Abstract

An object of the present invention is to provide a non-equilibrium plasma (NEP) system and method of refining syngas. In accordance with an aspect of the present invention, there is provided a non-equilibrium plasma system for refining syngas, the system comprising a reactor with a hollow chamber, having one or more inlet manifolds configured to promote an axially symmetric and swirling flow pattern, into which syngas and one or more gasifying agents are introduced for processing within the reactor, a high voltage electrode; and a ground electrode, wherein the system is configured to create a non-equilibrium plasma producing electric arc upon application of a high voltage potential across an arc initiating gap between the high voltage electrode and the ground electrode and wherein the system is configured such that the syngas, the one or more gasifying agent(s) and plasma producing electric arc come together concurrently in the reactor. In one embodiment of the invention, the non-equilibrium plasma system comprises two eccentric cylindrical manifolds configured to form a single inlet manifold, wherein the two eccentric cylindrical manifolds comprise a first eccentric cylindrical manifold for gasifying agent input and a second eccentric cylindrical manifold for syngas input. The invention also comprises a method for refining syngas wherein the non-equilibrium plasma system of the present invention combines the syngas, the air and the plasma-producing electric arc in the same region, which will co-exist in the same location.
