To expand the utilization of coat it is necessary to reduce the technical and economic risks inherent in utilizing a feedstock which is highly variable and which sometimes exhibits unexpected and unwanted behavior. Reducing the risks can be achieved by establishing the technology to predict a coal's behavior in a process. This program is creating this predictive capability by merging technology developed at Advanced Fuel Research, Inc. (AFR) in predicting coal conversion behavior, and technology developed at Brigham Young University (BYU) in comprehensive computer codes for modeling of entrained-bed gasification. Additional capabilities in predicting pollutant formation will be implemented and the technology will be expanded to fixed-bed reactors. The foundation to describe coal-specific conversion behavior is AFR's Functional Group (FG) and Depolymerization, Vaporization, and Crosslinking (DVC) models. The FG-DVC model is being improved and integrated with BYU's comprehensive two-dimensional reactor model, PCGC-2 and with a new one-dimensional advanced fixed-bed code. The program consists of four tasks: (1) Preparation of Research Plans, (2) Submodel Development and Evaluation, (3) Comprehensive Model Development and Evaluation, and (4) Applications and Implementation. This paper covers work during the past year in Tasks 2, 3, and 4.
