682. ------. [FISCHER, F., AND PICHLER, H.] (Studien- und Verwertungs-G. m. b. H.). [Process for the Production Paraffin.] German Patent Appl., St. 56,469, filed July 30, 1937 (Cl. IV d-12 o). FIAT Reel B-196, frames 361-364; PB 83,253; TOM Reel 100.

Process in general refers to the production of solid paraffin from CO and H₂ in presence of a catalyst containing Co at < 250º and 2-50 atm. The preferred operating conditions are as follows: Synthesis gas CO: H₂=1:2; catalyst produced by precipitation and consisting of Co-Th-kieselguhr; pressure 5-20 atm. with the gases remaining in the contact chamber for a period proportional to the increase in pressure: for example, at 10 atm., it would remain 10 times as long as at 1 atm.; temperatures 180º-200º. The best yield, 150-160 gm. per m.³ of gas, is obtained under the above conditions.
