METHOD OF CALCULATING FOR PRODUCTS OF COAL LIQUEFACTION REACTION

WIPO Patent Application WO/1999/050373

A1

A method for estimating the amount of each component of the effluent from a coal liquefaction reactor system composed of vessel-type reactors (16a, 16b, 16c). First, a presumption is taken for the amount of each component of the effluent and a gas-liquid equilibrium of an effluent mixture having the presumed composition in the reactor system. Rates of volumetric flow are then calculated for a gas phase and liquid phase and retention times in the reactor system for a gas phase and a liquid phase ($g(t)1G,$g(t)2G,$g(t)3G) ($g(t)1S,$g(t)2S,$g(t)3S) are calculated. The amount of each component in the effluent is calculated from the retention times thus obtained ($g(t)1, $g(t) ... $g(t)n), the amount of each component flowing into the reactor system and a linear irreversible reaction rate equation. The amount of each component in the effluent obtained from the calculation is compared to the presumption mentioned above. Such a series of calculation is repeated until a resultant calculated composition becomes consistent with a presumed composition within a predetermined range of an error.
