Small particle low fluoride content catalyst

摘要

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. The catalyst is also useful for waxy distillate and waxy raffinate isomerization.
