in our current study, supercritical water impregnation (scwi) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. the method allows nano-particles to place on support surfaces in extremely dispersed conditions. the silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...

The low cost of electricity in some areas facilitates the adoption high-temperature electrolysis plants for large-scale storage electricity. Supercritical water gasification (SCWG) is a promising method syngas production from wet biomass. Additionally, it potential source steam electrochemical plants. However, commercialisation standalone SCWG systems hindered by efficiency and high operating c...

Supercritical water gasification (SCWG) has been shown to be an effective technology valorize a wide range of organic waste by transforming them into gases with high energy potential, such as hydrogen and methane. However, the industrial implementation these processes is rarely extended due huge requirements during plant start-up operation. The purpose this study explore feasible ways integrati...

Ru/CNF catalysts of different Ru nanoparticle (NP) sizes (0.9-2.7 nm) were assessed for their performance in continuous supercritical water gasification (SCWG) glycerol. A structure sensitivity was demonstrated, with high initial turnover frequencies (TOF) NPs smaller than 1.2 nm. Deactivation happens essentially through: 1) coking, which occurs more readily at low surface densities and is limi...
