Abstract
1335948 Dehydroisomerizing alkylcyclopentanes TEXACO DEVELOPMENT CORP 19 May 1972 [21 June 1971] 23595/72 Heading C5E Alkylcyclopentanes are dehydroisomerized to aromatic hydrocarbons by contact with a fluorided catalyst comprising 0À01-5 wt. per cent Re, Pt, Pd, Rh or Ru on alumina in the presence of H 2 and a carbon oxide, the latter being introduced to the process at the rate of 5 x 10<SP>-5</SP> to 5 x 10<SP>-3</SP> gram mol. per hour per g. of catalyst. The catalyst may contain 0À5-15 wt. per cent F on Al 2 O 3 support which may also contain thoria, silica, ZrO 2 or TiO 2 . The feed may be a gasoline or naphtha fraction containing C 6 -C 8 alkylcyclopentanes. The reaction may be effected at 750-1000 F. and a H 2 pressure of 200-750 psig. The examples describe the conversion of methylcyclopentane to benzene.
