The environment is polluted mainly by greenhouse gases, emissions from transportation fuels, etc. Among them, sulfur compounds emitted from the emission of transported fuels significantly impact environmental pollution. It requires the removal of these sulfur compounds from transportation fuels. Refineries use the hydrodesulfurization (HDS) process to reduce these sulfur compounds from fuels. However, the HDS process requires high hydrogen pressure and temperature, making it cost-effective. An alternative to the HDS process is oxidative desulfurization via solvent extraction, which requires low-temperature operating conditions. In this regard, deep eutectic solvents (DESs) are attractive for researchers to desulfurize transportation fuels via solvent extraction due to their low-cost synthesis method. In our study, DESs were synthesized using phenylacetic acid and salicylic acid as hydrogen bond acceptors (HBAs) and tetraethylene glycol as hydrogen bond donor (HBD) in the mole ratio of 1:2. DESs were characterized by using FTIR spectra. Physico-chemical properties of DESs, such as density, viscosity, and refractive Index, were also measured. The synthesized DESs were performed to extract organosulfur compounds from model fuel and actual diesel. An oxidation study was carried out for model fuel and diesel, followed by solvent extraction using these synthesized DESs. The extraction efficiency for PAA/TTEG(1:2) and SAA/TTEG(1:2) was achieved as 50.16% and 38.89% for model fuel at a temperature of 30oC using a solvent to feed ratio of 1.0 while for diesel, it was 38% and 37%. However, it increased to 77%, 68%, and 54%, 73%, respectively, for PAA/TTEG(1:2) and SAA/TTEG(1:2) when the feedstocks were oxidized. These results showed better extraction performance of DES PAA/TTEG(1:2) than that of SAA/TTEG(1:2) at low-temperature 30oC using extractive combined oxidative desulfurization (ECODS). Hence, the DES synthesized using SAA and TTEG in the mole ratio of 1:2 works better as an extraction solvent for removing the organic sulfur compounds from fuels at low temperatures.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135954181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While bushings have grown in size and functionality since their introduction in the early 20th century, manufacturing constraints still limit their full potential. Both in terms of design and quality, traditional manufacturing methods such as milling, drilling and welding limit the potential of precious metal bushings. The technical feasibility of the use of additive manufacturing for the production of bushings is greatly dependent on the material properties. For the purpose of this work, an additively manufactured alloy consisting of 90 wt% platinum and 10 wt% rhodium (PtRh10) is investigated with regard to density, electrical resistivity, creep performance and the contact angle of E-glass on the PtRh10 samples.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67351864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The decrease of resources in the world, along with the growing world population, and the resulting environmental waste, present a fairly significant problem. As an alternative solution to this problem, insects are put forward as an ideal resource. Due to the enzymes and microorganisms in their intestinal microbiota, the biotransformation processes of insects are capable of converting wastes, organic materials, and residues into valuable products that can be used for various industrial applications such as pharmaceuticals, cosmetics, functional food, etc. Some species of insects are in an advantageous position because of the simplicity of their life cycle and the ease of their production and feeding on organic materials to make them valuable products. Considering the sustainability perspective, utilization of the microorganisms or enzymes isolated from these microorganisms available in the microbiota of insects may allow novel insect-based biotransformation processes that promise a more sustainable world and novel green technologies.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67352208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Professor Wilton-Ely is the author of more than 100 publications and was the recipient of the 2021 Sir Geoffrey Wilkinson Award from the Royal Society of Chemistry for his work on metal-based carbon monoxide sensing. He has a strong interest in sustainability, having directed the MRes Green Chemistry course at Imperial College for over 12 years (2010–2022). He has published on the use of recovered metals in catalysis (1–5), the catalytic transformation of biomass to platform chemicals (6–11) and magnetically-recoverable nanoscale catalysts (12, 13). Elemental sustainability is a pressing concern for all researchers using precious metals and this has led Wilton-Ely to work with colleagues to explore the potential for using gold (3) and palladium (4, 5) complexes recovered from end-of-life products in catalysis.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67352252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The characteristics and performance of AC is a result of interaction between source and method of preparation. In the current work, AC has been prepared from date seed wastes using microwave heating under nitrogen using basic (i.e., KOH) / acidic (i.e., H2SO4) chemical activating agents. The AC was characterised using XRD, SEM-EDX, TEM and TGA/DSC. XRD patterns of the AC in both the cases exhibited 3 peaks corresponding to the crystalline graphite form of carbon. SEM images of the freshly prepared carbons showed that the samples contained particles of various sizes including both nanoparticles as well as mm-range particles. DSC analysis showed that the samples exhibited endothermic reaction in low temperature ranges until 300 ◦C and exothermic reaction above this temperature. SEM analysis of the AC, separated into three different size ranges, showed significant etching of the surface of the carbon to yield porous structures. The AC produced using H2SO4 showed better adsorption capacity (9.2 g/g) when compared to that produced using KOH (7.7 g/g). We conclude that the AC prepared from dates seeds can find potential application in water purification and oil spill clean-up.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135758458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
