The objective of the study was to gasify coal and biomass chars alone and to gasify mixtures of 10:90 and 30:70 biomass to coal ratios. Thermo-gravimetric analysis was carried out for each of the chars and char mixes at temperatures of 900, 1000, and 1100°C using CO2 as an oxidizing agent. Following data collection for individual chars, mixture ratios were employed to observe synergistic effects from biomass char introduced to coal char in gasification experiments. All char samples were obtained from the Department of Energy (National Energy Technology Laboratory) of Morgantown, WV. The char samples included bituminous, sub-bituminous and lignite coal chars along with chars of selected grasses, mixed hardwoods and corn stover. Chars were homogenized prior to experimentation, and sample sizes of approximately 50 mg were used in the study. Gasification rate kinetics were determined for each char sample and first-order modeling was used to quantify the reactions. Statistical analyses were completed using least-square means of Kapp (reaction rate constant) data. Significance was based on P < 0.05 probabilities. Statistical differences were noted among most samples when considering mean Kapp of the chars tested (P < 0.05). Synergistic effects upon coal chars were found when mixing switchgrass char to Illinois # 6 coal char and when mixing corn stover char to Powder River Basin char at 10:90 and 30:70 mix ratios. These effects were not found in combinations of mixed hardwood char with North Dakota lignite char, and it is thought that North Dakota lignite may actually catalyze the reaction of the hardwood material, not vice versa.
