Claim 1
Independent Claim
112 words
A RADIATION ISOMERIZATION PROCESS WHICH COMPRISES CONTACTING A HYDROCARBON MIXTURE COMPRISING PARAFFIN HYDROCARBON HAVING IN THE RANGE OF 4 TO 8 CARBON ATOMS AND IN THE RANGE OF 2 TO 20 WT. PERCENT OF A NAPHTHENE HAVING FROM 5 TO 8 CARBON ATOMS, WITH THE RANGE OF 2 TO 200 WT.
