Abstract

A technology has been developed for producing an absorber of sulfur compounds from activated zinc oxide of local production and magnesium oxide. A carbamide solution was used as a plasticizer, which extends the setting time of the mass of the absorber. The activation of the muffle zinc oxide was carried out with an ammonia-carbonate solution. Active zinc oxide is also obtained from spent zinc scavengers. The main production parameters of zinc oxide absorbers formed in a screw extruder and a tablet machine are determined. The intensity of the extrudates depends on the activation method and varies from 22.5 to 29%.
