Abs., vol. 30, 1936. p. 7835. Hydrocarbons of higher molecular weight than bezine, for example, paraffin waxes and lubricating oils, are obtained by the catalytic reaction of CO and H2 at <375° and >20 atm. pressure in a hydrocarbon medium that remains liquid under the reaction conditions. The products may be separated from the medium by distillation or by extraction with SO2 or other solvent. In an example, a mixture of CO with a large excess of H2 is heated to 250° under 50 atm. pressure with anthracene oil in which a catalyst comprising ZnO, MgO and Fe is suspended: a mixture of hydrocarbons, mainly paraffin wax and lubricating oil, is recovered from the product. |
