The objective of the project was to determine the best reactor configuration and optimum operating conditions for anaerobic digestion of each of four prototype feeds - water hyacinth solids/sludge, kelp, sorghum, and poplar - representing feedstocks of varying lignin content. A kinetic analysis of two different reactor types recovering a blend of water hyacinth and sludge indicated better performance of a non-mixed upflow solids reactor (USR) to that of a continuously stirred tank reactor (CSTR). The results of preliminary lab analyses and systems calculations suggest that substantial improvement in performance is possible by digestion of low-solids juice in an ambient temperature reactor and hyacinth solids in a different reactor. A kinetic analysis of kelp digestion also indicated superior performance of the USR over the CSTR digester. Conversion yields and rates and process stability were shown to be greater in a kelp lot with higher mannitol content. Preliminary results suggest that a two-phase leachate-bed recycle system may be most effective for biogasification of wood.
