Abstract

In an integrated fluid coking and gasification process wherein a stream of fluidized solids is passed from a fluidized bed coking zone to a second fluidized bed and wherein entrained solid fines are recovered by a wet scrubbing process and wherein the resulting solids-liquid slurry is stripped to remove acidic gases, the stripped vapors of the stripping zone are sent to the gas cleanup stage of the gasification product gas. The improved stripping integration is particularly useful in the combination coal liquefaction process, fluid coking of bottoms of the coal liquefaction zone and gasification of the product coke.

Cryogenic fractionator gas as stripping gas of fines slurry in a coking and gasification process

Patent DeGeorge, Charles W. (Chester, NJ)

In an integrated coking and gasification process wherein a stream of fluidized solids is passed from a fluidized bed coking zone to a second fluidized bed and wherein entrained solid fines are recovered by a scrubbing process and wherein the resulting solids-liquid slurry is stripped with a stripping gas to remove acidic gases, at least a portion of the stripping gas comprises a gas comprising hydrogen, nitrogen and methane separated from the coker products.

Coking and gasification process

Patent Billimoria, Rustom M. (Houston, TX); Tao, Frank F. (Baytown, TX)

An improved coking process for normally solid carbonaceous materials wherein the yield of liquid product from the coker is increased by adding ammonia or an ammonia precursor to the coker. The invention is particularly useful in a process wherein coal liquefaction bottoms are coked to produce both a liquid and a gaseous product. Broadly, ammonia or an ammonia precursor is added to the coker ranging from about 1 to about 60 weight percent based on normally solid carbonaceous material and is preferably added in an amount from about 2 to about 15 weight percent.

Process for treating moisture laden coal fines

Patent Davis, Burl E. (New Kensington, PA); Henry, Raymond M. (Gibsonia, PA); Trivett, Gordon S. (South Surrey, CA); ...

A process is provided for making a free flowing granular product from moisture laden caked coal fines, such as wet cake, by mixing a water immiscible substance, such as oil, with the caked coal, preferably under low shear forces for a period of time sufficient to produce a plurality of free flowing granules. Each granule is preferably comprised of a dry appearing admixture of one or more coal particle, 2-50% by weight water and the water immiscible substance.
