If the plant comprises a pre-treatment section, upstream the e-SMR reactor, co-reactant feeds can be added at different places in the pre-treatment section, e.g. hydrogen can be added upstream an hydrodesulfurization to facilitate hydrogenation reactions, and/or steam can be added upstream a prereformer to facilitate reforming reactions, and/or CO2 can be added to a gas conditioning unit to partly shift the feed gas according to the water-gas shift reaction.
