This report describes work performed on a program directed towards investigating the effects of peat hydrogasification in an entrained flow reactor. The program was conducted in three phases: peat dense-phase feed system flow studies, hydrogasification entrained flow reactor testing, and preliminary peat process economic evaluations. The peat dense-phase feeding studies included low-pressure (below 150 psig) testing at nominal solid peat flow rates of 1 ton/hr and analytical modeling efforts. The hydrogasification reactor testing was performed at peat flow rates of over 1000 lb/hr and reactor temperatures to 1900/sup 0/F in hydrogen atmospheres from 500 to 1000 psig. A simple analytical kinetic model was developed to predict total carbon conversion as a function of reactor operating variables and its agreement with experimental data was found to be excellent. Finally, preliminary process economics were established for three variations of the Cities Service/Rockwell (CS/R) Flash Hydropyrolysis Process with the cost of high-Btu gas ranging from $3.43 to $4.06 per million Btu.
