Abstract
Cracked, sour raw naphtha, which has not received any chemical treatment to remove H2S and cresols, is purified by adding 2-20 pounds of a phenylene diamine per 1,000 barrels of naptha, contacting the mixture with an aqueous solution containing 10-50 per cent of an alkali metal hydroxide, in the presence of free oxygen in an amount which is the stoichiometric equivalent to the mercaptan sulphur in the naphtha, and separating the naphtha from the aqueous phase. Phenylene diamines referred to are N, N1-di-secondary-butyl, N, N1-di-iso-propyl, N, N1-di-amyl, N, N1-dihexyl, N-propyl-N1-butyl, N-butyl-N1-amyl and N-hexyl-N1-octyl phenylene diamines. Air or oxygen itself may be used to supply the free oxygen. Alkalis mentioned are sodium and potassium hydroxides. The raw naphtha may be derived from thermal cracking or reforming or catalytic cracking. Examples are given of the treatment of a naphtha boiling between 130 DEG and 400 DEG F. derived from the catalytic cracking of a gas oil, and of mixtures of this naphtha with a mixture of virgin and thermally cracked naphthas.
