In this study, tannin extract (TE) absorption combined with binuclear sulfonated phthalocyanine cobalt organic polymer (OTS) and binuclear sulfonated phthalocyanine cobalt (PDS) with a fixed bed reactor is used for removal of H2S. The effect of gas flow rate, concentration of H2S, co-existence of organic sulfide compounds and O2 were investigated. Then, the effect of total alkalinity content of TE, NaVO3, OTS and PDS was studied in detail. The experimental results demonstrated that 100% H2S conversion could maintain for 13 h at a total alkalinity of 5.0 g\/L, TE concentration of 4.0 g\/L, NaVO3 concentration of 5 g\/L, and OTS and PDS concentration of 0.2 g\/L and 0.2 g\/L, respectively. The OTS and PDS showed synergistic effect on boosting TE desulfurization efficiency. The results provide a new route for the investigation of liquid catalyzed oxidation desulfurization in an efficient and low-cost way.<\/jats:p>","DOI":"10.3390\/ma16062343","type":"journal-article","created":{"date-parts":[[2023,3,15]],"date-time":"2023-03-15T04:39:45Z","timestamp":1678855185000},"page":"2343","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Enhanced Desulfurization by Tannin Extract Absorption Assisted by Binuclear Sulfonated Phthalocyanine Cobalt Polymer: Performance and Mechanism"],"prefix":"10.3390","volume":"16","author":[{"given":"Bing","family":"Wang","sequence":"first","affiliation":[{"name":"Faculty of Environmental Science and Engineering, Kunming University of Science and Technology, Kunming 650500, China"},{"name":"Hunan Research Institute of Nonferrous Metals, Changsha 410100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huanyu","family":"Chen","sequence":"additional","affiliation":[{"name":"Hunan Research Institute of Nonferrous Metals, Changsha 410100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xingguang","family":"Hao","sequence":"additional","affiliation":[{"name":"Faculty of Environmental Science and Engineering, Kunming University of Science and Technology, Kunming 650500, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai","family":"Li","sequence":"additional","affiliation":[{"name":"Faculty of Environmental Science and Engineering, Kunming University of Science and Technology, Kunming 650500, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Sun","sequence":"additional","affiliation":[{"name":"Faculty of Environmental Science and Engineering, Kunming University of Science and Technology, Kunming 650500, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuan","family":"Li","sequence":"additional","affiliation":[{"name":"Faculty of Environmental Science and Engineering, Kunming University of Science and Technology, Kunming 650500, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ping","family":"Ning","sequence":"additional","affiliation":[{"name":"Faculty of Environmental Science and Engineering, Kunming University of Science and Technology, Kunming 650500, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Dong, Q., Wang, C., and Peng, S.
