Abstract
A process wherein a feed comprising an admixture of liquid hydrocarbon compounds which includes a polynuclear aromatic hydrocarbon compound, or compounds (PNA's) is contacted in the presence of hydrogen over an iron catalyst at temperature sufficient to selectively hydrogenate and hydrocrack, or destroy the PNA's of the admixture without excessively hydrogenating and hydrocracking the non-PNA's of said feed. The process is particularly applicable for the removal of PNA's from reformates, processed naphthas, and other hydroprocessed streams or the like to achieve a lower and more favorable distribution of PNA's in a motor gasoline pool, and further to remove PNA's from prime fuels and heavier hydrocarbon mixtures.
