Abstract
The possibility of fine purification of hydrogen from CO by means of preferable hydrogenation of carbon(I) monoxide into methane till the residual CO content of 1000 ppm is investigated. In order to develop a compact device intended for hydrogen preparation for fuel elements, an efficient nickel-containing catalyst was proposed that provides the required purification degree (not more than 1000 ppm CO at the outlet), selectivity (not less than 70 % of methane is formed from CO) and the level of activity (contact time is not more than 6000 h-1).
