Carbon Dioxide Sequestration from Biogas Production by Microalgae Chlorella sp.

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.

Minimal Time

The air pollution caused by the use of heavy fuel oil in shipping is a growing problem that is drawing increased attention. Methods have been developed to reduce air emissions from ships, more or less aimed at the choice of fuel and the related air emissions. However, the emissions of particulates, sulphur and carbon dioxide, which contribute to the greenhouse effect are not only related to the choice of fuel but also to the amount of fuel consumed in the combustion engines. This paper proposes an additional method that can contribute to the reduction of the air pollution from ships by decreasing the fuel consumption. This is done by specifying the amount of fuel that can be consumed on a specific ocean crossing and by computing a minimal-time route for that given amount of fuel, so decreasing the fuel consumption in a verifiable way.

Methane Carbon

AbstractA vast source of methane is found in gas hydrate deposits, which form naturally dispersed throughout ocean sediments and arctic permafrost. Methane may be obtained from hydrates by exchange with hydrocarbon byproduct carbon dioxide. It is imperative for the development of safe methane extraction and carbon dioxide sequestration to understand how methane and carbon dioxide co-occupy the same hydrate structure. Pair distribution functions (PDFs) provide atomic-scale structural insight into intermolecular interactions in methane and carbon dioxide hydrates. We present experimental neutron PDFs of methane, carbon dioxide and mixed methane-carbon dioxide hydrates at 10 K analyzed with complementing classical molecular dynamics simulations and Reverse Monte Carlo fitting. Mixed hydrate, which forms during the exchange process, is more locally disordered than methane or carbon dioxide hydrates. The behavior of mixed gas species cannot be interpolated from properties of pure compounds, and PDF measurements provide important understanding of how the guest composition impacts overall order in the hydrate structure.
