This paper presents an experimental study of the spreading dynamics of droplets of liquids with a temperature-dependent viscosity on a heated horizontal sapphire surface. This surface can be heated between 40 and 90°C and allows for usual observation from different directions. The used liquids are glycerol water solutions with a volume percentage of 80%, 85.2%, and 92.8% glycerol, which feature a large dependency of the viscosity on the temperature. Using high-speed imaging and infrared thermography, the shape of the droplet and the temperature of the droplet surface in contact with the surface are measured, respectively. Our experiments reveal that the spreading of the droplets increases with an increase in the surface temperature, which is also expected as the effective viscosity of the liquid will decrease with an increase in the droplet temperature. However, the heating of the droplets ensures that these effects only are apparent after sufficient time to heat the droplet. In addition, the amplitude of the oscillations in the spreading of the surface will increase when the temperature of the surface is increased, which is also related to the decreased viscosity. Finally, the effects on the local spreading cannot be directly correlated to the temperature of the droplet in contact with the surface, which indicates that the viscosity in the droplet is not homogeneous during the experiment and local gradients in the viscosity are important in the overall spreading behaviour of the droplet.","PeriodicalId":9400,"journal":{"name":"Canadian Journal of Chemical Engineering","volume":"103 8","pages":"3971-3982"},"PeriodicalIF":1.6,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cjce.25652","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144551342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biomass utilization leads to a carbon-neutral balance by leveraging its inherent carbon that was absorbed from the atmosphere. While chemical looping combustion (CLC) is a promising carbon capture technology for solid fuels such as coal, this paper further explores the feasibility of using biomass in CLC along with valorization of CO2 to valuable chemicals. A polygeneration approach utilizing biomass has been proposed to produce power and value-added chemicals (methanol and dimethyl ether [DME]), thus yielding an integrated CO2 capture and utilization system. Biomass has a significant amount of oxygen and a higher H:C ratio than conventional fuels like coal. The effect of the same has been analyzed by assessing biomass as a feedstock in the proposed process and evaluating the effect of higher oxygen content towards the objective of CO2 valorization relative to that of coal. Furthermore, a comparative discussion of the suitability of biomass compared to coal from a valorization perspective has been presented. Detailed techno-feasibility analysis on the schemes and optimization studies to maximize the performance of the system in terms of energetics, CO2 mitigation, and profitability has been conducted. From the analysis, it has been identified that the utilization of biomass as a feedstock in CLC-based processes results in higher chemical production rates and higher profits with lesser CO2 emissions than coal. The above analysis and evaluation has been carried out through simulations using Aspen Plus® software.","PeriodicalId":9400,"journal":{"name":"Canadian Journal of Chemical Engineering","volume":"103 8","pages":"3568-3588"},"PeriodicalIF":1.6,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144551101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the current fermentation process faces limitations due to the challenging retrieval of the lactic acid product from the fermentation broth, resulting in the production of gypsum waste in stoichiometric quantities. In this work, we demonstrate the efficacy of Zr-UiO-66 metal–organic frameworks (MOFs) as effective adsorbents in the process of recovery of lactic acid from the fermentation broth. The MOF beads have been manufactured successfully and were applied to recover lactic acid from the solution and the experimental conditions were optimized. The results show that Zr-UiO-66 adsorbent has a good ability of up to 98.8% to adsorb the produced lactic acid from its fermentation broth at a pH value of 6.5, adsorbent (MOF) dosage of 0.625 g, an initial concentration of 15 mg/L, temperature of 298 K, within process time of 4 h. The data obtained from the adsorption process demonstrated a satisfactory fit with the Langmuir isotherm model (with a R2 of 0.958), kinetics (with a R2 of 0.970), and thermodynamic results, confirming the spontaneous and exothermic nature of the adsorption process. The regeneration experiment of the MOF beads showed that the adsorption efficiency of Zr-UiO-66 remained above 90% even after undergoing seven cycles.","PeriodicalId":9400,"journal":{"name":"Canadian Journal of Chemical Engineering","volume":"103 8","pages":"3940-3954"},"PeriodicalIF":1.6,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144551097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
