Carbon Dioxide Sequestration from Biogas Production by Microalgae Chlorella sp.

Abstract:

In this study, the research team aimed to apply the use of biological capturing system of single cell algae, common microalgae species Chlorella sp. that have higher photosynthetic efficiencies in efficient capturing carbon dioxide. Here, , In the biological CO₂ capturing process, biogas was pumped to the water recycling culturing medium, only CO₂, not CH₄, could dissolved efficiently with the sprayer and recycling medium system. The results showed the microorganisms could resist to methane except H₂S and significantly induced at least 90-95% CO₂ removal efficiency and increased in Cholerella sp. biomass production within 7 day cultivation compared the system without CO₂ feeding (0.6 and 0.4 percentage (g/mL), respectively. Since the biological treatment approach was durable and could possibly further applied for treating flue carbon dioxide exhausted by power plant and fuel-types, and mitigating acid rain, heavy fuel oil, natural gas prevention.
