Estimating the term…
A supported Lewis acid catalyst system for catalyzing hydrocarbon conversion reactions including cationic polymerization, alkylation, isomerization and cracking reactions is disclosed, wherein the catalyst system comprises an inorganic oxide support having immobilized thereon a least one strong Lewis acid comprising at least one metal salt of a strong Bronsted acid wherein the metal is selected from the group consisting of aluminum, boron gallium, antimony, tantalum, niobium, yttrium, cobalt, nickel, iron, tin, zinc, magnesium barium strontium, calcium, tungsten, molybdenum and the metals of the lanthanide series and wherein the strong Bronsted acid is selected from the group consisting of mineral and organic acids stronger than 100% sulfuric acid.
A supported Lewis acid catalyst system effective for catalyzing hydrocarbon conversion processes comprising an inorganic oxide substrate having immobilized thereon a catalytically effective amount of at least one strong Lewis acid comprising at least one metal salt of a strong Bronsted acid wherein said metal is selected from the group consisting of aluminum, boron, gallium, antimony, tantalum, niobium, yttrium, cobalt, nickel, iron, tin, zinc, magnesium, barium, strontium, calcium, tungsten, molybdenum and the metals of the lanthanide series, and wherein said strong Bronsted acid is selected from the group consisting of mineral and organic acids having a Hammett acidity value of minus 13 or lower.
