Direct insertion of methane into C 3–C 4 paraffins over zeolite catalysts: a start to the development of new one-step catalytic processes for the gas-to-liquid transformation

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 proc...

Summary: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.
