The objective of this thesis is to analyze the ethanol autothermal reforming (ATR) process, and to determine which factors and how affect the obtained gas composition, the heat amount, required for the process, the reforming process efficiency, and to find the optimum factor values providing the maximum hydrogen concentration as the result. To reach this objective the following tasks have to be solved: • To develop a bioethanol ATR process thermodynamical analysis model, which helps to define interconnections between process factors as well as the influence of these on the reformed gas composition and on the amount of heat necessary for the process. To estimate the values of process factors, which ensure that no carbon is formed during the process as well as minimum carbon monoxide and methane concentrations and maximum hydrogen concentration are obtained. • Using a theoretical research model, to make optimization in order to define the optimum values of factors, which are required for achieving the maximum hydrogen concentration and the maximum efficiency. • Based on the theoretically defined ranges of the optimum values of factors to perform the experimental research of bioethanol ATR process. • To make regression analysis of the experimental data and to obtain regression equations which allow determining hydrogen, carbon monoxide and methane concentrations depending on the essential bioethanol ATR process factors. • By means of the regression equations to determine the optimum values of bioethanol ATR process factors at which the maximum concentration of hydrogen can be reached.
