The effective capturing of carbon dioxide using regenerable high capacity sorbents is a prerequisite for industrial applications aiming at CO 2 capture and sequestration. The removal of CO 2 directly from chemical reaction environments at high temperature is a less energy intensive method of its separation with the added benefit of improved efficiency in equilibrium limited reactions.

Carbon Capture - an overview | ScienceDirect Topics

Carbon capture, utilization, and storage (CCUS) is an important process for reducing atmospheric CO2 emissions, especially from power plants and other point resources [1]. Industries like coal-fired power plants and oil refineries contribute to about 25%–30% of total CO 2 emissions to the atmosphere [2–5]. The flue gases from these sources ...

Cyanopropylsilyl-bonded phase material was the selected stationary phase. The separation method was applied to real samples of SEOM (2.6, 5.6 and 8.5 mg) spiked with n-alkanes, PAH and oxy-PAH. n-Alkanes overlapped with PAH due to an excess of n-alkanes in real samples overloading the capacity of the stationary phase.
