This study addresses the growing demand for sustainable chemical processes that produce key intermediates, such as ethylene and diethyl ether, from renewable resources. The research examined the effect of varying WO<sub>3</sub> loadings on catalyst performance using the incipient wetness impregnation method. The physicochemical properties of catalysts were elucidated through a variety of characterization techniques. The results revealed that MMT supports exhibited a more significant enhancement in catalytic efficiency compared to AC when loaded with W. This superior performance is attributed to MMT’s unique layered structure, enabling efficient dispersion of tungsten species and optimized acid site distribution. The structural properties of the support and the higher density of weak acid sites were found to significantly influence catalytic activity. The 13.5WMMT catalyst demonstrated remarkable dual functionality, achieving 42.63 % diethyl ether yield at 250 °C and 96.73 % ethylene yield at 400 °C. In contrast, the 13.5WAC catalyst produced only 22.30 % diethyl ether yield at 300 °C and 77.02 % ethylene yield at 400 °C. The study not only underscores the significance of metal loading and support type in achieving superior catalytic performance, but also highlights the exceptional potential of MMT as a promising candidate for sustainable and efficient ethanol dehydration processes.</div></div>","PeriodicalId":52958,"journal":{"name":"Carbon Resources Conversion","volume":"8 1","pages":"Article 100303"},"PeriodicalIF":6.4,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143154663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Co-pyrolysis was chosen for its potential to improve the quality of pyrolytic oil by generating synergistic effects between two distinct feedstocks, reducing activation energy, and enhancing pyrolytic oil quality. The central composite design (CCD) of response surface methodology (RSM) was used to optimise the temperature and EFB ratio. Atomic absorption spectrometry (AAS) was employed to characterise the heavy metal concentration in the pyrolytic oil. The optimised pyrolytic oil (UE450) produced the highest oil yield (25.17 wt%) with the lowest metal concentration at 450 °C with a 50 % EFB ratio. The fuel’s characteristics were similar to those of conventional diesel, with a higher value of HHV (45.17 MJ/kg). However, the oil was slightly acidic, with a pH of 4.3. GC–MS analysis of UE450 revealed the presence of alkanes and monoaromatic-rich hydrocarbons. Additionally, the UE450 biochar was characterised using FTIR, FESEM, and XRF. FTIR analysis showed that the carbonyl group (C = O) peaks at 1730 and 1440 cm<sup>−1</sup> disappeared, indicating that heavy metals were bound to the biochar surface. Likewise, XRF analysis of UE450 biochar revealed that zinc (Zn) exhibited a high metal adsorption capacity, following the sequence Zn > Fe > Pb (1.96, 1.06, and 0.81 mmol/g). The XRF results also indicated a significant removal of SO<sub>3</sub> at approximately 10.37 mmol/g.</div></div>","PeriodicalId":52958,"journal":{"name":"Carbon Resources Conversion","volume":"8 1","pages":"Article 100300"},"PeriodicalIF":6.4,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143154099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, most of catalytic gasification experiments on coal char particles are analyzed by thermogravimetric analyzer (TGA). However, the gasification agent will be subject to diffusion resistance during the reaction because of the sample stacking, making the inherent reaction kinetics unclear. In this study, we investigated the catalytic gasification behavior of single-particle coal char using high temperature stage microscope (HTSM). With the diffusion resistance ruled out, the reaction conditions when using a HTSM are more similar to those inside a real industrial gasifier. Numerical models of the gasification reaction of single-particle coal char were further developed using the kinetic parameters obtained under HTSM. Three models were investigated, including regular spherical structured, irregular spherical structured and porous spherical structured models, representing different morphologies of coal char particles in the gasifier. The gasification characteristics of coal char particles under different K<sub>2</sub>CO<sub>3</sub> catalyst loadings and gasification temperatures were also studied. Compared with the activation energies data of coal char particles without catalyst, the activation energies of coal char particles loaded with 2.2 %, 4.4 %, 6.6 %, and 10.0 % catalysts were reduced by 110 kJ/mol, 116 kJ/mol, 121 kJ/mol, and 126 kJ/mol, respectively.
