However, utilization of CO-rich or H₂-rich gas of strong reducibility as reducing agent for magnetization roasting would lead to over-reduction of Fe₂O₃ in the ore to non-magnetic FeO, which makes the magnetism of the roasted ore be lower than its maximum, and hence leads to a lower iron recovery than expected. To explore the possibility of using CH₄ as reducing agent for controllable reduction of Fe₂O₃ in iron ores to selectively forming magnetic Fe₃O₄, i.e., for maximizing the magnetism of the reduced ore for efficient iron separation and recovery, a series of fluidized bed reduction tests in CH₄ were carried out on two iron ores of 55 % and 33 % iron at different temperatures for different periods of time, and the resultant reduced ore particles were magnetically separated for recovery of iron concentrate. XRD and ICP analyses were performed on all recovered iron concentrates to identify the crystal forms of their iron species and to quantify their iron contents. The results have shown that the controllable reduction by CH₄ of Fe₂O₃ in the iron ores to strongly magnetic Fe₃O₄ can be realized by controlling the reduction temperature and time condition applied. The resultant concentrates can be fully recovered by magnetic separation in a weak magnetic field of 60 kA/m to attain a maximum iron recovery of 98 % for the high-grade ore and that of 65 % for the low-grade ore. Besides, the results have also shown that the most critical factor affecting the controllability of the ore reduction process and the selectivity to the generation of magnetic Fe₃O₄-containing particles is the reduction temperature, and that the upper temperature threshold for the controllable reduction and selective generation of strongly magnetic iron concentrate is about 650℃.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 1","pages":"Article 100078"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141698256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biochar has emerged as an eco-efficient catalyst support material. In this study, biochar derived from corn stover (BCS) was first used as a metal catalyst support material for xylose hydrogenation into xylitol. The catalyst was prepared by carbonizing corn stover (CS), impregnating the resulting biochar with metal, and reducing the metal-impregnated BCS. The catalyst characteristics were comprehensively explored. The Ru/BCS catalyst was employed in xylose conversion to xylitol at different process temperatures (100 – 160 °C), retention times (3 – 12 h), H₂ pressures (2 – 5 MPa), and Ru contents (1 – 5 %). The highest xylitol yield (87.0 wt.%) and selectivity (91.6 %) were derived at 120 °C for 6 h under 4 MPa H₂ using 5 % Ru. Interestingly, the Ru/BCS catalyst showed high stability under the promising process condition. Additionally, xylitol production from hydrolysates enriched with CS xylose was subsequently explored. On the other hand, the catalyst characterization results revealed that the superior catalytic efficiency of 5Ru/BCS was mainly due to the metal nanoparticles embedded in the biochar. Additionally, BCS proved to be an outstanding support material for a bimetallic hydrogenation catalyst (Ru-Ni/BCS). Therefore, these results indicate that BCS can be a competitive support material for metal hydrogenation catalysts, enhancing environmental friendliness and potentially being employed in industrial-scale xylitol production.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 1","pages":"Article 100083"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This comprehensive review explores the evolving landscape of unconventional oil resources, focusing on the environmental and economic implications of bitumen partial upgrading technologies, particularly within the Canadian context. With over 55 % of the world's oil reserves comprising of unconventional oil, which includes extra-heavy oil and oil sand bitumen, there is a growing trend to shift from traditional oil sources to these abundant yet under-utilized reserves. This review delves into the challenges and advancements in bitumen partial upgrading, highlighting the latest technologies in thermal cracking, hydrocracking, catalytic cracking, and innovative methods like surfactant integration, cavitation, microwave, and plasma-assisted upgrading. It also discusses the environmental implications and economic feasibility of these technologies, emphasizing the necessity for sustainable and cost-effective solutions at petroleum field sites. Furthermore, the report introduces the transformative concept of Bitumen Beyond Combustion (BBC), which explores the non-combustion uses of bitumen and its asphaltene fraction in manufacturing high-value carbon-based products. These novel approaches align with global sustainability goals, offering the potential for significant reductions in greenhouse gas emissions and new routes to diversify the economic applications of bitumen. The review then concludes with an assessment of current challenges and future research directions, advocating for a balanced approach that harmonizes technological innovation, environmental stewardship, and economic viability in the field of bitumen upgrading.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 1","pages":"Article 100084"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conversion of toluene into higher value chemicals (benzyl alcohol, benzaldehyde, and benzoic acid, etc.) using sunlight is a very promising means. To achieve the full conversion and utilization of toluene, it is necessary to construct photocatalysts with high conversion and selectivity while synergistically optimizing the optimal reaction environment to significantly affect the photoconversion of toluene. High-performance photocatalysts not only widely absorb sunlight, but also have abundant active sites and generation of free radicals, which can promote the chemical bonds cleavage of toluene, thus greatly increasing the yield of higher-valued products. In addition, the type of photocatalyst and the modification strategy would influence the selectivity of toluene photo-conversion. Therefore, it makes sense that this review presents the reaction mechanism and the influence of reaction factors for the (mainly) photo-oxidation of toluene, a thorough analysis and prediction of the reaction mechanism by theoretical calculations, and the toluene oxidation by different photocatalysts (in particular halogen-containing perovskite materials) to yield specific products, as well as photocatalysts’ modifications.
