Progress is reported on the role of catalysts during relatively low temperature steam gasification. This quarter, catalyst dispersion was studied. A catalyst solvent for impregnation other than water was investigated to observe different wetting effects. A solution of 20% methanol in water was used to impregnate Kentucky {number sign}13 char with K--Ca oxide catalyst. Impregnation of Franklin Pitt {number sign}8 with other alkali and/or earth alkali oxides was also undertaken. Also this quarter, the initial KCa/C ratio was investigated for its effect on methane coupling after essentially complete gasification of the Rosebud char. The importance of the presence of water for the coupling reaction was studied at 640{degree}C. In this case a relatively inactive KCaO{sub x} catalyst derived from impregnation on alumina wool was used, since large enough quantities of catalyst derived from char gasification were not available. Using the relatively low activity KCaO{sub x} catalyst on SiO{sub 2}, the effect of water flow and of temperature was also investigated. 12 figs., 1 tab.
