<p>A method for continuously manufacturing a high-temperature reducing gas, comprising: using a reducing gas manufacturing equipment including a heat medium heating apparatus and a gas reforming apparatus provided below said heat medium heating apparatus; burning a fuel gas in said heat medium heating apparatus to continuously produce a high-temperature combustion exhaust gas; on the other hand, introducing heat medium particles having an average particle size within the range of from 50 to 500 mu m into said heat medium heating apparatus to heat to a prescribed temperature and fluidize said particles through heat exchange with said high-temperature combustion exhaust gas; blowing a gas to be reformed containing CO2 and H2O and a hydrocarbon-containing gas into said gas reforming apparatus, while introducing said heated and fluidized particles from said heat medium heating apparatus into said gas reforming apparatus; thereby heating said gas to be reformed and said hydrocarbon-containing gas, through heat exchange with said heated and fluidized particles, in said gas reforming apparatus to reform by reaction said gas to be reformed and said hydrocarbon-containing gas into a high temperature reducing gas rich in H2 and CO; and then, feeding said fluidized particles cooled through said heat exchange with said gas to be reformed and said hydrocarbon-containing gas back into said heat medium heating apparatus, thereby continuously manufacturing a high-temperature reducing gas while using said fluidized particles in recycle.</p> |
