Nuclei images analysis - technology, diagnostic features and experimental study.

The disclosed continuously operated apparatus (10) is suitable for a variety of chemical processes, including enzymatic conversion of substrates to, for example, organic liquids such as alkanols. In this apparatus (10): A generally vertically disposed fermentation tower (11) defines a generally vertically extending space containing a plurality of vertically arranged, tray-like zones (15a-15h) for the temporary retention, continuous receiving, and continuous gravity discharge of a feedstock. A typical zone, e.g. zone (15c) has a generally horizontal floor (65c) having a drain opening (165c) for the continuous discharge by gravity of partially converted feedstock to the next lower zone (15d). Each zone (e.g. 15c) is further divided into continuously movable segments by movable partitions (157c) for advancing the fermentable feedstock in said fermentation zone toward the drain opening. A collection means (23) disposed beneath the drain opening (165c) continuously collects a portion of the partially converted feedstock and recirculates it through a recirculation system (20) to the uppermost zone (15a). A withdrawing means (41), communicating with the lower end of the tower (11) continuously withdraws the products of the enzymatic conversion process.
