GRANULATED SORBENT PRODUCING METHOD Russian patent published in 2016 - IPC B01J20/08 B01J20/04 B01J20/06 B01J20/30

Abstract RU 2578691 C1

FIELD: chemistry.

SUBSTANCE: invention relates to preparation of sorbents used for polishing process and waste gases. Production process includes mixing of aluminium hydroxide, caustic limestone and basic zinc carbonate at a molar ratio of Al₂O₃:CaO:ZnO = 1: (0.5÷2):(0.5÷2) using ultrasonic device, plastification of mixture with water, molding and drying of pellets at a temperature of 110÷120 °C.

EFFECT: invention allows to increase degree of absorption of fluorine and chlorine from gases produced by sorbent.
