Catalytic Methane Conversion

Catalytic Methane Conversion: The direct oxidative conversion of methane to an easily transportable liquid such as methanol has been regarded as a 'Holy Grail' in the chemical industry. Methane, as the most abundant and low-cost hydrocarbon feedstock, is also the biggest non-CO2 greenhouse gas, yet its global warming potential is estimated to be 21 times more than CO2. The effective methane utilization could have tremendous economic and environmental benefits.

Developing low-cost methane to liquid conversion chemical processes has been one of the main focuses of SHEETA. Through several years R&D activities, we have made significant breakthroughs in gas to liquid conversion technologies. Specifically, we have demonstrated that our semi-hydrated solid oxidant combined with our methane-activation catalyst can partially oxidize methane to yield methanol, carbon monoxide and hydrogen.

A United State provisional patent has been filed to protect this innovative discovery. This invention is a one-step process of converting CH4 to CH3OH using a solid oxidant/catalyst system. The basic concept of using a solid catalyst to convert CH4 to CH3OH at the temperature lower than 500 °C is new. This patent process can be used for removal of CH4 in a wide range of applications. The field applications include, but not limited to:

  • Natural gas production,
  • Refinery process stream,
  • Coal-bed methane,
  • Oil and gas refinery waste streams,
  • Landfill operations.

Advantages of Our Technologies

  • A single pass direct conversion of methane (no Fischer-Tropsch process)
  • Process temperatures of 200-500°C
  • Greater than 95% selectivity for methanol and current yields of 50%.
