ABSTRACT:
The present invention pertains to a process for the production of hydrogen and carbon dioxide from hydrocarbons involving:a) supplying a gaseous stream of hydrocarbons and a molecular-oxygen containing gas to a first reaction zone having a fluidized bed of partial oxidation catalyst;b) catalytically partially oxidizing the hydrocarbons in the gaseous stream at a temperature in the range of from 700° C. to 1400° C., to form a first effluent;c) supplying a gaseous stream of hydrocarbons, steam and the first effluent to a second reaction zone containing a fluidized bed of steam reforming catalyst;d) catalytically reforming the hydrocarbons fed to the second reaction zone at a temperature in the range of from 200° C. to 700° C.;e) separating hydrogen from the reformed gas by a selective membrane in the second reaction zone; and,f) removing a gaseous stream rich in carbon dioxide.
