Embodiment

[0064] To better understand the processes taking place inside the plasma torch, Computational FluidDynamics (CFD - Computational Fluid Dynamics ) mock resource. The provided showed good energy efficiency in hydrogen production, however, the CO 2 conversion rate is low. In terms of efficiency and scale, the electric arc thermal plasma torch is in the conversion of natural gas to CO 2 Excellent results were achieved in plasma.

Abstract

The present invention describes a plasma reactor for processing natural gas and / or light hydrocarbons, including biomethane and biogas, using a plasma torch that does not require the use of cathode-protection gas (shielding gas), and also a reforming process involving the use of a plasma reactor for the production of synthesis gas and carbonaceous materials from natural gas and / or light hydrocarbons.

Description

technical field [0001] The present invention relates to a method and a reactor for the production of synthesis gas. More specifically, the present invention proposes a reactor utilizing electric discharge and carbon dioxide, and a reforming process using this reactor for the production of synthesis gas with high thermal power and nanostructured carbon. Background technique [0002] Large-scale production of hydrogen and hydrogen-rich gases (called synthesis gas) for the refining industry, for the production of ammonia, methanol, liquid hydrocarbons from the "Fischer-Tropsch" process, for several A petrochemical method and a hydrogenation method. To obtain it, some hydrocarbon reforming (eg natural gas and / or other light hydrocarbons) processes may be used, such as steam reforming, partial oxidation, autothermal reforming or dry reforming. Currently, the steam reforming process of natural gas (methane and / or other light hydrocarbons) is the most common method for producing ...
