Abstract
A catalyst comprising at least one metal selected from the group consisting of rhodium, palladium, ruthenium, iridium and platinum in combination with a Group VB element supported on a porous carrier is employed in the hydrocracking of heavy aromatic hydrocarbons using steam as the hydrogen source. The product consists mainly of hydrogen, carbon dioxide and lower molecular weight aromatic hydrocarbons. The catalyst is especially useful for the dealkylation of aromatic hydrocarbons.
Claims6
A hydrocarbon conversion process which comprises comingling water with said hydrocarbon in a molar ratio ranging from 1.0:1 to 20.0:1, heating the mixture at a temperature of from 300.degree. to 600.degree. C., at a pressure of from 0-1500 psig, in contact with a catalyst composition consisting of a Group VIII metal selected from the group consisting of rhodium, palladium, ruthenium, iridium and platinum in combination with a Group VB element, said Group VB element and metal being deposited on an alumina support.
