Biological conversion of biomass to methane, the effect of reactor design on kinetics
An experimental program was conducted to evaluate the effect of reactor type on methane production. This study showed that if a balanced population of organisms can be maintained in the initial stage, multi-stage fermentation is more efficient than a complex mix system. However, when the system is stressed, failure in the multi-stage system is more rapid. If the objective is to maximize the conversion of solids to methane, a staged system will produce more methane per unit volume of reactor. If the objective is to maximize the methane production per unit volume of reactor, a single stage complete-mix reactor operating near the critical retention time is required.
