Title: Hydrocarbon conversion catalyst and the uses thereof
IPC: B01J23/46
Filed: 1974-06-28
Abstract: 1474284 Catalytic hydroforming of hydrocarbon feedstocks EXXON RESEARCH & ENG CO 28 June 1974 [19 July 1973] 28783/74 Heading O [Also in Division B1] Hydrocarbon feeds are converted in the presence of a catalyst comprising at least 0À1% wt. of platinum, at least 0À1% wt. of iridium and at least 0À05% wt. of rhodium on a refractory oxide support wherein the noble metals are present as polymetallic clusters with a total metal carbon monoxide chemisorption surface area of at least 200 m<SP>2</SP>/g. The conversion process may be reforming using a halogen-containing catalyst containing less than two atoms of sulphur per atom of noble metals and being substantially free of alkali or alkaline earth metal constituents. Naphtha hydroforming of a substantially sulphur-free feed containing 10-80 vol. per cent paraffins, 10-80 vol. per cent naphthenes and 2-20% aromatics and boiling at 80-450‹ F. is described using vapour phase reaction at 650-1000‹ F., 1-50 atmos. pressure, a space velocity of 0À5-20 hr.<SP>-1</SP>, and a hydrogen to hydrocarbon mole ratio of 0À5- 20. The hydrogen employed may be in admixture with light gaseous hydrocarbons and hydrogen recycle is used. The catalyst may be maintained as a fixed bed in a series of adiabatically operated reactors, with product stream reheat between reactors. Alternatively, a moving or fluidized bed of catalyst may be used. The catalyst is particularly effective for the dehydrocyclization aspect of reforming to convert paraffins to armatics and, accordingly, may be used in the final reactors of a reactor series to convert paraffins to aromatics after naphthenes have been converted to aromatics using a platinum on alumina catalyst. The reforming may be effected in a semi-regenerator manner with the temperature being increased as coke build-up deactivates the catalyst, followed by catalyst regeneration when a reactiontemperature of 1000‹ F. is reached.  The use of the catalyst for dehydrocyclization of paraffins or naphthenes at 700-1000‹ F. and a pressure of less than 10 atmospheres in the presence of hydrogen and for the isomerization of ethylbenzene to xylenes at 400-1100‹ F. at elevated pressures in the absence of hydrogen are also described.
