ABSTRACT:
Process for producing gasoline components from a hydrocarbonaceous feed containing hydrocarbons comprising at least 4 carbon atoms, and hydrocarbons obtained thereby. The process comprises:
a. separating feed into a heavy fraction containing hydrocarbons comprising at least 7 carbon atoms and a light fraction containing hydrocarbons comprising at most 7 carbon atoms,
b. isomerizing at least part of the light fraction at a temperature between 50.degree. and 300.degree. C.,
c. separating effluent of step b) into a stream containing branched hydrocarbons and a stream containing normal hydrocarbons, and
d. isomerizing at least part of the stream containing normal hydrocarbons at a temperature which is higher than the temperature applied in step b).
