Abstract
A reactor system for continuously effecting the hydrolysis of cellulosic materials, as relatively concentrated aqueous mixtures, comprises a tubular reactor, a high solids pump, steam injecting means, a discharge valve controlled by pressure-responsive means, and means for collecting and recovering the reaction products from the hydrolyzate. The high-solids pump apparatus utilizes a valve having a flow distributing passageway of arcuate, uniform circular cross-section. The various portions of the apparatus are constructed with uniform internal dimensions and configurations, so as to avoid any constriction to flow of the material therethrough, thus minimizing the tendency for blockages to occur therewithin. The loading mechanisms are unloaded alternatingly by a reciprocating ram, so as to substantially continuously feed material through the associated valve.
