Nicolas Berguerand presents his lecture for promotion to (oavlönad) docent: "Thermochemical conversion of fuels using catalytic materials in fluidized bed reactors".
Welcome to the seminar room "Earth", the division of Energy Technology, Hörsalsvägen 7A.
After the lecture, coffee and cake is served at the division.
An increased use of sustainable energy sources such as biomass is of great importance if we progressively want to relax our dependence on fossil fuels and minimize their detrimental effect on the environment. For a while, though, fossil fuels still will be used. This means that technologies that allow mitigating CO2 emissions must be part of the transition strategy to meet climate and energy targets. In line with these considerations, Carbon Capture and Storage (CCS) from fossil fuel combustion and biomass combustion/gasification have a strong potential.
Amongst these fields, Chemical-Looping Technologies used for carbon capture or the indirect gasification of biomass rely on circulating fluidized beds. Fluidized beds are attractive, since they induce high fuel conversion and allow fuel flexibility. The bed material does not solely function as a heat carrier for the reactions, but can also play a key role in the chemical conversion routes. Circulating bed materials present many similarities with blood hemoglobin which transports oxygen from the lungs to different body tissues where oxygen is consumed and hemoglobin reduced.
In this lecture, I will highlight the inherent advantages fluidized bed technologies present compared with other thermochemical conversion routes using the hemoglobin analogy as illustration.
