The latest conclusions by Union Oil Co. concerning oil-shale retorting are that upflow retorting continues to have an advantage because rich oil shale easily agglomerates under pressure at retorting temperature; in the upflow retort, pressure is low in the top of the bed where the shale reaches maximum temperature. The char left on the shale after retorting is an uneconomic source of hydrogen; however, the char can be burned in a cocurrent flow combustion to supply all of the plant fuel and most of the power demand. Early steps in developing reactor concepts, moving-bed pilot-plant experiments with separate char combustion to keep flue gases out of the retort, tests of shale compressibility, and process factors causing agglomeration are discussed.
