3319. SEGURA, M. A.,AND MCADAMS, D. R. (Standard Oil Development Co.). process of Reclaiming a Contaminated Iron Catalyst. United States Patent 2,483,850, Oct. 4, 1949; appl. filed July 23, 1947, Serial No. 763,106; 4 claims (Cl. 252-417). Chem. Abs., vol. 44, 1950, p. 2206.

Carbonaceous contaminant is burned from the Fe catalyst at 1,000°-1,150° F., until the catalyst does not contain more than 30 nor less than 5 wt. % carbonaceous material. The treated catalyst is cooled to a temperature below the b. p. of H₂O. It is mixed with enough H₂O to form a moist, loosely compacted mass. The mass is sintered at 2000°-2200° F. for 0.5-2.0 min. quenched, and reground. 2 United States patents cited.
