A transient, two‐culture model simulating methane production from biomass has been developed. The simulator, based partially on the work by Andrews and McCarty, is capable of calculating the hydrolysis products of several common organic materials, accommodating various substrate feeding modes, and simulating the transient physico‐biochemical transport and conversion processes occurring in the biological, liquid, and gaseous phases of a well‐mixed reactor. The mathematical representation of this bioconversion system consists of a set of 11 coupled, nonlinear first‐order rate equations based on the principles of mass conservation and biochemical reaction kinetics. The model can be used in conjunction with laboratory investigations and as a simulator for evaluating process control strategies and cost developments.
