Therefore, the regulation of the oxygen vacancy is the key to enhancing the catalytic ability of the catalysts. This paper presents a way to regulate OV in SrMnO₃ during chemical looping oxidative dehydrogenation (CL-ODH) for ethylbenzene by incorporating urea into the conventional citrate process. The creation of oxygen vacancies can be regulated by modifying the quantity of urea introduced, thereby enhancing the oxygen storage capabilities and catalytic efficacy of the catalyst. The optimized catalyst demonstrated effective dehydrogenation activity at 500 °C, but the material became deactivated after the initial 13 redox cycles. This results from the extensive carbonization and degradation of the perovskite catalyst’s structure. The deactivated catalyst was decarbonized in an oxygen environment at 950 °C, while the carbonate was successfully removed, and the perovskite structure was restored. Moreover, the decarbonized catalyst maintained 90% ethylbenzene conversion and 95% styrene selectivity in the redox cycle at 500 °C. This study provides a strategy for modulating oxygen vacancies on oxygen carriers and also offers novel perspectives for designing efficient ODH catalysts, which has significant potential for energy savings in styrene production.</p>","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"64 17","pages":"8722–8734 8722–8734"},"PeriodicalIF":3.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143885638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the stoichiometry of Co extraction from a sulfated acidic aqueous phase containing Co, nickel (Ni), manganese (Mn), and iron (Fe) at low pH levels. Two ionic liquid (IL) combinations were identified as optimal for extraction and selectivity at pH values of 0.85 and 3.28: trioctylmethylammonium benzoate ([Toma][Ba]) dissolved in 1-octyl-3-methylimidazolium bis((trifluoromethyl)sulfonyl)imide ([Omim][Tf₂N]) and trioctylmethylammonium di(2-ethylhexyl)phosphate ([Toma][D2EHP]) in 1-methyl-1-octylpyrrolidinium bis(trifluoromethyl)sulfonyl)imide ([Ompy][Tf₂N]), respectively. The results show improved Co extraction and selectivity at acidic pH levels compared with conventional organic phases, such as D2EHPA/CYANEX 272 dissolved in kerosene. This approach could potentially eliminate the need for Fe precipitation steps prior to solvent extraction.

This study presents the results of gas chromatography–mass spectrometry (GC–MS), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA) of oil and tar obtained from the pyrolysis of pure plastics including high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyethylene (PE), polystyrene (PS), and plastic-biomass mixtures.

FTIR data revealed the presence of various functional groups, including alcohols, aldehydes, ketones, and carboxylic acids, indicating the complexity of the pyrolysis and copyrolysis oil obtained from waste plastics and biomass. TGA data show that tar from all four plastics has a higher decomposition rate, suggesting the presence of heavier hydrocarbons compared with their corresponding oils.
