PROCESS FOR PRODUCING HYDROGEN WITH ELECTRICALLY HEATED STEAM METHANE REFORMING

The invention relates to a process for producing hydrogen, comprising a steam methane reforming (SMR) step for producing synthesis gas, in which heat for the endothermic reaction is at least partially provided by converting electrical energy into heat. The synthesis gas is subject to a water-gas shift step and the shift product is subject to a chemical scrubbing step, to afford a carbon dioxide product stream and a hydrogen raw product stream. The hydrogen raw product stream is further purified by means of a hydrogen production step, which affords pure hydrogen and an off-gas stream. The off-gas stream, rich in carbon monoxide and methane, is recycled to the hydrocarbon containing feedstock stream, so that a combined stream of hydrocarbon containing feedstock, off-gas and steam is supplied to the steam methane reforming (SMR) step.
