Experimental investigation of reactive granulation of sodium carbonate with dodecyl-benzenesulfonic acid
Original language description
Qualitative understanding and quantitative description of the elementary processes (i.e. binder spreading on primary particles, binder solidification due to chemical reaction) is an important perquisite for control and design of reactive granulation. Thekinetics of the reactive wetting of a static sodium carbonate pellet by a macroscopic dodecyl-benzenesulfonate acid droplet was recently investigated. Parameters characterizing substrate wetting (asymptotic contact angle and spreading rate constant) andchemical reaction kinetics (effective diffusion coefficients and reaction rate constants) were determined as a function of temperature. In the following work is considered reactive granulation in a mechanically agitated powder bed. A reaction kinetic model of dry neutralization was formulated and its parameters (asymptotic molar quantity of evolved CO2, reaction rate constant combined with wetted surface and induction time) were estimated.
