The catalyst activity is restored by combusting coke attached to the catalyst, which is reacting in the regenerator of the fluid catalytic cracking (FCC) reaction-regeneration system. Then the regenerated catalyst enter the riser reactor for re-utilization. Prior work has assumed that the coke have the formula CHq to burn. The q is the fixed value. However, the value of q will be changed with the...
Considering the problems of catalyst carbon deposition and reforming endothermic reaction in micro reforming chamber, coupled methane catalyst partial oxidation and steam methane reforming can make the micro reforming system auto-supply heat and inhibit the carbon deposited on the catalyst. For the propose of optimizing methane-wet air autothermal reaction conditions, the effect of oxygen to methane...
Some technical problems such as low thermal efficiency, high auxiliary power ratio and severe abrasion of heating surface are existed in the operation of circulating fluidized bed boilers which combust bad fuels generally, these disadvantages restrict the farther expansion of circulating fluidized bed boiler to the power field. Based on the balance of material, energy and carbon content, and on the...
