Method, and an arrangement, for producing synthesis gases

摘要

In a method for the production of synthesis or reduction gases from carbonaceous fuels and oxygen-containing gases endothermally reacting with the fuels, the starting products are reacted in a plasma reaction zone. In order to provide a method by which the production of reduction gases is feasible up to the highest flow rates in an operationally safe manner and by an optimum utilization of the energy supplied, the components to be reacted are commonly conducted through an elongate reaction chamber as a feed fluid. A central plasma jet is formed over the total longitudinal extension of the reaction chamber. The arrangement, i.e., the elongate reaction chamber, includes a plasma electrode (cathode) on one end and a counter electrode (anode) on the other end; supply ducts for the feed fluid and discharge ducts for the synthesis or reduction gases in the region of the plasma electrode end are provided.
