This review summarises the principal factors governing the yield/selectivity of furfural by solvolysis technique, with a particular attention to the conversion of C6 cellulose feedstock. So far, most studies focused on the C5 sugar-rich feedstock, which requires solely dehydration to convert into furfural. In contrast, the conversion of C6 sugars to furfural is more challenging, requiring dehydration and C<img>C bond breakage. Depending on the type of biomass and catalyst, the reaction temperature and residence time have an optimum value of ∼160–180 °C and ∼ 30–120 min respectively in traditional heating mode. The low optimum temperature (∼140 °C) for the microwave-assisted technique and that C5 polymers do not necessarily require longer reaction time than their monomers indicate that microwave irradiation is more efficient in depolymerisation reaction of polymers. Additionally, the organic solvent systems containing &lt;10 wt% water were the most promising. For catalysts, sulphates/sulphonated catalysts showed the highest potential for furfural production, and Zn<sup>2+</sup>, Cu<sup>2+</sup> and Fe<sup>3+</sup> are the most promising cationic candidates. Finally, the future perspectives were proposed, including development of novel heterogeneous catalysts and microwave-assisted technique, kinetic study and mechanistic study for the conversion of C6 sugars.</p></div>","PeriodicalId":326,"journal":{"name":"Fuel Processing Technology","volume":"255 ","pages":"Article 108063"},"PeriodicalIF":7.5,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S037838202400033X/pdfft?md5=8903d4c4532866ea2d624da16f2951a5&pid=1-s2.0-S037838202400033X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139975835","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}

This research investigates the impact of the mass ratio of RCTP and BIMNP on the composition, molecular structure, and thermophysical characteristics of the co‑carbonized pitch. A tentative elucidation of the co‑carbonization mechanism involving RCTP, BIMNP, and BC is presented.

The resulting carbon fibers experience a rise in tensile strength by 947 MPa and an increase in Young's modulus by 41.3 GPa as BIMNP content varies from 10% to 30%.

The formation process of soot includes six steps: fuel pyrolysis, soot nucleation, coalescence, surface growth, aggregation, and soot oxidation. However, the formation of soot is very complex and is influenced by factors such as fuel type, combustion conditions, and environmental temperature. Oxygenated fuels additives have a positive effect on reducing soot emissions, but recent studies have shown that oxygenated fuels can lead to an increase in the number of small particles of soot. In this paper, the effect of oxygenated fuel additives such as alcohol, ether, and esters on soot emissions is discussed in terms of the mechanism of soot formation. Subsequently, the role of after-treatment systems in reducing soot emissions is summarized. This work can update our understanding of the impact of oxygenated fuels on soot emissions.</p></div>","PeriodicalId":326,"journal":{"name":"Fuel Processing Technology","volume":"254 ","pages":"Article 108046"},"PeriodicalIF":7.5,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S037838202400016X/pdfft?md5=6d4bf9d50b0d8118600b8f5499f0b862&pid=1-s2.0-S037838202400016X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139648990","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}
