Abstract
In a coal-gasification reactor installation, carbon dioxide gas is added into a liquid coal suspension in the form of fine bubbles of gas to improve the flowability and dispersion of the liquid coal suspension. In a preferred embodiment, carbon dioxide is separated from the gaseous reactor products, dissolved in an ammonium solution, reacted to form solid ammonium carbonate salt; the solid chemical salt is added to the liquid coal suspension where it is made to decompose and generate carbon dioxide gas.
