Abstract
Abstract Superior isomerization performance is obtained with a catalytic composite comprising a Group VIII noble metal and a hydrogen-form crystalline alumino-silicate incorporated with a refractory inorganic oxide. The superior performance is a direct result of the catalyst composite having a surface area of at least 580 m 2 /g. A novel method of preparing an isomerization catalyst having a surface area of at least 580 m 2 /g is presented, along with a novel process for the isomerization of isomerizable hydrocarbons.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
51 words
A process for isomerizing isomerizable hydroca-bons which comprises contacting said isomerizable hydrocarbons in the presence of hydrogen at isomerization conditions with a catalyst composition comprising a Group VIII metal, hydrogen form mordenite and refractory inorganic oxide, with said catalytic composition having a surface area of at least 580 m 2 /g.
Claim 2
Dependent Claim
51 words
A process for isomerizing isomerizable hydroca-bons which comprises contacting said isomerizable hydrocarbons in the presence of hydrogen at isomerization conditions with a catalyst composition comprising a Group VIII metal, hydrogen form mordenite and refractory inorganic oxide, with said catalytic composition having a surface area of at least 580 m 2 /g.
Claim 3
Dependent Claim
21 words
The process of claim 1 wherein the isomerizable hydrocarbons comprise normal paraffins having from 4 to 7 carbon atoms per molecule.
Claim 4
Dependent Claim
82 words
The process of claim 1 further characterized in that the isomerizing conditions comprise a temperature in the range of from about 200° F. to about 800° F., a pressure of from about 100 to about 1000 pounds per square inch, a liquid hourly space velocity of from about 0.5 to about 5 liquid volumes of said isomerizable hydrocarbons per hour per volume of said catalytic composite and hydrogen to hydrocarbon mole ratio of 0.5-5 mole of H 2 /mole of isomerizable hydrocarbon.
