Description
Summary:The purpose of this study was to investigate the influence of water content on the concentration of Orimulsion pyrolysis products, calorific value of product gas, cold gas efficiency, and coke formation coefficient. To achieve this objective, a numerical algorithm, based on thermochemical equilibrium, was developed to simulate the pyrolysis process. To improve the model accuracy, the model was first modified by a common method available in the literature. The modified model in the term of products yield was compared with the experiments literature and observed a reasonable agreement between the numerical results and experimental data. The produced gas HHV in pyrolysis process was found to be sensitive to water content, while cold gas efficiency and the coke formation coefficient were less sensitive. Finally, based on the simulated results, an optimal condition is suggested to improve produced gas HHV in Orimulsion pyrolysis process.
