• aromatization

The paper demonstrates that utilization of the well-known concept of the ability of the same catalytic centers to catalyze both forward and backward reactions can result in the development of a process of the direct one-step insertion of methane into heavier hydrocarbons. The insertion seems to proceed as a part of linear alkanes dehydrocyclization reactions at rather mild pressure and temperature conditions (at 773-823 K) over Zn- or Ga-promoted zeolite catalysts. The experimental study of the process evidences in its potential practical applicability for the natural gas-to-liquid conversion.
