METHOD FOR UTILIZATION OF CARBON DIOXIDE USING MICROALGAE CHLORELLA Russian patent published in 2023 - IPC B01D53/62 B01D53/84 

FIELD: bioengineering.

SUBSTANCE: methods for biological purification of exhaust gases from power plants. The method allows to utilize CO₂ bymicroalgae Chlorella kessleri. The method includes the following steps: supplying CO₂ to a photobioreactor-biofilter containing Chlorella kessleri microalgae; photosynthesis, during which the absorption of CO₂ by the cells of the microalgae Chlorella kessleri occurs, then the biomass of the microalgae Chlorella kessleri is obtained. An air mixture or exhaust gases are supplied from power plants with a high content of CO₂ in the range of 15-39%. The photosynthesis stage is carried out in a temperature condition of 25-30°C. Illumination is set in the range from 2500 to 3000 lux.

EFFECT: absorption of gas emissions with high content of CO₂ in the range of 15-39% by Chlorella kessleri microalgae by means of directional cultivation, which is carried out in a matched mode.
