Carbon dioxide to carbon nanotube scale-up [PDF]
arXiv, 2017 Team C2CNT, or team Carbon dioxide to carbon nanotubes, proprietary technology directly removes the widest range of carbon dioxide from the ecosystem. C2CNT technology simply transforms low to high carbon dioxide into carbon and oxygen, and the carbon produced is permanently removed, that is stable on the order of geologic time frames. C2CNT technology

Energy Science &Engineering, EarlyView.2024 was the hottest year on record and the first in which global temperature and atmospheric CO2 concentration exceeded preindustrial levels by more than 1.5°C and 52%, respectively. In response to these alarming trends, significant efforts were made to advance carbon capture, utilization, and storage technologies throughout the year.

Energy Science &Engineering, EarlyView.ABSTRACT Acid gases, containing CO2 and H2S, are by‐products of gas sweetening. Geological sequestration of these gases in naturally fractured reservoirs (NFRs) is a practical method to reduce greenhouse gas emission. An industrially accepted approach to simulate fluid flow in NFRs is the dual‐porosity method; however, this method needs multiple ...

Energy Science &Engineering, EarlyView.Schematic approach of the green diesel production process and its utilization. ABSTRACT A unique green catalyst was derived from novel powdered Uzere tallow seeds shell calcined at 700°C for 1 h in a muffle furnace. The catalytic activity of the Uzere acidified catalyst was due to a high proportion of sulphur trioxide, calcium oxide, and potassium ...

The stability of stratified horizontal flows of carbon dioxide at supercritical pressures [PDF]
arXivFluids at supercritical pressures exhibit large variations in density near the pseudo critical line, such that buoyancy plays a crucial role in their fluid dynamics. Here, we experimentally investigate heat transfer and turbulence in horizontal hydrodynamically developed channel flows of carbon dioxide at 88.5 bar and 32.6{\deg}C, heated at either the ...

Sensitivity of three-dimensional boundary-layer stability to intrinsic uncertainties of fluid properties: a study on supercritical CO2 [PDF]
The intrinsic uncertainty of fluid properties, including the equation of state, viscosity, and thermal conductivity, on boundary layer stability has scarcely been addressed. When a fluid is operating in the vicinity of the Widom line (defined as the maximum of isobaric specific heat) in supercritical state, its properties exhibit highly non-ideal ...
