Project Details
Description
Professor Dr. Harold H Kung at Northwestern University will assist Dr. Maohong Fan at University of Wyoming in preforming the following tasks.
Task 3 is to evaluate the effect of various factors on the catalytic PRB coal gasification with dry CO2 for more CO production
The task is to study the catalytic dry CO2 gasification results under various conditions. Carbon conversion will be defined on a dry, volatile-free, ash-free and catalyst-free basis. The rate of carbon conversion represents the gasification rate per unit weight of residual char. The factors to be investigated include coal particle size, temperature, the loading of catalyst on coal, and the Fe:Na ratio. Coal particle size can significantly affect the performance of catalyst on coal gasification with CO2. The sizes of coal to be used in the proposed project will be in the range of 0.025-0.25 mm. Temperature directly affects the kinetics of the reaction between CO2 and C in the char resulting from coal pyrolysis. The tested temperature range will be 700-900oC. The differences in those changes between as-received and catalyzed coal gasification with CO2 with a given temperature range will be compared. The total loading of the Fe-Na catalyst will be in the range of 1-5% by weight, while the Fe:Na ratio varies.
Task 4 is to evaluate the effect of various factors on the catalytic PRB coal gasification with CO2-H2O for more H2 and CO productions
WGS reaction will occur within gasifier when H2O is introduced. All the factors mentioned in Task 3 will be evaluated to see how they affect the H2 and CO production when wet CO2 is used. Different CTL processes require different ratios of H2 and CO. Thus the evaluation will be conducted on how to control gasification conditions to produce syngas with desired H2:CO ratios.
