This quarterly report, for the period April through June 1981, summarizes the activities of Sandia National Laboratories' program on mineral matter effects in coal gasification. The objective of this program is to develop a fundamental understanding of the mechanism of the catalytic effects of mineral matter in coal gasification, and to use this knowledge for future process improvements. Experiments using various catalyst dispersion techniques indicate that for a given iron compound, improved dispersion results in improved catalytic activity. We observed that the addition of inert or catalytically active minerals eliminated agglomeration in the Bruceton coal. We also determined that addition of the iron catalyst increases the surface area and shifts and pore sizes, but the magnitude of the effect varies greatly from one compound to another. Results presented indicate that the mechanism for catalytic enhancement of hydrogasification is similar for the various iron compounds and that differences in activity can be correlated with the number of active Fe sites. We have begun a series of experiments to study the degree of H/sub 2//D/sub 2/ exchange over various reduced iron catalyst to assess their relative activity towards hydrogen transfer.
