1291047 Converting cyclic hydrocarbons to paraffins SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 6 April 1970 [7 April 1969] 16206/70 Heading C5E Cyclic hydrocarbons, particularly alkyl-cyclopentanes, are converted to paraffins by contact in the presence of hydrogen with a catalyst comprising (1) Rh and/or Ru, and (2) a halogen promoted refractory oxidic support. Preferred conditions include temperatures from 204- 399‹ C., pressures from 35-105 atm. gauge, H 2 : hydrocarbon mole ratio from 5 : 1 to 15 : 1, and a space velocity of 1-20 wt./hour/wt. of catalyst. Examples illustrate conversion of methyl-cyclopentane to mainly C 6 paraffins, the selective conversion of methyl-cyclopentane in the presence of cyclohexane, and the conversion of the raffinate fraction obtained after extracting benzene from a reformate. |
