Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
128 words
A PROCESS FOR THE ISOMERIZATION OF A PARAFFIN HYDROCARBON OF FROM 4 TO 7 CARBON ATOMS WHICH COMPRISES CONTACTING THE SAID HYDROCARBON IN THE LIQUID PHASE IN A REACTION ZONE WITH A CATALYST COMPRISING ALUMINUM BROMIDE AT A TEMPERATURE IN THE RANGE OF ABOUT 40* TO ABOUT 120*F., SAID TEMPERATURE BEING BELOW THE BOILING POINT OF THE SAID HYDROCARBON UNDER THE CONDITIONS EXISTING IN THE REACTION ZONE, CONDUCTING A STREAM OF HYDROGEN HALIDE AT A RATE OF ABOUT 200 TO 4000 CF/B. THROUGH THE REACTION ZONE, REMOVING ISOMERIZED PRODUCT VAPORS FROM THE REACTION ZONE BY MEANS OF SAID HYDROGEN HALIDE STREAM AS A STREAM SEPARATE FROM THE CATALYST, WHILE LEAVING THE HIGHER BOILING STRAIGHT-CHAIN HOMOLOGS IN THE REACTION ZONE, AND SEPARATING ISOMERIZATION PRODUCT FROM THE REMOVED HYDROGEN HALIDE.
