- Co-utilization of solid fuels (coal, biomass) in combustion and gasification processes in fixed bed, entrained flow and fluidized bed reactors. - Development of solid sorbents for CO2 capture from postcombustion gases (CO2/N2), precombustion gases (CO2/H2) and biogas (CO2/CH4). Application in cyclical swing adsorption processes (PSA, TSA, VSA). - Pelletization and torrefaction for the improvement of biomass handleability, grindability and densification.
