To verify their suitability for the process, the synthesized catalyst was characterized using Scanning Electron Micrograph (SEM), X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Fluorescence (XRF), and Braut Emmet Teller (BET). The biodiesel was characterized using GCMS (Gas Chromatography Mass Spectrometer) and FT-IR. Kinetic data using CD-BaCl-IL catalyst were obtained at 4 wt% catalyst, 2 hours reaction time, 300 rpm, 10:1 methanol/oil ratio, and 60 °C. Two elementary reaction mechanisms, Eley-Rideal (ER) and Langmuir-Hinshelwood-Hougen-Watson (LHHW) were employed to evaluate the kinetics. The kinetic analysis indicated that the LHHW model accurately represented the experimental data, exhibiting favorable parameters, an R<sup>2</sup> value of 0.999, and a variance of 2.61E-14 at 40°C. The rate-determining step (RDS) was the surface reaction that connected the adsorbed triglyceride and adsorbed alcohol. The rate rose as the temperature increased, suggesting an endothermic process. At a temperature less than the boiling point of alcohol, the frequency factor and activation energy for the reaction were 6.33E6h-1 and 45.3 kJ/mol, respectively. The feasibility of the CD-BaCl-IL catalyst was ascertained as the LHHW model determined that the RDS and the SB fuel properties complied with the ASTM D 6751 standards.</div></div>","PeriodicalId":101197,"journal":{"name":"Sustainable Chemistry One World","volume":"6 ","pages":"Article 100057"},"PeriodicalIF":0.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Saponin, a secondary metabolite in numerous plants, offers eco-friendly and sustainable alternatives for a wide range of biomedical applications. Saponin was isolated from soapnut in an aqueous medium and a standard protocol for green synthesis of saponin-capped copper oxide nanoparticles was optimized.

X-ray diffraction confirmed the formation of CuO in both samples and UV–Vis and Fourier transform infrared spectroscopies confirmed the presence of saponin in the green-synthesised samples. Scanning electron microscopic analysis of the samples revealed the formation of bigger nano-spheroids for bare CuO (average diameter 244.1 ± 36.3 nm) and smaller irregular clusters for saponin-capped CuO (average length 147.1 ± 41.6 nm).

It explores how operating parameters, such as temperature, heating rate, and residence time, influence the yield and quality of pyrolysis products, biochar, bio-oil and gas. The findings demonstrate that slow pyrolysis, conducted at lower temperatures and longer residence times, yields higher biochar, while fast pyrolysis, with higher temperatures and shorter residence times maximizes bio-oil production. Intermediate pyrolysis balances biochar and bio-oil outputs, whereas flash pyrolysis favors biofuel production with faster heating rates. Catalytic fast pyrolysis demonstrates strong potential for producing high-value hydrocarbons. Microwave-assisted pyrolysis of macroalgae produces significant syngas and bio-oil with high heating values and lower oxygen content. Additionally, co-pyrolysis with suitable co-feedstocks further enhances bio-oil properties. This study highlights the potential of macroalgae as a renewable resource, emphasizing the versatile applications of pyrolysis products. Harvesting macroalgae during the peak growth, optimizing pyrolysis parameters, integrating complementary techniques, and using efficient catalysts can significantly enhance conversion and yields.
