Abstract
542,500. Naphthenic hydrocarbons. ANGLOIRANIAN OIL CO., Ltd., FAWCETT, E. W. M., and STEINER, H. M. E. April 2, 1940, No. 5945. [Class 2 (iii)] Paraffin hydrocarbons containing 5 or more carbon atoms in the molecule are converted into naphthenic hydrocarbons by a two-stage continuous process which comprises a first stage in which the paraffin hydrocarbons are contacted with chromic oxide or molybdic oxide or other known dehydrogenating catalyst of Sub-group A of Group III of the Periodic Table at a temperature within the range 400‹-700‹ C. under a pressure in the range 1-100 atmospheres, to produce a re-action product comprising aromatic hydrocarbons and hydrogen, and a second stage in which the re-action product is contacted with a hydrogenating catalyst under conditions of -temperature and pressure favourable to the conversion of the re-action product into naphthenic 'hydrocarbons. If desired additional hydrogen may be added after the first stage and before the re-actants are passed to the second stage. The second stage is preferably carried out at a temperatures of 100‹-400‹ C. and a pressure of 1-100 atmospheres. ' The catalysts used for this second stage are of two types (1) a metal such as finely divided nickel or copper which may be supported on a porous carrier such as kieselguhr or alumina gel in which case the treatment is carried out at 100‹-300‹ C. and at pressures of 1-50 atmospheres. (2) A sulphurresistant metallic oxide or sulphide such as molybdic oxide or molybdenum disulphide, or mixtures such as mixed nickel or tungsten sulphides in which case the treatment is carried out at 200‹-500‹ C. and at pressures of 10-500 atmospheres. The catalysts may either be used in the form of pellets or incorporated with porous carriers such as active carbon. In an example, paraffin hydrocarbons or materials containing paraffin hydrocarbons are passed through a re-action vessel containing chromic oxide gel at a temperature within the range 400‹-700‹ C. under a pressure in the range 1-100 atmospheres. The re-action product comprising aromatic hydrocarbons and hydrogen is passed over a hydrogenation catalyst to yield the required naphthenic hydrocarbons. The Provisional Specification describes also conditions of operation of the second stage of the process whereby a product is obtained which does not consist wholly of naphthenic hydrocarbons but contains aromatic hydrocarbons.
