Abstract: Systems and methods are provided for integrating a fluidized coking process with a catalyst-enhanced coke gasification process. The catalyst for the gasification process can correspond to calcium oxide, a thermally decomposable calcium salt, a potassium salt such as potassium carbonate, or a combination thereof. Examples of suitable calcium salts can include, but are not limited to, calcium hydroxide, calcium nitrate, and calcium carbonate. The calcium oxide, potassium salts, and/or thermally decomposable calcium salts can be introduced into the integrated system, for example, as part of the feed into the coker. It has been unexpectedly discovered that using catalytic gasification as part of an integrated fluidized coking and gasification process can result in an overhead gas stream from the gasifier with increased energy content and/or overhead gas pressure.
