Catalytic Reforming Process and Equipment to Maximize the Utilization of the Sensible Heat Recovered from High-Temperature Molten Slag

摘要

The present invention relates to a methane stream to which methane is supplied as a reaction raw material; And, as a reforming agent thermal energy for CO ₂ stream and the steam is supplied H ₂ O stream is steam Chemistry vapor stream from at least one reactant stream containing the modified agent stream, and temperature was raised, and reaction of the reactants CO ₂ is supplied A sensible heat recovery stream supplied with the oxygen-containing gas recovered from the sensible heat of the molten slag, and a flue gas stream exhausted from the flue gas generated by the combustion reaction of the combustible fuel gas and oxygen A reforming reactor in which the reactant stream is supplied, the reactant passes through a reactor equipped with a catalyst, and the reactant reacts to generate a high-temperature reducing gas containing CO and H ₂ ; A burner system which is supplied with the fuel stream and the sensible heat recovery stream to indirectly heat the reforming reactor by combustion heat generated by a combustion reaction between the fuel and oxygen to supply reforming reaction energy; A heat exchanger for preheating the reactant stream from the exhaust gas stream to preheat the reactant stream and supplying the reactant stream to the reforming reactor; And a heat exchanger for preheating an oxygen-containing gas for heat-exchanging the sensible heat recovery stream from the exhaust gas stream and supplying the heat to the burner system.
