Abstract

Hydration of pure calcium oxide spheres of 36 mm dia. were affected in a carefully designed spray reactor under controlled reaction conditions. The progress of the reaction was followed by recording the temperature profiles as functions of time and radial positions within the reacting solid spheres. The temperature profiles indicate that the reaction occurs in two stages. The first stage corresponds to the reaction with water in the liquid form. The second stage is due to the reaction with water in the vapor form. It was further indicated that at some critical spray condition this violent solid-liquid reaction proceeds virtually isothermally and stops short of completion. A kinetic model is suggested to explain the observed temperature profiles. © 1980.
