In this project, we studied alkaline hydrothermal treatment technology as a process to convert cellulosic biomass into hydrogen gas. We used data from Ishida et al to develop kinetic and reactor models to scale-up this technology to farm-scale or industrial production. The kinetic model that was developed was based on our assumption that different microstructures of cellulose undergo degradation at different rates. This model was consistent with much of the experimental data. From our findings, using a plug flow tubular reactor with a NiTiO2 catalyst was the best way to proceed with this process. The best way to obtain this configuration would be to use a circulating fluidized bed reactor.
