According to the cyclic voltammetry(CV) curve of LaxSr1-xNiO3( x=0.15, 0.70, 0.75,1.00)function al oxygen electrode at various temperature, the chemical dynamic parameter ln Ic and 1/T, or -ln Va and 1/T, are both linear, while the activation energy of oxygen reduction and evolution are obtained.
Through the adoption of a plug flow reactor in Chemkin 4.0 software package and chemical dynamic models established by Miller (1989) and others, a simulation calculation and contrast analysis have been conducted of the principle of reburning, advanced reburning, SNCR (selective non-catalytic reduction) and hydrocarbon-added SNCR reactions. In this connection, the effect of different reaction temperatures, reburning fuel ratios and residence time on denitration efficiency has also been studied.
A little dose of samples and reagents is enough for analyses in this experiment. The method is proved to be simple and operable, and can help observe the chemical dynamic behavior of nitrogen and phosphorus of release-controlled fertilizer in seawater.
In this paper, a quantitative chemical dynamic model is presented which calculates the ratio of organic matters generating oil and gas with Binbei region's thermal history on each stage , area, layer source rocks. The results indicate that the maturation of most source rocks are lower and even though in the central sunken area , gen- erating oil is dominant.
Chemical kinetics calculation and experimental research were used to find out the mechanism between N2O and N-agent species, N-agent/NO nitrogen stoichiometric ratio (NSR), reaction temperature, reaction time, etc.
The seven kinetic parameters of the calibrated model are determined using a combination of the Micro-Genetic Algorithm and the SENKIN program of CHEMKIN chemical kinetics software package.
It was demonstrated that simulation of thermal aging of canned fish on the basis of on the laws of chemical kinetics may be used for predicting quality changes and determining shelf life.
On Advantages of Simple Approaches in Chemical Kinetics: A Combination of Temperature and Isothermal Variations in the Viscosity
Moreover, to date the chemical kinetics have received little study, and there are simply no reliable data that can be used in the calculations.
With ever-increasing attentions being paid to complex systems such as the life system, soft matter, and nano-systems, theoretical studies of non-equilibrium nonlinear problems involved in chemical dynamics are now of general interest.
In this mini-review, we mainly give a brief introduction to some frontier topics in this field, namely, nonlinear state-state dynamics, nonlinear chemical dynamics on complex networks, and nonlinear dynamics in mesoscopic chemical reaction systems.
Infrared fluorescence, a versatile probe in chemical dynamics
The study of reactive and inelastic energy transfer collision events forms a cornerstone of modern chemical dynamics and kinetics.
Results from our laboratory are presented in which state-of-the-art IRF is used to study a broad spectrum of problems in chemical dynamics.
Mathematically, such a problem leads to the simultaneous numerical solution of the gas-dynamics equations for the flow parameters and the chemical kinetic equations for the concentration of the individual components.
We note the use of a local linearization of the chemical kinetic equation system, as employed in .
