Small particle low fluoride content catalyst and wax isomerization using said catalyst

Abstract From the Canadian patent

A noble Group VIII metal on low fluoride content small particle size refractory metal oxide isomerization catalyst is disclosed. The catalyst is characterized by having a fluoride content in the range of 0.1 to up to but less than 2 wt%, preferably 0.1 to 1.5 wt%, more preferably 0.2 to 1.0 wt%, a particle diameter of less than 1/16 inch and a preferred noble Group VIII metal loading in the range of 0.1 to 2.0 wt%. The preferred small particle support is 1/20 inch trilobe alumina. The catalyst has been found to be useful for wax isomerization demonstrating excellent selectivity to oil boiling in the lube oil range while also having acceptable activity.
