ABSTRACT:

Research objectives were to: study liquid and gas phase flow patterns in a bubble column reactor by comparing observations made with reported observations and hydrodynamic models; study mixing of two miscible liquid solutions with and without solid suspension in a bubble column reactor; study the kinetics of dissolution of a reactive solid phase suspended in the liquid phase in a bubble column reactor; and calculate mass transfer coefficients and apparent reaction rate from suitable mathematical models.  Observations and conclusions are summarized in a series of viewgraphs.
