Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
185 words
THE METHOD OF HIGH PRESSURE HYDROGENATION WHICH COMPRISES FLOWING FATTY MATERIAL CONTINUOUSLY THROUGH A REACTION ZONE MAINTAINED AT HYDROGENATION PRESSURE AND TEMPERATURE, INTRODUCING A CATALYST INTO THE FATTY MATERIAL, FLOWING HYDROGEN IN EXCESS THROUGH THE FATTY MATERIAL IN SAID REACTION ZONE AT THE PRESSURE AND TEMPERATURE OF THE REACTION ZONE AT A SPEED GREATER THAN THAT OF THE FATTY MATERIAL, THE VOLUMETRIC RATE OF FLOW OF THE HYDROGEN BEING AT LEAST TEN TIMES THE VOLUMETRIC FLOW OF THE FATTY MATERIAL THROUGH THE REACTION ZONE, CAUSING THE FATTY MATERIAL IN SAID ZONE TO FLOW IN A TORTUOUS PATH WHILE MAINTAINING THE HYDROGENATION PRESSURE AND TEMPERATURE THEREIN, SEPARATING THE EXCESS HYDROGEN AND PRODUCTS WHICH VOLATILIZE FROM THE HYDROGENATED FATTY MATERIAL, CONTINUOUSLY FLOWING THE HYDROGENATED FATTY MATERIAL FROM THE REACTION ZONE WHILE MAINTAINING THE PRESSURE IN THE REACTION ZONE, SEPARATING THE VOLATILIZED PRODUCTS FROM THE EXCESS HYDROGEN AND FLOWING THE EXCESS HYDROGEN BACK THROUGH THE REACTION ZONE WHILE MAINTAINING THE HYDROGENATION PRESSURE ON THE HYDROGEN AND SEPARATELY MAINTAINING THE FLOW OF THE FATTY MATERIAL THROUGH THE REACTION ZONE AT A RATE WHICH ACCOMPLISHES THE DESIRED DEGREE OF HYDROGENATION.
