Problem Example 1: combustion of propane Write a balanced equation for the combustion of propane C3H8 in oxygen O2. The products are carbon dioxide CO2 and water H2O. Solution: Begin by writing the unbalanced equation C3H8 + O2→ CO2 + H2O It is usually best to begin by balancing ...
The data from the experiments is used for parameter estimation for the parameters in the model equation. The exercise demonstrates a typical use of modeling and simulation to extract kinetic data from experiments. A lab-scale reactor allows for excellent control of the composition of temperature, ...
In the temperature and composition range of, respectively, 150 ⪕ T ⪕ (Tcritical–20°C) and 2.7 ⪕ NH3/CO2 ⪕ 6.3, it is possible to describe accurately the experimental results by means of an empirical equation based on regression analysis. Experiments suggest that at high ...
