    摘要： An asphalt-containing mineral oil can be deasphalted at temperatures above about 80.degree. C. with methanol serving as the deasphalting solvent. Two liquid phases are produced, an asphalt-rich phase and a methanol-rich phase. By cooling the methanol-rich phase to a temperature below 80.degree. C., two additional liquid phases are produced, an oil-rich phase and a methanol-rich phase.

    摘要： A fixed-sulfur, solid fuel product is obtained by an improved coking process wherein petroleum fractions are coked in the presence of added alkaline earth metal oxides. The fixed-sulfur, solid fuel product comprises coke and from about 3 to 30 weight percent, preferably from about 5 to 15 weight percent, "ash" (calculated as calcium oxide) derived from the alkaline earth additive. The quantity alkaline earth metal oxide or precursor thereof added to the coking zone is dependent on the sulfur content of the product coke and on the desired ash content of the solid fuel product. The coking zone may comprise delayed, fluid bed, or moving bed cokers.

    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.
