Process for reducing organic compounds by hydrogenation

Claim 1

IN BATCH-WISE PROCESSES FOR THE CATALYTIC HYDROGENATION OF FATTY MATERIALS UNDER HEAT AND HYDROGEN PRESSURE THE IMPROVEMENT WHICH COMPRISES, MAINTAINING THE TEMPERATURE AND THE HYDROGEN PRESSURE IN THE REACTION ZONE AT OPERATING LEVELS BETWEEN RUNS AS WELL AS DURING THE RUNS, AND CONTINUOUSLY DURING EACH RUN INTRODUCING HYDROGEN GASES IN EXCESS INTO AND THROUGH THE REACTION ZONE, VAPORIZING VOLATILE REDUCTION PRODUCTS FROM THE REACTION MASS WHILE LEAVING REDUCED FATTY MATERIALS IN LIQUID FORM IN THE REACTION ZONE, REMOVING THE RESULTING VAPORS FROM THE REACTION ZONE IN ADMIXTURE WITH UNABSORBED HYDROGEN GASES, CONDENSING AND REMOVING THE VOLATILE REDUCTION FROM THE MIXTURE BEFORE REINTRODUCING THE SEPARATED HYDROGEN AGAIN INTO THE REACTION ZONE AND WHEN THE HYDROGENATION REACTION HAS GONE TO COMPLETION FLOWING THE REDUCED FATTY MATERIALS FROM THE REACTION ZONE WHILE MAINTAINING THE SAME UNDER THE HYDROGEN PRESSURE EMPLOYED DURING THE REACTION.
