NOVELTY - The process comprises conducting a biogas feedstream containing methane through a pressure swing adsorption process unit for resulting an initial methane-rich product stream, conducting a portion of the initial methane-rich product stream to a steam methane reforming zone where it is reacted under steam reforming conditions in the presence of a steam methane reforming catalyst for resulting a conversion of the portion of the methane-rich product stream to a reformate gaseous stream, and recycling a portion of the reformate gaseous stream to a biogas feedstream.    USE - The process is useful for producing hydrogen from a biogas feedstream, where the hydrogen is useful for fuel cell or internal combustion engines and the fuel cell is useful in a fuel cell stack for energy-consuming devices including motor vehicles, recreational vehicles, industrial or construction vehicles, boat or other sea-craft, tools, lights or lighting assemblies, appliances such as a household or other appliance, households, commercial offices or buildings, neighborhoods, industrial equipment and signaling or communication equipment.    ADVANTAGE - The process is capable of energy efficiently producing the hydrogen with high purity.    DETAILED DESCRIPTION - The process comprises conducting a biogas feedstream containing methane through a pressure swing adsorption process unit for resulting an initial methane-rich product stream, conducting a portion of the initial methane-rich product stream to a steam methane reforming zone where it is reacted under steam reforming conditions in the presence of a steam methane reforming catalyst for resulting a conversion of the portion of the methane-rich product stream to a reformate gaseous stream, recycling a portion of the reformate gaseous stream to a biogas feedstream, conducting a mixed stream through the pressure swing adsorption process unit for resulting the methane-rich product stream and a hydrogen-rich product stream, collecting the hydrogen-rich product stream, and conducting the methane-rich product stream to the steam methane reforming zone, where a reformate gaseous stream is produced. The pressure swing adsorption process unit contains a first adsorbent, which is selective for methane and a second adsorbent, which is selective for hydrogen. The reformate gaseous stream comprises hydrogen and carbon monoxide. The biogas is a landfill gas. The steam methane reforming is operated at a temperature 300-900 degrees C and at pressure of 15-150 psig. The hydrogen-rich product stream comprises pure hydrogen as fuel in a fuel cell system and an internal combustion engine as an integral part of the biogas feedstream process.
