Mathematical Model for the Simulation of the Syngas Methanation Process

Biomass is a unique renewable resource with a wide range of uses and a huge potential. However its relevance for food industry poses an ethical dilemma. Therefore, finding the possible solutions for more efficient biomass use are increasingly important. In this paper, results of a study identifying parameters and conditions necessary for increasing the quality of outgoing gases from biomass gasification and digestion processes are presented. A methanation process is simulated for upgrading the quality of the gases. It is a reaction where carbon oxides present in the gases react with hydrogen to produce methane. The reaction is condition-dependent, therefore a mathematical model is developed for simulating parametric values that influence the process. In the paper, the simulation results are presented.
