COMBUSTION DEVICE THAT PRODUCES HYDROGEN WITH RE-USE OF CAPTURED CO2

摘要

The invention relates to a combustion device which produces fumes containing CO₂ and steam and which consists of: a circulating fluidised bed reaction chamber (1, 2), a separator (10, 20), and heat recuperator means comprising one part which is disposed in a dense fluidised bed (12, 12a, 22). The inventive device is characterised in that the part of the heat recuperator means that is disposed in the bed comprises catalyst tubes (120, 120a, 220) through which a gas mixture flows. The aforementioned gas mixture comprises natural gas and/or naphtha or refinery gas or two or more of said gases. The gas is reformed and transformed into synthesis gas containing hydrogen. Since the catalyst tubes are disposed in the dense fluidised bed formed by the ash from the combustion, the catalyst can be heated uniformly and the natural gas mixture reforming reaction can be promoted.
