The carbon bubble is a hypothesized bubble in the valuation of companies dependent on fossil-fuel -based energy production, resulting from future decreases in value of fossil fuel reserves as they become unusable in order to meet carbon budgets and recognition of negative externalities of carbon fuels which are not yet taken into account in a co...

2022年12月25日 · Carbon dioxide (CO2) bubbles are common during carbon capture, utilization, and storage (CCUS) processes and have many impacts on water conservancy machinery, metallurgy, and the chemical industry....

The carbon bubble, also called CO2 bubble, is a theory that has its origin in climate and economic research. The term describes a possible overrating of companies that could only maintain their growth forecasts for the next few years by consuming fossil fuels on a scale that would violate the two-degree limit of the Copenhagen Treaty.

2020年8月5日 · In this work, a kind of hydrophobically modified water-soluble polyelectrolyte (HMPE) was used in the stabilization of CO 2 foam containing millimeter-sized and micron-sized bubbles, which both exhibit high stability and perfect foam viscoelasticity, due to the enhancement of the mechanical strength of the foam films through HMPE absorbed at the...

2023年12月20日 · Stability and dynamics of a bubble comprising carbon dioxide and air have been theoretically investigated. The stability was formulated using thermodynamic inequalities and potential energies. The dynamics were studied by numerically solving the time evolution equation for the bubble radius.

2024年6月7日 · The dissolution process of CO2 bubbles adhered to a flat plate in a rectangular channel at different flow velocities is studied experimentally and theoretically

2015年4月17日 · We conducted quantitative textural analysis of vesicles in high temperature and pressure carbonate assimilation experiments (1200 °C, 0.5 GPa) to investigate CO 2 generation and subsequent bubble migration from carbonate into magma.

2019年6月1日 · Industrial applications of Ionic liquids (ILs) in CO 2 capture are still limited due to lack of research on CO 2 -ILs bubble dynamics. A CFD model was developed to understand CO 2 bubble formation in the pool of ILs by coupling improved VOF (Volume of Fluid) method with FW–H (Ffowcs Williams and Hawkings) acoustic formulation.

2016年5月3日 · Carbon dioxide (CO 2) gas is a major carbon source for microalgal cultivation. It is usually sparged into photobioreactors in the form of bubbles. The behaviour of the bubbles significantly affects mass transfer, distribution and microalgae growth.

2023年9月28日 · CO 2 capture experiments were carried out in a small-scale bubble column reactor using alkaline solutions of sodium hydroxide. The results of the experiments show that a higher NaOH content in the liquid phase and elevated CO 2 concentrations in the gas mixture led to a higher CO 2 removal efficiency.
