Plasma technology reaches rapidly increasing efficiency in catalytic applications. One such application is the splitting reaction of CO2 to oxygen and carbon monoxide. This could be a cornerstone power-to-X processes that utilize electricity produce value-added compounds as chemicals fuels. However, it poses problems practice due its highly endothermal nature challenging selectivity. In this co...

The Paris Agreement’s temperature goals require global CO2 emissions to halve by 2030 and reach net zero 2050. capture utilization (CCU) technologies are considered promising achieve the goals. This paper investigates which CCU technologies—using atmospheric, biogenic, or fossil CO2—are compatible, based on life cycle technological maturity criteria. We systematically gathered harmonized techno...

Supercritical CO2 (ScCO2) emulsion has attracted lots of attention, which could benefit both climate control via storage and industry revenue through significantly increased oil recovery simultaneously. Historically, aqueous soluble surfactants have been widely used as stabilizers, though they suffer from slow propagation, relatively high surfactant adsorption well injectivity issues. In contra...

In order to produce microalgal lipids that can be transformed to biodiesel fuel, effects of concentration of CO(2) aeration on the biomass production and lipid accumulation of Nannochloropsis oculata in a semicontinuous culture were investigated in this study. Lipid content of N. oculata cells at different growth phases was also explored. The results showed that the lipid accumulation from loga...

This paper presents the results from using a physical absorption process to absorb gaseous CO2 mixed with N2 using water by producing tiny bubbles via a liquid-film-forming device (LFFD) that improves the solubility of CO2 in water. The influence of various parameters-pressure, initial CO2 concentration, gas-to-liquid ratios, and temperature-on the CO2 removal efficiency and its absorption rate...

The purpose of this study was to examine the effects on humans of exposure to carbon dioxide (CO2 ) and bioeffluents. In three of the five exposures, the outdoor air supply rate was high enough to remove bioeffluents, resulting in a CO2 level of 500 ppm. Chemically pure CO2 was added to this reference condition to create exposure conditions with CO2 at 1000 or 3000 ppm. In two further condition...
