The WGS reaction can be efficiently enhanced by the removal of CO2 from the gaseous mixture which shifts the reaction equilibrium towards the products. Hydrogen fraction can reach a value of 100% when the sorbent is not fully covered with the CaCO3 layer. The developed model gives valuable insight into the process specifics and allows for the prediction of operation under various process conditions and also further optimization of the process. With a revolver-type reactor, an almost 90% hydrogen production could be achieved continuously

COBISS.SI-ID: 5790746Compositions having electrocatalytic activity and composites having electrocatalytic activity, as well as processes for making compositions and composites are described. Also, processes for using such compositions and/or composites, such as, for example, a machine or equipment are described. Some aspects of embodiments and/or embodiments of the present invention are directed to a nanosize transition metal alloy (such as for example an alloy and/or one or more intermetallics comprising copper, cobalt, nickel, palladium, platinum, ruthenium, the like, and combinations thereof) that is electrocatalytically active. Some other aspects of embodiments and/or embodiments of the present invention are directed to a composite material comprising a nanosize transition metal alloy and a carbonaceous matrix.

COBISS.SI-ID: 4902938Ash-rich biomass pose severe challenges for any energy recovery because of the low melting point of inorganics. On the other hand, there is huge availability of low-value ash-containing feedstocks such as bark, rice husk and sludge digestate which do not find a proper end use or must be even disposed. The preliminary results obtained using this approach with different ash-rich-containing feedstocks, including bark, rice husks and dehydrated digestate sludge will be presented. All feedstocks were characterized in terms of elemental and proximate analysis, ash content determination and elemental analysis of the ash (Energy Dispersive X-ray spectroscopy). Almost all inorganics in the sludge was successfully removed and the ash-free product had Gross Calorific Value (GCV) of around 21 MJKg-1, even higher than ENplus A1 wood pellets of the best quality. Because of the liquefaction phase involved in the process, the final product can be shaped into any liquid or solid form, e.g. 6 mm diameter EN standardized pellets without the need of any energy intensive procedure. Trails were performed using two alcohols as solvent media, while considerations on the best suitable solvent will also be presented focusing on its recovering procedure. The mass and energy balance considering solvent recovery will be outlined to give a comprehensive picture of the process for industrial application. Process is PCT patent pending.
