Liquid organic hydrogen carriers (LOHC) can be used as a lossless form of storage at ambient conditions. The cycle consists the exothermic hydrogenation hydrogen-lean molecule start transport, usually production site, becoming hydrogen-rich molecule. This loaded transported long distances or long-term due to its ability not lose over periods time. At site time required production, released through an endothermic dehydrogenation reaction. LOHCs show similar properties crude oils, such...

Polyethylene terephthalate (PET) is a thermoplastic polymer which the most used polyester in plastics industry present day. It predominately to construct clothes fibres and food containers due its properties. The problems surrounding this phenomenon are basis for decision produce plant facility. An alternative method of recycling PET perform chemical reaction. Eight initial reaction routes were identified narrowed down three final processes according their economic viability sustainability:...

Catalytic hydrotreatment (HT) is one of the most important refining steps in actual petroleum-based refineries for production fuels and chemicals, it will play also a crucial role development biomass-based refineries. In fact, utilization HT processes upgrading biomass and/or lignocellulosic residues aimed to synthetic chemical intermediates represents reliable strategy reduce both carbon dioxide emissions fossil dependence. At this regard, catalytic oils obtained from either thermochemical...

This paper addresses the urgent need for efficient hydrogen storage methods in context of combating climate change and transitioning to sustainable energy sources. Among various options, LiBH4 is highlighted its high volumetric gravimetric densities, critical factors determining suitability applications. However, challenges arise due thermolysis temperature, which poses difficulties, especially applications like automotive use where temperatures are required. The commercial viability remains...

The use of lignin to produce Benzene, Toluene and Xylene (BTX) is a promising pathway strength the economic case, over production advanced bio-fuels alone. In this work, Ce, Na, Pd Fe supported on zirconium oxide were evaluated for ex-situ hydropyrolysis (HyPy)/hydrodeoxygenation (HDO) Etek under mild conditions (600 °C, 1 atmosphere) towards BTX. Fe/ZrO2 was able selectively BTX (67 area%) cycloalkenes (13.5 strongly deoxygenate HyPy oil about 5 wt% oxygen content, resulting in an with...

Hydropyrolysis of lignin to BTX provides a renewable route for aromatics. Fe catalysts in hydropyrolysis offer efficient deoxygenation, aromatics formation and stability. Techno-economic assessment predicts profitability with optimized bio-oil yield.

A novel catalytic Ru–PES membrane has been synthesised, characterised and evaluated for the selective hydrogenation of furfural to furfuryl alcohol. The exhibited an high activity towards alcohol (selectivity >99%) with turnover frequency (TOF) as 48 000 h⁻¹.

A supported Pd-Au (Au 7wt%) membrane was produced by electroless plating deposition. Permeation tests were performed with pure gas (H₂, H₂, N₂, CO₂, CH₄) for long time operation. After around 400 h under testing, the composite achieved steady state condition, an H₂/N₂ ideal selectivity of 500 at 420 °C and 50 kPa as transmembrane pressure, remaining stable up to 1100 Afterwards, allocated in a reactor module methane steam reforming reaction tests. As preliminary application, °C, 300 space...

The catalytic hydrogenation of lignocellulosic derived bio-oil was assessed from the thermodynamic simulation perspective, in order to evaluate its economic potential for production added-value chemicals and drop-in fuels. A preliminary evaluation first run identify conditions where process is profitable, while a full analysis evaluated how operating affected reaction terms yield. results indicate that should be separated into water-soluble insoluble fractions previous hydrogenation, since...

A series of monometallic and bimetallic metal catalysts (Pd, Cu, Fe, PdCu, PdFe) supported on ZrO2 (6–8 nm) were synthesized tested for the hydrogenation bio-oil model compounds (furfural, vanillin, glucose) under 50 bar H2 at 100 °C. The fully characterized their properties related to catalytic activity. PdFe PdCu displayed enhanced performance compared aldehyde glucose). For best catalyst, 98% vanillin alcohol (VA) 65.5% furfuryl (FA) conversion was obtained 80 min batch-time. showed high...

Recently RFID technology has made its way into end-user applications, enabling automatic item identification without requiring line of sight. In particular passive tags provide a promising, low cost and energy-efficient solution for inventory applications. However, their large-scale adoption strictly depends on the efficiency process. A major challenge is how to arbitrate channel access so that all are able answer reader inquiries identify themselves over time. This paper stems from...

A rise in CO2 and other greenhouse gases’ concentration from gas refinery flares furnaces the atmosphere causes environmental problems.
