The results indicated that the removal performance of the SSA\/MCM-41 for cumene was significantly influenced by the process conditions such as bed temperature, inlet concentration, bed height, and flow rate. The dose\u2013response model could perfectly describe the collected breakthrough adsorption data. The SSA\/MCM-41 adsorbent exhibited a reactive temperature region of 120\u2013170 \u00b0C, in which the cumene removal ratios (Xc) were greater than 97%. Rising the bed height or reducing the flow rate enhanced the theoretical adsorption performance metrics, such as theoretical breakthrough time (tB,th) and theoretical breakthrough adsorption capacity (QB,th), whereas increasing the inlet concentration resulted in tB,th shortening and QB,th rising. As demonstrated in this paper, the highest tB,th and QB,th were 69.60 min and 324.50 mg g\u22121, respectively. Meanwhile, the spent SSA\/MCM-41 could be desorbed and regenerated for cyclic reuse. Moreover, two recoverable adsorbed products, 4-isopropylbenzenesulfonic acid and 4, 4\u2032-sulfonyl bis(isopropyl-benzene), were successfully separated and identified using FTIR and 1H\/13C NMR characterization. Accordingly, the relevance of a reactive adsorption mechanism was confirmed. This study suggests that the SSA\/MCM-41 has remarkable potential for application as an adsorbent for the resource treatment of cumene pollutants.<\/jats:p>","DOI":"10.3390\/molecules27165129","type":"journal-article","created":{"date-parts":[[2022,8,11]],"date-time":"2022-08-11T21:15:05Z","timestamp":1660252505000},"page":"5129","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Reactive Adsorption Performance and Behavior of Gaseous Cumene on MCM-41 Supported Sulfuric Acid"],"prefix":"10.3390","volume":"27","author":[{"given":"Dandan","family":"Zhao","sequence":"first","affiliation":[{"name":"Hebei Key Laboratory of Inorganic Nano-Materials, College of Chemistry and Material Sciences, Hebei Normal University, Shijiazhuang 050024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuheng","family":"Liu","sequence":"additional","affiliation":[{"name":"Hebei Key Laboratory of Innovative Drug Research and Evaluation, College of Pharmaceutical Sciences, Hebei Medical University, Shijiazhuang 050017, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaolong","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Hebei University of Science and Technology, Shijiazhuang 050018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinjin","family":"Qian","sequence":"additional","affiliation":[{"name":"Hebei Key Laboratory of Inorganic Nano-Materials, College of Chemistry and Material Sciences, Hebei Normal University, Shijiazhuang 050024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7998-1088","authenticated-orcid":false,"given":"Zichuan","family":"Ma","sequence":"additional","affiliation":[{"name":"Hebei Key Laboratory of Inorganic Nano-Materials, College of Chemistry and Material Sciences, Hebei Normal University, Shijiazhuang 050024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4471","DOI":"10.1021\/acs.chemrev.8b00408","article-title":"Recent advances in the catalytic oxidation of volatile organic compounds: A review based on pollutant sorts and sources","volume":"119","author":"He","year":"2019","journal-title":"Chem.
