Technical Abstract: Blended swine solids, chicken litter, and rye grass were pyrolyzed using a skid-mounted sytem. Produced gas composition was analyzed for major hydrocarbons and S-containing compounds. Charcoal was analyzed for its surface functional groups, contact angles, HHV, and total element contents. Some of the charcoals were also activated using both physical and chemical methods. The energy content of the produced gas from swine solids was slightly lower than that of natural gas. The calorific values of charcoals from blended swine solids were comparable to that of fossil coals. Adsorption characteristics of activated and non-activated charcoals are currently under evaluation.
