Abstract

Crude liquid hydrocarbons of the paraffin or naphthene series are purified by the process described in the parent Specification in which the hydrocarbons are treated with dilute nitric acid, preferably 2-15 per cent, or with small amounts of nitrogen oxides in the presence of water, at a temperature of 50 to 90 DEG C., the purified oil being subsequently treated with alkali or with concentrated sulphuric acid. Petroleum fractions such as heavy or middle oils, gas oil, oils containing solid hydrocarbons, or the products of low temperature carbonization or destructive hydrogenation of coals, tars &c. are thereby freed from unsaturated hydrocarbons, asphaltic substances and organic sulphur compounds. 1500 parts of Russian gas oil are stirred for 3 hours at 90 DEG C. with 5 per cent nitric acid. After cooling, the oil layer is separated, treated with concentrated sulphuric acid and washed. Such purified oils are suitable for oxidation treatment, for example with air, oxygen or nitrogen oxides in the presence of catalysts, e.g. magnesium stearate.
