Hydrogen recovery from hydrocarbons involves steam reforming in presence of catalyst, separating hydrogen and recycling residual gas stream to reformer

摘要

Recovery of hydrogen from hydrocarbons by steam reforming involves converting the hydrocarbons with steam to an H2-rich synthesis gas in the presence of a catalyst. This gas is separated into an H2 stream and a residual gas stream, which is then (partly) recycled to the conversion stage.
