The batch process was used for CO2 absorption with solid alkalis, and the recirculation process was used for CO2 desorption with solid acid catalysts. The CO2 equilibrium solubility and pKa were also measured at 293 K with results comparable to the literature. The catalytic tests discovered that the heterogeneous catalysis of tertiary amines on both absorption and desorption sides were quite different from monoethanolamine (MEA) and diethanolamine (DEA). These results were illustrative as a start-up to further study of the kinetics of heterogeneous catalysis of CO2 to tertiary amines based on their special reaction schemes and base-catalyzed hydration mechanism.<\/jats:p>","DOI":"10.3390\/molecules24061009","type":"journal-article","created":{"date-parts":[[2019,3,14]],"date-time":"2019-03-14T04:15:29Z","timestamp":1552536929000},"page":"1009","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Study of Catalytic CO2 Absorption and Desorption with Tertiary Amine DEEA and 1DMA-2P with the Aid of Solid Acid and Solid Alkaline Chemicals"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4333-4118","authenticated-orcid":false,"given":"Huancong","family":"Shi","sequence":"first","affiliation":[{"name":"Department of Environmental Science and Engineering, College of Science, University of Shanghai for Science and Technology, Shanghai 200093, China"},{"name":"Clean Energy Technology Research Innovation (CETRI), Faculty of Engineering and Applied Science, University of Regina, 3737 Wascana Parkway, Regina, SK S4S 0A2, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Environmental Science and Engineering, College of Science, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiming","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Environmental Science and Engineering, College of Science, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linna","family":"Zheng","sequence":"additional","affiliation":[{"name":"Department of Environmental Science and Engineering, College of Science, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lifeng","family":"Cui","sequence":"additional","affiliation":[{"name":"Department of Environmental Science and Engineering, College of Science, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuping","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Environmental Science and Engineering, College of Science, University of Shanghai for Science and Technology, Shanghai 200093, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paitoon","family":"Tontiwachwuthikul","sequence":"additional","affiliation":[{"name":"Clean Energy Technology Research Innovation (CETRI), Faculty of Engineering and Applied Science, University of Regina, 3737 Wascana Parkway, Regina, SK S4S 0A2, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"234","DOI":"10.1016\/j.jclepro.2017.09.285","article-title":"A modeling-optimization framework for assessment of CO2 absorption capacity by novel amine solutions: 1DMA2P, 1DEA2P, DEEA, and DEAB","volume":"171","author":"Afkhamipour","year":"2018","journal-title":"J.
