Preparation of catalysts for alkane/cycloalkane isomerization

摘要

A material which is effective as a catalyst for isomerizing alkanes and/or cycloalkanes is prepared by a method which comprises incorporating Nb and/or Ta into a reduced material comprising Pt and/or Pd on alumina, followed by heating in a non-reducing gas and heat-treatment with at least one fluoroalkane and/or chlorofluroalkane (preferably CClF3).
