Claim 1
Independent Claim

A PROCESSFOR REGENERATING AN IRON CATALYST WHICH HAS BECOME SPENT AS A RESULT OF CONTINUED CONTACT WITH CARBON MONOXIDE AND HYDROGEN IN THE SYNTHESIS OF HYDROCARBONS BY THE REDUCTION OF CARBON MONOXIDE WITH HYDROGEN, WHICH COMPRISES CONTACTING SAID SPENT CATALYST WITH ETHANOL AT A TEMPERATURE OF FROM ABOUT 540* TO ABOUT 700* F. WHEREBY SAID ETHANOL IS CONVERTED INTO ACETONE, SAID PROCESS BEING EFFECTED IN THE ABSENCE OF HYDROCARBON SYNTHESIS, CONTINUING THE TREATMENT OF SAID SPENT CATALYST WITH ETHANOL AT LEAST UNTIL A DEFINE DECREASE IN ACETONE FORMATION IS OBSERVED, AND THEREAFTER CHARGING THE RESULTING TREATED CATALYST TO A SYNTHESIS REACTOR FOR FURTHER CONVERSION OF CARBON MONOXIDE AND HYDROGEN INTO HYDROCARBONS.
