28 A B S T R A C T METHOD FOR TREATMENT OF A GAS A METHOD OF TREATING OFF-GAS FROM A FISCHER-TROPSCH REACTION IS DISCLOSED, THE METHOD COMPRISING THE STEPS 5 OF: W RECOVERING THE OFF-GAS FROM A FISCHER-TROPSCH REACTION, AND (II) HYDROGENATING A PORTION OF THE OLEFINS PRESENT IN SAID OFF-GAS. IN PREFERRED EMBODIMENTS THE HYDROGENATED OFF-GAS IS USED AS A FEED FOR A HYDROGEN MANUFACTURING UNIT -10 BASED ON STEAM REFORMING. CARBON MONOXIDE CAN BE OXIDISED OR METHANATED. A CUO/ZNO BASED CATALYST CAN BE USED TO HYDROGENATE THE OLEFINS. THE PRESENT INVENTION ALLOWS FISCHER-TROPSCH OFF-GAS (CONTAINING UNCONVERTED SYNGAS, OLEFINS, CL-C4 HYDROCARBONS AND INERTS) TO BE 15 RECYCLED WHICH IS MORE EFFICIENT THAN USING IT AS FUEL. FIQ. 2
