Fe, Ni, and Co exert a catalytic action on mixtures of CO and H2, and this study was to determine if these metals when in contact with gaseous mixtures would give liquid-organic products. A study was made of different mixtures with a hydrated Fe2O3 base consisting of 98 parts anhydrous Fe2O3 and 2 parts of the following: Na2CO3, Li2CO3, CaCO3, SrCO3, BaCO3, MgCO3, ZnCO3, MnCO3, CuCO3, Ag2CO3, Al2O3, Mo2O3, WO2, or SiO2. Of these 15 mixtures, those containing an alkali carbonate (Na2CO3 or Li2CO3) formed organic liquids with gas of composition CO+5H2 under 150 atm. pressure and a flow of 3,000 m.3. All the others gave CH4, CO2, slightly acid H2O and finally C. Five mixtures with a ferric hydrate base were then studied consisting of 98 parts Fe2O3 and 2 parts of the following: K2SO4, K3PO4, KNO3, and K2S. No oil was formed by the K2S catalyzer, but the other catalyzers produced 11 cm.3 per m.3 of gas from the sulfate, 9 cm.3 per m.3 of gas from the phosphate, 13 cm.3 per m.3 of gas from the borate, and 19 cm.3 per m.3 of gas from the nitrate, with gas (CO+5H2) under 150 atm. pressure and a flow of 3,000 m.3. Mixtures were then prepared by precipitating a mixture of Cu nitrate and Fe nitrate with an alkali, adding the precipitant K2CO3 in proportion to the Fe content, and, after drying, submitting the compound to the action of H2 under atmospheric pressure at 200° for 4 hr. and at 300° for 14 hr. in such a manner as to reduce only the CuO but not the Fe2O3. It was shown that the presence of Cu increased the catalytic action of the Fe2O3-K2CO3 couple; the composition of the catalyzer after reduction at 300° was Fe2O3, 49.5%, Cu 49.5%, K2CO3, 1.0%. With this compound a mixture of H2O and different organic liquid products was extracted from the CO+5H2 mixture in the following proportions: (1) Light carburetants (55°-180° fractions of oil) 28.8%, light oil from activated charcoal 5.0%, alcohol in solution 29.0%, or a total of 62.8%; and (2) clear oil, 180°-250°, 14.0%; (3) heavy oil, 250 °-330°, 10.0%; (4) paraffin 7.1%; (5) tar, 2.7%; and (6) fatty acids, distilling at 110°-140° (weak acetic, propionic, and butyric), 3.1%. With the Cu-Fe2O3-K2CO3 catalyzer, it is not possible to lower the temperature and still be assured of regularity of the phenomena of transformation of the mixture of CO and H2. |
