Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
20 words
A method of claim 1 wherein said hydrocarbon product mixture initially contains 0.2 weight percent or less chemically combined chlorine.
Claim 2
Dependent Claim
51 words
A method of claim 1 wherein said contacting is at an hourly rate of contact in volume of hydrocarbon product mixture feed per volume of sieves within the range of about 0.1 to about 5 and said contacting is percolation of said hydrocarbon product mixture through a bed of said sieves:
Claim 3
Dependent Claim
20 words
A method of claim 1 wherein said molecular sieves are chosen from among Zeolite 10X and Zeolite 13X molecular sieves.
Claim 4
Dependent Claim
