Abstract

Soot removal process at or inside a synthesis gas- and/or CO-containing gas production apparatus using as feed gases carbon dioxide, steam, hydrogen and/or a hydrocarbon-containing residual gas and using electrical energy in RWGS processes, electrolyses for electrochemical decomposition of carbon dioxide and/or steam, reforming operations and/or synthesis gas production processes with at least one gas production unit, an electrolysis stack and/or a heater-reactor combination for performing an RWGS reaction and at least one cooling sector/recuperator for CO-containing gas and/or synthesis gas, and also a soot removal assembly. Formation of soot can be suppressed or prevented during gas cooling and soot that is nevertheless deposited can be removed again from the heat exchanger surface.
