ABSTRACT:
The present process has for object the manufacture of olefinic hydrocarbons with respectively 2 and 3 carbon atoms per molecule. This object is attained by treating a charge selected from such cuts as light or heavy naphthas, kerosenes and light gas oils of distillation point lower than 360.degree. C. The cut is subjected to hydrogenolysis and the resulting C.sub.2 and C.sub.3 hydrocarbons are fed to a steam-cracking plant, while the C.sub.4.sup.+ hydrocarbons are subjected to further hydrogenolysis.
