Abstract: We developed a H2 and C1-C4 heterogeneous mechanism to describe their catalytic reaction on a platinum catalyst. To verify the mechanism we carried out simulations with methane, ethane, propane, and n-butane and compared the results to the reported experimental data. The ignition and combustion (ignition or combustion of CH4, C2H6 with or without adding H2, C3H8 with or without adding H2, C4H10 with adding H2) was of interest. Good agreement was obtained and we found that H2 improved the ignition of propane and n-butane, and the combustion of ethane. However, their kinetic processes are different. Therefore, the H2 and C1-C4 heterogeneous mechanism determined in this work is reasonable with some certainty and could be used to describe the characteristics of ignition and combustion, which can be used to analyze the kinetic process.
