Abstract:
A method of estimating the effluent amount for each component of an effluent at the outlet of a reaction vessel in which a liquefying reaction is carried out by blowing a hydrogen gas into a coal slurry, comprising the steps of:calculating the reaction vessel residence time within the reaction vessel for each of a gaseous phase and a liquid phase resulting from said liquefying reaction by assuming the effluent amount for each component of the effluent; calculating the effluent amount for each component of the effluent on the basis of the reaction vessel residence time, the inflow amount for each component of the influent into the reactor, and a primary irreversible reaction rate formula derived from a coal liquefying reaction model; and repeating the calculations until the assumed effluent amount for each component coincides, within a range of error, with the effluent amount for each component obtained by calculation so as to determine the estimated value of the effluent amount for each component.
