A PAPER by Associate Professor Praveen Linga, published in 2013, has been listed as a “Top 25 most cited paper” in Energy Journal as of 11 January 2017. This constitutes the Top 25 most cited (top 1%) of more than 6,000 publications in the Elsevier’s Energy Journal published since 2012.
The paper, titled “Precombustion capture of carbon dioxide in a fixed bed reactor using the clathrate hydrate process” (Volume 50, pp. 364-373), has 105 citations and is the 12th most cited paper within the Journal.
Related to gas hydrate formation pertaining to carbon capture, this paper evaluated the performance of two porous materials, silica sand (inter-particle) and silica gel (intra-particle), on carbon dioxide capture from simulated fuel gas mixture employing the clathrate hydrate process in a fixed bed configuration.
The results show that inter-particle pore space is important and plays a vital role for enhancing the hydrate formation kinetics. This work paved the way for the development and testing of new materials with good inter-particle pore space connectivity for the hydrate based gas separation process (HBGS) for carbon dioxide (CO2) capture in the literature.
Said Assoc Prof Linga, “Silica sand is a naturally available material that has allowed the formation of natural gas hydrates for millions of years in marine sediments and permafrost regions. The observed ability of enhanced kinetics of hydrate formation in sand in a laboratory setting spurred detailed investigations to further design and evaluate cheaper/lightweight materials for applying the hydrate technology for CO2 capture.”
