Abstract:
1. A process for the production of a synthesis gas (B) by steam reforming a hydrocarbon feedstock (A) in a steam reforming reactor, called reactor-exchanger (R 1 ), and for the co-production of electrical energy, in which the input of calories required for steam reforming is obtained by in situ combustion inside the reactor-exchanger (R 1 ) of a first flux of hydrogen ( 5 ) with a flux of air ( 1 ), the flux of hydrogen ( 5 ) coming from steam reforming reactor-exchanger effluents (B) after separation of any CO2 and H2O contained in said effluents (B), said flux of air ( 1 ) necessary for said in-situ combustion being compressed to a pressure of between 0.4 to 4 MPa absolute by a compressor (C 1 ), and wherein effluent of combustion ( 6 ) that results from said combustion is divided into at least two portions: a first portion ( a second portion (
