Title: Hydrocarbon conversion process
Inventor: SANDROCK JOHN DENIS
IPC: C10G35/06
Filed: 1958-05-01
Abstract: A naphtha boiling below 450 DEG  F. is converted to a higher boiling fuel oil by dehydrogenating at a temperature of 700-1450 DEG  F. and a pressure of below 40 p.s.i.a. in the presence of a dehydrogenation catalyst, mixing the product with a substantially saturated mineral oil and passing through a second reaction zone at 400-900 DEG  F. and above 200 p.s.i.a. in the presence of a refractory cracking catalyst and collecting the product. Dehydrogenation catalysts include silver, copper, alloys of chromium and/or nickel and/or aluminium, sponge iron, porous carbon, zinc sulphide, alumina, pumice, oxides of cobalt, chromium, molybdenum, zinc, vanadium, titanium, thorium or cerium, and mixed oxides of cobalt and molybdenum or cobalt molybdate.  The preferred catalyst is 5-15 per cent by weight of cobalt molybdate supported on alumina which may contain up to 6 per cent by weight of silica and containing 0.1 to 4 per cent by weight of a halogen.  Promoters such as potassium may be added. Fixed, moving or fluidized beds can be used.  Hydrogen is preferably present in the dehydrogenation in an amount of from 1000-20,000 SCF/barrel of feed.  Space velocities of 0.1-20 V/V/hr. are used.  The refractory cracking catalyst present in the second reaction zone may be a synthetic catalyst such as silica, silica-alumina, alumina or silica-magnesia, or a natural bentonite or montmorillonite clay which has been calcined and acid or alkali treated.  Zirconia may be added. The temperature should be sufficiently low to prevent the carbon deposition on the catalyst exceeding 0.4 per cent by weight of the feed.  Space velocities of 0.05-40 V/V/hr. can be used over fixed or fluidized beds. Suitable feeds are virgin naphthas boiling up to 450 DEG  F., C1 to C4 constituents are preferably removed.  In a preferred process a single feed is used part only passing through the dehydrogenation zone the product therefrom being recombined with the remaining feed and passed to the second zone.  Products boiling below 350 DEG  F. may be recycled.  In an example a naphtha with an end-point of 430 DEG  F. in which 73.1 weight per cent boiled up to 350 DEG  F. and 26.9 above was dehydrogenated at 1000 DEG  F. and 20 p.s.i.a. over a cobalt molybdate catalyst, mixed with 45 volume per cent of untreated naphtha and contacted with silica-alumina at 600 DEG  F. and 800 p.s.i.a. to give a product of which 54.7 weight per cent boiled up to 350 DEG  F. and 45.3 above.
