This study introduces an Integrated Carbon Capture and Utilisation-Reverse Water Gas Shift (ICCU-RWGS) approach, a novel method for in situ CO2 adsorption conversion, leveraging the synergistic effects of CaO within NaCl-CaCl2 molten salt blend to enhance capture conversion efficiency. Building upon this foundation, we optimize concentration operating temperature maximize uptake performance. The research focuses on integrating with (mass ratio 4:6) improve sorption Findings show significant enhancements CO yield presence compared systems without it. optimal are identified maximum yield. Characterisation techniques like in-situ infrared spectroscopy, XRD, SEM provide insights into behavior salt, revealing solubility partial carbonate formed from CaO, dispersion particles, their morphological characteristics. Overall, demonstrates potential CaO-molten integration improving ICCU-RWGS process efficiency contributes development more effective sustainable ICCU technologies.

Enhanced Thermal Performance of Binary Eutectic Chloride Salt by Integrating Nanoparticles: A Molecular Dynamics Study

Опубликована: Янв. 1, 2025

Chloride salts are considered the most promising high-temperature thermal energy storage media for next-generation concentrating solar power (CSP) plants. To enhance performance of NaCl-KCl eutectic salt phase change material (PCM), composite materials (CPCMs) were developed by separately integrating Al2O3, CuO, and SiO2 with PCM. The microstructure evolution thermophysical properties systems investigated means molecular dynamics (MD) simulations. effects different nanoparticles on PCM systematically compared, mechanism desirable enhancement was elucidated from a microscopic perspective. Nanoparticle doping effectively improved heat transfer Specifically, CuO exhibited significant effect conductivity PCM, maximum increase 28.1%. specific capacity raised 9.2% 7.4% addition Al2O3 nanoparticles, respectively. However, introduction inevitably viscosity, having comparatively smaller effect, increasing viscosity only 14.2% at higher temperatures. Based analysis, attributed to in average potential atoms system, which strengthened interatomic interactions. This study is expected provide valuable guidance design application molten based materials.
