Abstract: A metal oxide nanotube-supported gold catalyst and a preparing method thereof are disclosed. The metal oxide nanotube-supported gold catalyst includes a metal oxide support and a plurality of gold particles loaded into the metal oxide support, and there are at least two gold species with different oxidation states are loaded into the metal oxide support. The preparing method of the metal oxide nanotube-supported gold catalyst includes the deposition of the gold particles on the surface of the metal oxide nanotubes by using an ion exchange reaction.

Abstract: A naphtha upgrading process is provided which process utilizes a sulfated solid catalyst comprising (1) oxide or hydroxide of Group III or Group IV element, e.g. zirconium, and (2) a first metal comprising a metal or combination of metals selected from the group consisting of platinum, palladium, nickel, platinum and rhenium, and platinum and tin. The sulfated support is calcined prior to incorporation of the first metal and subsequent to said incorporation. The catalyst may further comprise (3) a second metal selected from the group consisting of Group VIII elements, e.g. iron. One embodiment of the invention further comprises (4) a third metal selected from the group consisting of Group V, VI and VII elements, e.g. manganese. Said second and third metals are added prior to the first calcination.
