SCCER BIOSWEET Annual Conference 2019

The 6th Biomass for Swiss Energy Future Conference was held at HSLU in Horw on September 3, 2019. Approximately 80 attendees listened to nine presentations, studied the 35 posters along the most relevant biomass value chains in Switzerland, and networked with members of the biomass energy research community and with technology application partners. This year‘s event focused on producing…

Cu–Al Spinel as a Highly Active and Stable Catalyst for the Reverse Water Gas Shift Reaction

The reverse water gas shift reaction is considered to be a highly attractive catalytic route for CO2 recycling in a future sustainable economy. Copper-based catalysts are commonly used for this reaction due to their high activity and selectivity. However, their low thermal stability is problematic for long-term usage. Here, we introduce an in situ formed…

Scale-up methodology for automatic biomass furnaces

This work presents a methodology to perform the scale-up of a solid fuel furnace to a higher heat output with maintaining or improving the burn-out quality. As basis to derive the scale-up concept, an example of a 35 kW screw burner for biomass fuels is investigated. Based on the Pi-theorem, the relevant dimensionless parameters are derived and similarity rules for the…

A combined hydrothermal gasification – solid oxide fuel cell system

Hydrothermal gasification (HTG) is a promising technology that allows the recovery of nutrients from wet biomass with simultaneous production of an energy-rich gas. In this work, wastewater effluent (leachate) obtained from a composter sanitary system operating without external connection to sewer pipes was used as a feedstock for HTG process. The leachate effluent was characterized…
