Research from National Taiwan University Yields New Findings on Chemical Engineering

摘要

"The kinetics of the reaction of dense CaO particles (2.5 mm dia)with sulfur dioxide was:studied using a thermogravimetric technique under the conditions of 750-950 degrees C, 1000-5000 ppm SO2, and 6 h reaction time The growth of CaSO4 product layer was observed using a scanning electron microscope. The effect Of internal structural change due to reaction, which complicates the kinetic analysis of porous particles, was eliminated in the present CaSO4," scientists writing in the journal Industrial & Engineering Chemistry Research report.
