Abstract
Abstract A process for disproportionating feed light alkane to obtain higher molecular weight hydrocarbons which comprises contacting the feed light alkane, at elevated temperature and pressure, with a catalyst comprising a molecular sieve composited with a Group VIII noble metal. Preferably the contacting is carried out in the presence of H2O.
