    • Novel gas-contacting electrodes for use in continuous electrochemical reactors with gaseous reactants to obtain gas or liquid products, and process for making such gas-contacting electrodes comprising the steps of forming a porous matrix by applying a mixture of a catalyst, a hydrophobe and a micro-sized pore-former onto a substrate; and treating the matrix to remove the pore-former. The removal of the pore-former may be by any one of the dissolution, decomposition, vaporization and reaction of pore forming particulates. The pore-former may be any compatible solid that can be removed from the matrix by dissolution, decomposition, vaporization or reaction, preferably in solid particulate form characterised by a particle size range and distribution that correspond to the desired pore size in the finished electrode. In some embodiments, the particle size of the pore-former in the mixture may be between 1 micrometer to millimeter.

    • In previously known apparatuses using CO or synthesis gas, where a hot particle flow is supplied into a converter in form of an aerosol, incomplete chemical conversion in the converter may occur. Furthermore, heat losses may occur, which compromises efficiency, and particles may deposit, which leads to interruptions during operation. These problems are solved by a C-converter comprising at least one aerosol converter inlet for an aerosol comprising a first gas and particles containing carbon; at least one converter gas inlet for a second gas; at least two converter chamber outlets and at least two converter chambers which are adapted to be filled with particles between a minimum and a maximum particle filling degree. The C- converter further comprises at least one diverting device which is adapted to selectively connect a fraction of the converter chambers a) to at least one of the aerosol converter inlets for aerosol or b) to at least one of the converter gas inlets for the second gas or may disconnect the converter chambers therefrom; and at least one discharging device which is adapted to selectively connect a fraction of the converter chambers to at least one of the converter outlets or to disconnect the converter chambers therefrom. Aerosols containing particles may be converted by means of the C-converter without interruption, and a high conversion degree of the materials supplied into the converter is obtained. Furthermore, an apparatus for producing CO or synthesis gas is disclosed, wherein the C-converter may be used. Methods for operating the C-converter and the apparatus for producing CO or synthesis gas are also disclosed.
