Claim 1

A PROCESS FOR THE PRODUCTION OF OXYGENATED PRODUCTS INCLUDING ALCOHOL FROM AN OLEFINIC PETROLEUM FRACTION, NATURAL GAS, AND OXYGEN THROUGH THE TWO-STEPS OXO SYNTHESIS, WHICH COMPRISES THE STEPS OF COMBUSTING NATURAL GAS WITH OXYGEN UNDER CONDITIONS TO PRODUCE A SYNTHESIS GAS CONSISTING PREDOMINANTLY OF HYDROGEN AND CARBON MONOXIDE IN A MOL RATIO OF AT LEAST 1.5:1, REACTING SAID OLEFINIC PETROLEUM FRACTION IN THE FIRST STEP OF THE OXO SYNTHESIS WITH A COBALT CATALYST AND WITH A SYNTHESIS GAS DERIVED AS HEREINAFTER SPECIFIED AND CONSISTING PREDOMINANTLY OF HYDROGEN AND CARBON MONOXIDE IN A MOL RATIO BELOW 1.5:1 TO PRODUCE A LIQUIID PRODUCT CONTAINING ALDEHYDES, HYDROGENATING SAID LIQUID PRODUCT IN THE SECOND STEP OF THE OXO SYNTHESIS IN A SEPARATE ZONE WITH A SULF-ACTIVE HYDROGENATION CATALYST AND WITH SAID SYNTHESIS GAS CONSISTING PREDOMINANTLY OF HYDROGEN AND CARBON MONOXIDE IN A MOL RATIO OF AT LEAST 1.5:1, SAID SYNTHESIS GAS BEING APPLIED IN AN AMOUNT IN EXCESS OF THE AMOUNT CONSUMED IN SAID HYDROGENATION, AND UTILIZING THE UNREACTED EXCESS SYNTHESIS GAS FROM SAID HYDROGENATION STEP AS THE AFOREMENTIONED SYNTHESIS GAS REACTED WITH SAID OLEFINIC PETROLEUM FRACTION IN SAID FIRST SYNTHESIS STEP, AND RECOVERING OXYGENATED PRODUCT INCLUDING ALCOHOL FROM THE PRODCUT OF SAID SECOND SYNTHESIS STEP.
