One of the principal reactions occurring in the kraft recovery process is the reduction of sodium sulfate to sodium sulfide with a reducing agent. Carbon monoxide is one reducing agent present in the furnace. The purpose of this project was to study the reaction Na/sub 2/SO/sub 4/ + 4CO ..-->.. Na/sub 2/S + 4CO/sub 2/. Basic kinetic data were obtained under various experimental conditions including different sulfate concentrations, carbon monoxide partial pressures, and temperatures. Based on these kinetic data, sulfate reduction was found to be described by a simplified rate equation for the temperature range 1200-1311/sup 0/K which this paper derives, discusses, and then applies toward an energy-efficient mathematical representation of the kraft process.
