“SYSTEM FOTOCATALìTICA OR FOTOELETROCATALìTICA AND PROCESS OF CO OF NATURAL Gas”. Pioneer patent for fotocatalítico and/or fotoeletrocatalítico system of removal of CO in gas of synthesis, gotten for the process of catalytic primary fuel reform. In this system the removal of CO will occur in a photo-reactor and/or a photo-electro-reactor. In both the cases the system must contain a catalyser, called fotocatalisador that will be activated by radiation, natural or artificial, in the visible region of, ultraviolet or the infra-red ray. As much the photo-reactor how much the fotoeletro-reactor could be used in the end of the reform process before or after the PROX as well as before the entrance of the cell the fuel of type PEM or then in both the places. The fotocatalisador will be constituted by a material semiconductor that will be able its a metallic oxide as : TiO~ 2~; SrTiO~ 2~; Fe~ 2~O~ 3~; SnO; ZnO; CdS; CdSe; CdTe; Gap; GaAs; InP; ZnS; ZnSe; CuO; rare land oxides; RuO; Wó; Ru~ 2~O~ 3~; W~ 2~O~ 3~; UO~ 2~; U~ 3~O~ 8~. It could or not be used in the form of mixtures. To these fotocatalisadores metals could be added as : Co, Ni, Cu, Reverse speed, Me, Ru, Rh, GAC, Pd, Pt, Au, W, rare lands. |
