COMPOSITE SORBENT-INDICATOR FOR DESULPHURATION OF FUEL GAS AND METHOD OF USE THEREOF Russian patent published in 2025 - IPC B01J20/04 C01G11/00 G01N31/22 B01D53/48

Abstract RU 2840351 C1

FIELD: chemistry.

SUBSTANCE: invention relates to chemical industry. Disclosed is a sorbent-indicator containing, wt.%: calcium carbonate: 72, cadmium acetate 2-aqueous: 7 and water: 21. Method of producing sorbent-indicator involves successive mixing calcium carbonate, cadmium acetate 2-aqueous and water, packing thick mass in spherical moulds and drying at temperature 105 °C. Also disclosed is use of the sorbent-indicator for trapping and indicating sulphur compounds in gas mixtures.

EFFECT: invention enables to identify sulphur compounds in gas mixtures without using expensive measuring devices.
