Fischer-Tropsch Synthesis - EFFECT OF NITRIDING ON THREE TYPES OF IRON CATALYSTS

Fischer-Tropsch Processes Investigated at the Pittsburgh Energy Technology Center since 1944

“…The improved American reactors were each designed to produce approximately 500 bbl/day of liquid fuel-a considerable improvement over the German fixed bed reactors that had a capacity of 18 bbl/day per reactor (10). New discoveries of oil in the U.S., Canada, and the Middle East decreased the U.S. government's interest in synthetic fuels via coal gasification, and consequently operation of the demonstration plant in Missouri ended in 1953. Although large-scale Fischer-Tropsch investigations were not being conducted by the U.S. government after 1953, pilot plant research was continued at PETC with emphasis being placed on improving product distribution (67,68), catalysts (2,3,4,7,8,50,71), and reactor design (21,27,36).…”

“…Nitrided Fused Iron. Bench-scale investigations by Anderson et al (3,71) had demonstrated that nitrided iron was a more active F-T catalyst than conventionally reduced iron and that the yields of oxygenates were greatly increased. Since it was of interest to produce a gasoline with a high alcohol content, the performance of nitrided iron in pilot plant units was evaluated.…”

Synthetic Fatty Acid Triglycerides and Natural Drying Oils

“…The most practical of these depend on the preferential i Present address, Consolidated Products Co., Inc., 15 Park Row, New York 38, N. Y. formation of an oxalic acid complex or on the differing properties of the cresol sulfonic acids. Oxalic acid reacts selectively with p-cresol to form an insoluble compound which can be separated and decomposed to yield pure p-cresol (11,21,27,28). The sulfonation of the cresol mixtures yields the mono acids; when steam distillation is applied, the meta acid hydrolyzes to the cresol at 116°to 120°C ., but the para acid does not decompose until a temperature of 133°to 135°C.…”

Potential Function Model of Hydrogen Bonds. II

“…The methods of evaluating the parameters which appear in the potential function, eq. 7, were described in paper I.28 The parameter g in the equation defining n* * = gn (8) was found to be transferable to all X-H-Y systems considered. The values of n used in all calculations given here were obtained from theoretical considerations using the equation29 tih-x = 5.67 X 1 3(///0) • (9)…”
