METHOD OF PRODUCING CARBON DIOXIDE CHEMISORBENT Russian patent published in 2015 - IPC B01J20/04 B01J20/30 

FIELD: chemistry.

SUBSTANCE: invention relates to production of a sorbent for equipment for protecting respiratory organs. The method of producing a sorbent includes mixing powdered calcium hydroxide or oxide with water with weight ratio Ca²⁺/H₂O of (0.70.3)/1 and adding a calculated amount of potassium orthophosphate having density of 1.41±0.05 g/cm³. The orthophosphate solution is prepared with molar ratio KOH/K₂HPO₄, of (0.9-1.1)/1, or molar ratio KOH/KH₂PO₄ of (1.9-2.1)/1. The obtained mixture is stirred, held and moulded. The granules are dried to residual moisture content of 16-21 wt %.

EFFECT: invention enables to obtain a sorbent having a high chemisorption rate, high dynamic capacity for carbon dioxide and mechanical strength.
