TWO papers by Associate Professor Praveen Linga, published in 2013 and 2016, have been listed as a “Top 25 most cited paper” in Energy and Applied Energy Journals as of 23 January 2018, respectively. This constitutes the Top 25 most cited (top 1%) of more than 6,000 publications in the Journal since 2013.
The first paper published in Energy, titled “Pre-combustion capture of carbon dioxide in a fixed bed reactor using the clathrate hydrate process” (Volume 50, pp. 364-373), has 120 citations and is the 9th most cited paper within the Journal with a field weighted citation impact (FWCI) of 10.49 (from Scopus as of 23-Jan-2018). This paper has received this recognition for two consecutive years.
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 a simulated fuel gas mixture employing the clathrate hydrate process in a fixed bed configuration.
The results showed that inter-particle pore space is important and plays a vital role in enhancing the hydrate formation kinetics. The 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 the enhanced kinetics of hydrate formation in the sand in a laboratory setting spurred detailed investigations to further design and evaluate cheaper/lightweight materials for applying the hydrate technology for CO2 capture.”
The second paper published in Applied Energy, titled “Review of natural gas hydrates as an energy resource: Prospects and challenges” (Volume 107, pages 1633-1652), was co-authored by Mr. Zheng Rong Chong, Mr. She Hern Bryan Yang, Dr. Ponnivalavan Babu and supervised by Assoc Prof Linga, Department of Chemical & Biomolecular Engineering in collaboration with Professor Xiaosen Li of the Key Laboratory of Gas Hydrate, Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences, China. The review paper presented a comprehensive account of the state of the art developments on natural gas hydrates as an energy resource, prospects and challenges in developing technologies to recover energy from this vast resource. The paper has been cited 141 times and has a FWCI of 28.53 (from the Scopus database as of 23-Jan-2018), and was the top ranked publication among 1600+ articles published in the journal in 2016.
