Abstract
A process for the continuous production of hydrogen from methane and/or natural gas and/or methane-rich hydrocarbons and steam at low temperature, using a solid catalyst comprising group VIII metal oxide(s) in two parallel reactors, comprising reducing the solid catalyst in both the reactors by contacting the catalyst with a gaseous feed comprising a reducing agent, contacting a first gaseous feed comprising methane and/or natural gas and/or methane rich hydrocarbons, simultaneously contacting a second gaseous feed comprising steam called Feed-B with the solid catalyst reduced in step-i in a second reactor. while regularly switching over the two feeds, Feed-A arid Feed-B, between the two parallel reactors to obtain a mixed product stream comprising hydrogen from the two reactors.
