Microwave plasma pyrolysis for the valorization of VFA extracts from HTC process water

(Corresponding) Vakalis S., Liakos D., Papaioannou I., Stefanidis G.
Topic: 
11. ENERGY TECHNOLOGIES
Volatile fatty acids (VFAs) in HTC liquors are a promising but underutilized resource for energy production. This study examines the recovery of VFAs from HTC process water via liquid–liquid extraction and the co-pyrolysis of the recovered stream with methane in a microwave plasma reactor to...Read more

Biogas upgrade with green hydrogen in a semi-pilot trickle bed reactor

(Corresponding) Papadopoulou K., Pavlopoulos C., Riglis C., Tsilifonis E., Markopoulou A., Fotopoulos D., Papathanasiou A., Lyberatos G.
Topic: 
11. ENERGY TECHNOLOGIES
The current study investigated the performance of biological methanation of CO2 using green H2 in a mesophilic (37℃) trickle bed reactor (TBR) (0.051m3) at ambient pressure. For both phase A and phase B a synthetic gas feed (60/40 CH4/CO2) was used to simulate biogas. Nitrogen was used in phase A...Read more

Modelling of Hydrogen Generation from Woody Biomass in a Novel Modular Downdraft Gasifier–WGS–PSA System

Kostopoulou N., Pappa G., Voutsas K., Liakos D., Prinos N., (Corresponding) Vakalis S., (Corresponding) Voutsas E.
Topic: 
11. ENERGY TECHNOLOGIES
An advanced model was developed in Aspen Plus to simulate and optimize hydrogen-rich syngas production from a PP30-scale downdraft biomass gasifier integrated with Water-Gas-Shift (WGS) and pressure-swing adsorption (PSA). The adiabatic model combines equilibrium RGibbs blocks with corrective...Read more
