| titleOfInvention | Improvements in or relating to hydrofining cracked petroleum hydrocarbons |
| abstract | Cracked petroleum hydrocarbons boiling below 700 DEG F. are mildly hydrofined by contacting with added hydrogen in the presence of a hydrofining catalyst, at a temperature of 400-700 DEG F., a pressure of 50-250 p.s.i., a feed rate of 1-20 v.v./hr. and a hydrogen consumption of not more than .60 standard cubic feet per barrel; the bromine number is thus reduced by not more than 33 per cent. Catalysts specified are cobalt molybdate supported on alumina and a mixture of tungsten and nickel sulphides. Dilute hydrogen from a hydroformer, containing for example 50-100 per cent hydrogen, may be used. The treated hydrocarbons may be washed with caustic soda or steam stripped. In examples, the hydrofining of thermally cracked virgin naphtha and of a catalytically cracked light naphtha of boiling range 130 DEG -330 DEG F. is described; mixtures of thermally and catalytically cracked naphthas may also be treated. Specification 711,259 is referred to. |
