Selective ring-opening way of naphthenic ring

摘要

(57) and containing at least one ₅ ring C having at least one substituent, further, cyclic compounds, some to ₅ ring C having the substituent at least present in [Abstract] The feed stream is at least 8 carbon atoms, the average number of carbon atoms, the selective opening of the naphthene ring method of naphthenic ring-containing compound in the feed stream.₅ naphthene ring this C is opened without dealkylation significantly pendant all substituents of the ring. It is contacted with a catalyst comprising a metal selected effective amount of the the catalyst carrier on, and mixtures thereof, as well as Rh Ir, and Ru, further, the hydrocarbon feed stream containing such compounds, the When it is reacted with the feed consisting of 20 wt% in heptane diluent from n- pentyl-cyclopentane, catalyst, to C ₁₀ paraffinic product of at least 0.80 and C ₁₀ paraffins RuiOsamu-ritsu at least 25% selectivity (However, selectivity is defined by the C ₁₀ ring disappearance% C ₁₀ paraffin RuiOsamu-ritsu /%) would be.
