Understanding the Kinetics of CO 2 Hydrate Formation in Dry Water for Carbon Capture and Storage: X-ray Diffraction and In Situ Raman Studies
National University of Singapore · Indian Institute of Technology Madras
Abstract
Hydrate-based carbon capture and storage (HBCS) is a sustainable and promising approach to combating global warming by utilizing water, which is a ubiquitous resource. Here, we report a comprehensive study of CO2 hydrate formation in dry water (DW), a water-in-air dispersion confined in silica particles, for improving the kinetics of hydrate growth. Utilizing a combination of a home-built high-pressure reactor, in situ Raman spectroscopy, and powder X-ray diffraction (PXRD), we elucidate the crystal structure, growth dynamics, and morphology of CO2 hydrates formed in DW, with and without the kinetic hydrate promoter, l-tryptophan. Our analysis reveals that CO2 forms structure I (sI) hydrate in DW, with hydrate…
