Non Thermal Plasma Assisted Catalytic Reactor for CO2 Methanation
Project Description
In situ production of methane as propellant by methanation of CO2, also called Sabatier reaction, is a key enabling technology required for sustainable and affordable human exploration of Mars. The Sabatier reaction is conventionally carried out in a fixed bed catalyst at high temperatures of 350-400 ?C. For the long duration future Mars missions (~ 18 months expected stay on Mars), the fixed bed Sabatier reactor design however is inadequate due to performance and catalyst durability issues. In addition thermal management within the reactor is a major issue due to exothermicity of the reaction. Lynntech has demonstrated the feasibility of a novel low power, low temperature plasma assisted catalysis process for addressing these limitations with the methanation of CO2 at a scale of 14 g/h methane production rate. In the Phase II project, Lynntech proposes to build and demonstrate a full scale (0.55 kg/h methane production rate) Sabatier reactor for NASA application. The anticipated Technology Readiness Level at the beginning and ending of Phase II will be 3 and 4, respectively.

Anticipated Benefits
Lynntech's non thermal plasma assisted Sabatier reactor technology provides an energy efficient, low temperature and durable product for the generation of methane from CO2 for following NASA applications: (1) Propellant production on Mars from the Martian CO2, (2) Atmospheric revitalization of the cabin environment for utilization of CO2 in the cabin.
The Sabatier technology can be used for CO2 sequestration or as an intermediate processing technique for fuel or chemical production in the commercial market. The primary and sub-markets for Lynntech's Sabatier technology are as follows: (1) CO2 sequestration with SNG formation for a number of areas including power plants and petrochemical industry. (2) CO removal (specific methanation) technology for purification of reformate or hydrogen streams from fuel reformation. (3) Reformation processes such as dry reforming of methane with CO2. The plasma assisted catalytic reactor design has several applications in following areas: (1) Gas purification (such as impurity removal from biogas, natural gas, LPG, etc.), (2) Diesel exhaust gas purification for NOx and SOx abatement, (3) Fuel reformation for hydrogen generation and (4) Sluggish catalytic reactions requiring high activation energies.
