Zusammenfassung: | The invention relates to a process for preparing highly pure hydrogen employed in the supply of fuel cells and to a device for carrying out said process. According to the invention, the process consists in steam reforming the methane or natural gases, followed by the steam conversion of CO into COand hydrogen purification with selective membranes of palladium alloy until reaching a CO content of 1 ppm, at the most. The device claimed by the invention consists of a unit for catalytic reforming of methane using steam, said unit comprising a reactor and a hydrogen advanced purification unit.
Invenţia se referă la un procedeu de obţinere a hidrogenului ultrapur, utilizat pentru alimentarea pilelor de combustibil, şi la un dispozitiv pentru aplicarea procedeului. Procedeul conform invenţiei constă din reformare cu abur a metanului sau gazelor naturale, urmată de conversia cu abur a CO la CO, şi purificarea hidrogenului cu membrane selective din aliaj de paladiu, până la un conţinut de CO de maximum 1 ppm. Dispozitivul conform invenţiei este format dintr-o unitate de reformare catalitică a metanului cu abur, constituită dintr-un reactor şi o unitate de purificare avansată a hidrogenului. |
