The fixed-bed reactor experimentation was completed. The effectiveness of calcium fluoride, sodium dihydrogen phosphate, and calcium phosphate in extending alkali catalyst lifetime or recyclabilities was determined. In addition the effect of solution impregnation on catalyst performance for the char-lime-steam reaction was also determined. Most of the components for the elevated pressure fluid-bed reactor were received and the assembly of the laboratory reactor started. Finally, several experiments have been conducted to observe the behavior of the acceptor material and to resolve certain difficulties concerning the performance of these materials. In catalyst-acceptor physical-chemical properties task the following was accomplished: determining of the char-sulfur retention properties of acceptor-catalyst systems, completing optical, scanning electron microscope, and x-ray diffraction analysis of deactivated catalyst systems in reaction ash residues, and measuring the relative carbon dioxide absorption properties of chemically pure lime and a recalcined natural dolomite. Principal accomplishments made under the catalyzed steam-oxygen-char reaction studies task include completing experiments to measure the effect that catalyst concentration had on the rate and product composition of the char-steam reaction, and determining the recyclability performance of five catalyst systems for the char-steam reaction, using the fixed-bed reactor. Under the engineering studies task, a block diagram of the conceptualized catalytic gasification process was prepared and a process design basis developed. A preliminary process flow diagram was completed and material and energy balances around lack of the process unit operations made. Identification and sizing of the major pieces of process equipment was initiated.
