ResumoThe M. W. Kellogg Company had collaborated in studies of Kellogg's “Synthol” process, an American version of Germany's wartime Fischer–Tropsch synthesis, converting synthesis gas (hydrogen and carbon monoxide) to gasoline. Indiana and Kellogg had exchanged data from pilot plant Synthol reactors, “stationary” fluid beds operating in the bubbling regime: Stanolind, an Indiana subsidiary, had a unit 8 inches in diameter in Tulsa, Oklahoma; and Kellogg had a 2-inch unit at its laboratory in Jersey City, New Jersey. In early fluid crackers, regeneration had produced more heat than the cracking bed could use, and catalyst undergoing regeneration was circulated through a catalyst cooler and back to the regeneration bed. Kellogg's fast-bed reactors for Sasol received negligible attention in the European or U.S. engineering literature, and Sasol's engineering achievements in implementing Kellogg's concept attracted little notice. A major difference between the Lurgi and Sasol fast-bed designs is that the former displays a large gradient in solid density, while the Sasol design is capable of achieving something much closer to uniform catalyst density throughout its height. This chapter reports the contributions of the Institute of Chemical Metallurgy fluidization research team toward understanding and applying the fast fluid bed.
