Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
37 words
A catalyst composition comprising shaped catalytic bodies including (1) rods of dispersed fibrous form imogolite; (2) at least one inorganic oxide gel, said gel bonding said rods together in substantially random mutual orientation in said catalytic bodies.
Claim 2
Dependent Claim
37 words
A catalyst composition comprising shaped catalytic bodies including (1) rods of dispersed fibrous form imogolite; (2) at least one inorganic oxide gel, said gel bonding said rods together in substantially random mutual orientation in said catalytic bodies.
Claim 3
Dependent Claim
28 words
A catalyst according to claim 1 wherein said inorganic oxide gel is present in said composition in an amount between 10 and 50 weight percent of said rods.
Claim 4
Dependent Claim
28 words
