- W147976800 abstract "This summarizes the activities of Sandia National Laboratories' program on mineral matter effects in coal gasification. The objective of this program is to deverop a fundamental understanding of the mechanism of the catalytic effects of mineral matter on coal gasification, and to use this knowledge for future process improvements. We have performed experiments to ascertain the mechanism of the catalytic activity observed for various iron compounds and to optimize this catalytic activity. We determined that addition of Fe/sub 2/O/sub 3/ to Bruceton coal lowers the activation energy for char gasification in H/sub 2/ from 40 kcal/mole to 25 kcal/mole, suggesting a change in mechanism for the catalyzed system. We have also observed that for 5..mu.. Fe/sub 2/O/sub 3/, a plateau in gasification rate (approx. 20 times the non-catalytic rate) is reached at approx. 5% by weight loading. Studies on improved catalyst dispersion techniques have shown that vacuum impregnation of coal by FeSo/sub 4/ results in a gasification rate 4 times greater than if FeSO/sub 4/ is dry mixed with the coal, but is still about one-half the gasification rate for dry mixed Fe/sub 2/O/sub 3/." @default.
