ELECTROLYSER AND METHOD FOR PRODUCING SYNTHESIS GAS BY WATER ELECTROLYSIS USING GRAPHITE/CARBON ELECTRODES

摘要

The present invention relates to an alkaline electrolyzer, characterized in that the electrolysis is carried out without separation of hydrogen and oxygen gases obtained from the dissociation of water. The electrodes are of graphite (2), isolated by separating plates (1), immersed in a tank (5) duly sealed containing deionised water to which is added an electrolyte of sodium hydroxide at low concentrations; the terminal electrodes are the positive(4) and negative pole (3). The graphite plates (2) have two holes each, creating two flow channels of the electrolyte, with the lower channel (6) connected to the inlet of the electrolyte , while the upper channel (7) corresponds to the outlet of the electrolyte channel, dragging the gases produced in the electrolysis and in the oxidation process. The present invention also relates to an electrolysis process carried out in the electrolyzer constructed in accordance with claim No.1, powered by an electrical energy source, obtaining a mixture of gases containing hydrogen and oxygen, which are piped towards a catalyst reactor with the carbonaceous material to produce synthesis gas.
