The kinetic of Fischer-Tropsch synthesis over a co-precipitated Fe-Ce catalyst was investigated in a fixed bed micro reactor. Experimental conditions were varied as follow: reaction pressure 1-15bar, H¬¬¬2/CO feed ratio of 1-3 and space velocity of 3600-5400 h-1 at the temperature range of 270-310°C. 4 models according to the Langmuir-Hinshelwood-Hougen-Watson (LHHW) type rate equation were der...
Abstract T his paper is to convince the usage of the nonlinear unit root tests when dealing with a nonlinear model. To do so, the stationary test for variables in a model titles “Fiscal Reaction Function in Iran” has been applied according to both the ordinary and the Nonlinear Dickey-Fuller (NDF) tests. Results show that while variables under investigation are stationary ...
One of the characteristics of solid organic compounds and especially organic explosives is thermal behavior and kinetic of thermal decomposition. The activation energy, Arrhenius constant and model of solid state reaction as kinetic triplet can be obtained by study thermal decomposition kinetic in a solid state reaction. In the present work, the non-isothermal differential thermal analysis (DTA...
The effect of ball milling on kinetics of the thermite reaction of 3Fe2O3 + 8Al powder mixture to synthesizeFe3Al-Al2O3 nanocomposite was investigated using differential thermal analysis. A model-free methodwas applied to the non-isothermal differential calorimetry (DSC) data to evaluate the reaction kineticsaccording to the Starink method. The activation energy of the thermit...
