The invention relates to a process and a plant for producing pure hydrogen from an input gas containing hydrogen and hydrocarbons, in particular from a hydrogen-containing refinery off-gas, by steam reforming in a steam reforming stage and multi-stage hydrogen enrichment. According to the invention the input gas containing hydrogen and hydrocarbons is separated in a first hydrogen enrichment stage into a hydrogen-enriched substream and a hydrogen-depleted sub stream, wherein at least a portion of the hydrogen-enriched substream is supplied to a second hydrogen enrichment stage or introduced into the pure hydrogen product stream and at least a portion of the hydrogen-depleted substream is supplied to the steam reforming stage as a reforming feed stream or as part thereof and/or to the burners as a fuel gas stream.

Methods and systems are disclosed for using industrial waste for the production of hydrogen gas. The method includes examining a ph level of the industrial waste, removing contaminate from the industrial waste, conditioning and concentrating the industrial waste to a proton-rich solution, and using the resulting proton-rich solution as the proton source in a hydrogenase catalyzed hydrogen production system.

The present invention provides a process for preparing higher-value products from carbonaceous feedstocks. The process includes converting carbonaceous feedstock in a hydromethanation reactor to a methane-enriched raw product stream, converting the methane-enriched raw product stream to a methanol synthesis feed gas, then converting the methanol synthesis feed gas to higher-value products such as methanol and dimethyl ether.
