The invention relates to the field of preparation of materials for cyan chloride (CNCl) prevention, in particular to an ammonia-free system cobalt (Co)-loaded catalyst material for CNCl prevention andpreparation thereof. Coconut shell broken activated carbon is adopted as a carrier skeleton material and loaded with a metallic Co salt of 5 wt%-15 wt%. Water is adopted as a solvent medium, solublesubstances of the metallic Co salt serve as active components, a Co-loaded catalyst prepared through an impregnation method has a certain prevention effect on the CNCl, and meanwhile the problem thatcurrent CNCl preventing carbon adopts ammonium hydroxide as a solvent, and consequently a stimulative ammonia odor overflows in the later using process can be avoided effectively.

Appl.No 2019108515 Applicant Inventor Дорохов Роман Викторович (RU)
FIELD: technological processes. SUBSTANCE: invention relates to methods of producing air regeneration products for human respiratory protection systems against chemical and biological agents. Method of producing a product for air regeneration involves reacting a hydrogen peroxide solution stabilized with magnesium sulphate in molar ratio hydrogen peroxide / magnesium sulphate (H2O2/MgSO4) = 450÷700 and sodium and potassium hydroxides obtained by applying any known method (impregnation, aerosol sputtering, etc.) of the obtained alkaline solution of hydrogen peroxide to an indifferent porous matrix of required geometrical dimensions and subsequent dehydration of the system. Dehydration of the indifferent porous matrix impregnated with the initial alkaline hydrogen peroxide solution is carried out either by drying in a vacuum at temperature of 30÷150 °C, or in a stream of dried decarbonized gas at atmospheric pressure and temperature of 60÷220 °C. In alkaline solution of hydrogen peroxide after addition of magnesium sulphate after 1–3 minutes orthoboric acid is introduced in molar ratio hydrogen peroxide / orthoboric acid (H2O2/H3BO3) = 285÷850, wherein sodium and potassium hydroxides are introduced into the liquid phase simultaneously in two portions with interval of 6–10 minutes such that the temperature in the synthesis zone does not exceed 60 °C. EFFECT: product for air regeneration obtained according to the invention has a higher degree of carbon dioxide treatment and provides a longer time of protective action during its operation in human life support systems. 1 cl, 1 tbl

FIELD: chemistry. SUBSTANCE: invention relates to a filter medium for respiratory protection. Filter medium includes material based on manganese oxide doped with iron, having average pore size (determined by BJH method) in range from 1 to 4 nm and surface area (determined by BET method) making at least 300 m2/g, or at least 350 m2/g, or at least 400 m2/g. Material can be made by a method of redox co-precipitation in an aqueous solution at low temperature or a method of thermal decomposition of oxalates. Filter comprising said material comprises housing having airflow inlet opening and airflow outlet opening, wherein the filter medium is located between the air flow inlet opening and the airflow outlet hole. EFFECT: material has high porosity and surface area for more efficient absorption of hazardous gases. 16 cl, 3 dwg, 5 tbl, 10 ex
