modeling. The fundamentals of SNCR in terms of chemistry and flow physics are first discussed, to then examine how they impact on the ...
The objective of this study was to calibrate and the Crop Environment Resource Synthesis CERES-Maize (DSSAT v 4.8) model to simulate crop growth, yield, and nitrogen dynamics in a long-term conservation agriculture (CA) based maize system. The model was also used to investigate the relationship...
As an example, O2 reduction by reductant could happen really fast in combustion engine, with majority of energy dissipated as heat. Biological respiration utilizes heme-copper oxidase to reduce O2 in a controllable manor, with more efficient energy conversion than any known oxygen reduction catalysts...
Gas sorption on carbon nanotubes (CNTs) can occur in both the interstitial channel and the inside of the tubes. To evaluate the porous properties of the produced materials, nitrogen gas adsorption and desorption tests were conducted. The results are shown in Fig.4a69. The porosity size distribut...

However, most detailed kinetic models have focussed primarily on fuel lean combustion at ambient pressure. This is far from the conditions in the combustion chamber of an ATR reactor, where the pressure is much above atmospheric and the overall chemistry very fuel rich. Nevertheless, the detailed ...
which have exhibited the ability to represent additional combustion characteristics of real biodiesel; areas where kinetic modeling has shown utility in the study of combustion phenomena, such as the chemistry of soot and nitrogen oxide formation; and finally comments on limitations and needs for future...
