ABSTRACT:
Hydrocarbon oils, particularly oils which have a high boiling temperature, are treated to remove organic sulphur compounds by subjecting a mixture of a hydrogenating gas, e.g. a gas containing at least 90% v/v hydrogen and is substantially free from carbon oxides, and partially vaporized oil to a hydrogenation reaction over a known hydrogenation catalyst and thereafter passing the resulting liquid/vapor mixture which also contains hydrogen sulphide over zinc oxide, thereby to remove the hydrogen sulphide.
