Ultraviolet photoelectron spectroscopy (UPS) results and Density Functional Theory (DFT) calculations suggested that Mott-Schottky heterostructures were constructed in CoNi@NC and FeCoNi@NC, leading to the spontaneous electron transfer from alloy cores with smaller work functions to NC shells. DFT calculations also confirm that the number of electrons transfer from alloy cores to NC shells with 1.46 a.u. and 1.59 a.u. for CoNi@NC and FeCoNi@NC, respectively. The increased electron density on NC shells improved the absorption strength of reactants and the intermediate, thereby reducing the energy barriers for the dehydrogenation of FA and hydrodeoxygenation of guaiacol. FeCoNi@NC, due to its higher surface electron density, exhibited better catalytic activity than that of CoNi@NC, 93.4% conversion of guaiacol and 87.3% selectivity to phenol can be achieved at 260 °C within 12 h, which is even better than commercially available Pd/C catalyst. The mechanistic studies revealed that guaiacol is first converted into catechol via the demethylation and hydrolysis, then to phenol via hydrogenolysis over FeCoNi@NC with the aid of FA. Moreover, the magnetically separatable FeCoNi@NC possessed high catalytic stability because NC shells protect alloy cores from the acidic solution.</p></div>","PeriodicalId":326,"journal":{"name":"Fuel Processing Technology","volume":"254 ","pages":"Article 108045"},"PeriodicalIF":7.5,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0378382024000158/pdfft?md5=36e0f9a97d35333e9bafdad11484da43&pid=1-s2.0-S0378382024000158-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139503950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the findings in this area relates to the halogen removal, where high efficiencies can be achieved already in the pyrolysis process. In contrast, the removal of other heteroatoms has mainly been studied in the liquid product, usually in a hydrogen atmosphere and in the presence of a catalyst. It seems economically feasible to remove the heteroatoms as early as possible in the recycling process. This can be achieved in part by washing the waste plastic in water, which can remove a large proportion of the heteroatoms present as impurities.

{"title":"Efficient and stable Fe-Ce-Al catalyst for catalytic deoxygenation of lignin for phenol and hydrocarbon-rich fuel: Effect of the synthesis method","authors":"Yifei Chen ,&nbsp;Hongyuan Wang ,&nbsp;Jida Wang ,&nbsp;Defa Hou ,&nbsp;Yi Lu ,&nbsp;Fulin Yang ,&nbsp;Can Liu ,&nbsp;Xu Lin ,&nbsp;Zhifeng Zheng ,&nbsp;Yunwu Zheng","doi":"10.1016/j.fuproc.2024.108034","DOIUrl":"https://doi.org/10.1016/j.fuproc.2024.108034","url":null,"abstract":"<div><p>To develop a structure-tailoring catalyst for catalytic conversion of lignin for value-added chemicals, a series of novel Fe-Ce-Al metal oxide catalysts was synthesized via different methods to tailor activity and structure for catalytic pyrolysis of lignin to enhance hydrocarbon-rich bio-oil. The results revealed that FeCeAl-CO catalysts derived from coprecipitation method with smaller particle sizes exhibited excellent catalytic deoxygenation activity due to higher Lewis/Brønsted acid, reversible Ce<sup>3+</sup>/Ce<sup>4+</sup> redox pairs, tailorable oxygen vacancies and promoted β-O-4, aromatic-OCH<sub>3</sub> and side-chain cleavage. Additionally, coprecipitation method was facilitated to enhance hydrogen transfer, side-chain cleavage and aromatization reactions, while wet impregnation was beneficial to enhance demethoxylation and H-abstraction activity. During catalytic pyrolysis process, over 57.91% of hydrocarbon, including 20.21% and 25.71% for aromatics and olefins were achieved over FeCeAl-CO catalyst. Over 60.74% phenols and 52.48% alkylphenols were obtained over Fe-Ce/Al<sub>2</sub>O<sub>3</sub>-IM catalyst due to synergistic effect of FeOx and CeOx species. Fe-Ce-Al catalyst exhibited great activity and stability after fourth run, greater Brønsted acid-favored lignin cleavage and coke deposition, and metal active species leaching, oxidation and pore blockage were the key reasons for deactivation. Therefore, these findings could provide a cost-effective method for designing structure-tailoring catalysts for direct catalytic deoxygenation of lignin to generate hydrocarbon-rich upgrading bio-oil.</p></div>","PeriodicalId":326,"journal":{"name":"Fuel Processing Technology","volume":"254 ","pages":"Article 108034"},"PeriodicalIF":7.5,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0378382024000043/pdfft?md5=c6d3162c90a33fc6af5fd3c4f1c188ca&pid=1-s2.0-S0378382024000043-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139419346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
