    摘要: A method is provided for controlling the operating temperature of a catalytic reactor using a closed-loop system that provides for varying the reactor input and other operating parameters in order to maintain the operating temperature of the reactor at or near the initial setpoint temperature for operation of the reactor. In one example, maximum and minimum operating temperatures with a catalytic partial oxidation reactor are controlled, as well as maintaining control over the corresponding minimum required ratio of oxygen atoms to carbon atoms, such that the operating temperature within the reactor is maintained below the material limits but above threshold temperatures for coking.

    摘要: A combustion enhancing catalyst is deposited on a particulate refractory substrate such as sand. The solid fuel is contacted with the impregnated substrate and burned, for example, in a fluidized bed combustor. The substrate and catalyst remains in the combustor thereby obviating problems of catalyst loss and adverse effects of emitted metal particles.
