It is shown that HEFA-SPK produced from UCOs with low concentrations of C18:1, high concentrations of C18:2, and low H/C ratios utilize less energy and more hydrogen during Fuel Production. Hence, HEFA-SPK produced from such UCOs will embody higher gCO2e for fossil hydrogen utilization scenarios, and lower gCO2e for green hydrogen utilization scenarios compared with other UCOs. Conversely, it is shown that HEFA-SPK produced from UCOs with high concentrations of C18:1, low concentrations of C18:2 and high H/C ratios utilize more energy and less hydrogen during Fuel Production. Hence, HEFA-SPK derived from such UCOs will embody lower gCO2e for fossil hydrogen utilization scenarios, and higher gCO2e for green hydrogen utilization scenarios compared with other UCOs. Monte Carlo simulation gives the emissions embodied in Fuel Production a 95% confidence interval for all UCO-derived HEFA-SPK, showing a similar uncertainty for all compositions. A maximum of +1.1 gCO2e/MJSAF and −1.0 gCO2e/MJSAF is obtained for the upper and lower bounds respectively for the emissions embodied during HEFA-SPK production from UCO. The application of the correlations founded in this study allows for the prediction of the specific emissions embodied in the feedstock-to-fuel conversion of any UCO, providing the C18:1 concentration, C18:2 concentration, H/C ratio and H/O ratio of the UCO is known.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"18 4","pages":"837-854"},"PeriodicalIF":3.2,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bbb.2653","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141663167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hemicellulosic hydrolysate was composed of xylosaccharides 24.8 g L–1 (mainly xylose, 20.3 g L–1), acetic acid 7.8 g L–1, furfural 0.7 g L–1, and acid-soluble lignin (ASL) 2.1 g L–1. It was subsequently purified by using anion exchange or adsorption resins. Different liquor-to-resin ratios were evaluated to obtain a high concentration of xylosaccharides in the eluate and thorough removal of components that inhibit lactic fermentation. The best performance was observed when using Amberlite-XAD-4 resin at a liquor-to-resin ratio of 3:1. An eluted hydrolysate was obtained, preserving 80% of the xylosaccharides and effectively removing almost all furfural, 90% of ASL, and 32% of acetic acid.

In Serbia, the contamination primarily involved heavy metals, whereas the Lithuanian site was predominantly contaminated with hydrocarbons from petroleum products. The harvested biomass underwent pretreatment and was then used as feedstock for conversion into high-energy carriers.

Comprehensive analyses were conducted for all of the catalysts, considering their structural, compositional, morphological characteristics, and basicity, to understand them in greater depth. Among these analyses, gas chromatography was employed to examine the composition of the reaction products. The investigation extended to a recycling study under optimized conditions. Thermogravimetric analysis and X-ray photoelectron spectroscopy were used to characterize the spent catalysts. Catalytic activity was found to be influenced strongly by the fluorine content, demonstrating remarkable performance for the materials containing fluoroperovskites such as KMgF3 in the catalyst KMgAFC, and K2ZnF6 in KZAFC. Remarkably, KZAFC with 20% fluorine exhibited superior glycerol conversion (68%) and selectivity for diglycerol (27%). Comparative analysis with ZnAl-layered double hydroxide highlighted the positive impact of fluorine on catalytic activity. Introducing a calcination step in the catalyst recovery process also demonstrated improved activity during recycling. Interestingly, KZAFC exhibited stability over four reaction cycles, presenting an economic advantage over homogeneous catalysts. The study also shed light on the potential fluorine loss at the surface and potassium leaching into reaction products, correlating these phenomena with the observed decline in activity. These comprehensive findings contribute significantly to advancing sustainable glycerol valorization through heterogeneous catalysis.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"18 5","pages":"1613-1630"},"PeriodicalIF":3.2,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141673300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding and controlling the mechanisms of such deposition is essential in developing a techno-economically viable industrial application for the production of synthesis gas and/or hydrogen. The patent-pending nickel-supported upgraded slag oxide (Ni-UGSO) catalysts, in powder form, have demonstrated excellent performance and achieved equilibrium in dry reforming, steam reforming and mixed methane reforming in a gram-scale laboratory packed bed reactor under barometric pressure. In this extended study, Ni-UGSO pellets were prepared using the wet impregnation method. The pelletized form of said catalyst was studied under elevated pressure to imitate the industrial operating conditions in a kilogram-scale laboratory packed bed reactor. The characterization of the fresh and used catalytic formulation produced data allowing the investigation of the physicochemical properties of catalysts and the effects of metal dispersion, reaction pressure and crystallite size, as well as the role of side reactions on the nature of the coke. The metal support nature favored the interaction between the Ni metal and spinels (UGSO), and the presence of the clay binder (kaolinite, quartz) improved the pellet morphology, provided higher Ni dispersion, maintained the crystallite size, reduced the coke formation and achieved similar or higher performance with respect to Ni-UGSO powder despite having 85% less surface area. The Ni-UGSO pellet showed negligible coke deposits from 1 to 6.5 atm and operated successfully for 24 h at 5.5 atm, 800°C and gas hourly space velocity 810 L/(h kg cat). This study provides new insight into the design of a more efficient and robust catalyst for methane dry reforming at elevated pressures, which is critical for potential future transfer at the industrial level.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"18 4","pages":"1027-1046"},"PeriodicalIF":3.2,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141682931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to study the effect of varying the stainless-steel-based combustion compartment volume of a biomass-fueled top-lit updraft gasifier on the groundnut shell biochar. The biochar yields for reactors ranged from 34.9% to 51.2%. The sample produced in the smallest combustion compartment volume showed the highest carbon content, according to energy dispersive X-ray spectroscopy (EDX) analysis. Potassium, another major element, decreased as the combustion compartment was reduced. Scanning electron microscopy (SEM) analysis revealed that the biochar samples produced had an irregular shape and rough surfaces, and reducing the combustion compartment volume resulted in larger particles on the surface. Fourier transform infrared (FTIR) spectroscopy analysis showed similarities and differences in peaks observed for all the samples. The biochar samples produced can find applications in wastewater treatment, energy conversion and storage, and soil amendment, and the findings contribute to the design and optimization of biomass-based gasifiers.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"18 5","pages":"1598-1612"},"PeriodicalIF":3.2,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141687121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dairy biogas, a renewable byproduct of dairy farming, was compared with hydrogen in terms of operational efficiency. The investigation focuses on the performance parameters and efficiency metrics of MCFCs when powered by dairy biogas, relative to natural gas and hydrogen. The results demonstrate that while dairy biogas can power MCFCs, its efficiency and fuel utilization rates are lower than those of conventional fuels. This study contributes to an understanding of alternative, sustainable fuel sources for MCFC operations. During the study, the performance parameters of dairy biogas were compared with hydrogen, which served as a benchmark fuel. It was observed that in comparison with natural gas, commonly used as a fuel, dairy biogas showed lower efficiency rates and reduced fuel-utilization factors. This suggests that although dairy biogas can be used as a fuel source for MCFCs, its effectiveness might not be on par with traditional fuels like natural gas.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"18 4","pages":"990-999"},"PeriodicalIF":3.2,"publicationDate":"2024-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141730199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initial results have shown that coupling dark fermentation and anaerobic digestion is not only possible but also advantageous. Specifically, by integrating dark fermentation in existing biogas plants, the overall physical efficiency of the process's substrate turnover can be increased by up to 50% through providing hydrogen in addition to biogas. The achieved test results are examined based on limit-oriented physical efficiency evaluation to show the potential for optimization of the substrate turnover in biological concepts based on modeling.
