Abstract:
A process for the conversion of a material selected from a wax, a polymer and an oligomer, said polymer and said oligomer deriving from an ethylenically unsaturated monomer, into alkanes or a hydrocarbon fraction or an oligomer fraction of the lower variety by controlled hydrocracking, comprising the following steps:bringing the wax or polymer or oligomer into the presence of a catalyst which is either a metal hydride supported on an inorganic support or an organometallic complex supported on an inorganic support, said inorganic support being a divided solid comprising a metal oxide or a mixture of metal oxides, said complex including at least one hydrocarbon ligand, and optionally at least one hydride ligand, thenreacting this mixture with hydrogen, thus catalytically hydrocracking said polymer or oligomer,and recovering said alkanes hydrocarbon fraction or oligomer fraction of the lower variety.
