Solar Fuels II

25 outubro 2019, 14:00 • Francisco Manuel Da Silva Lemos

Diferent range of thermochemical processes under air.

Fundamentals of gasification.

Characteristics of gasification - feedstock and products.

Possibility of producing power and chemicals.

Power production using Integrated Gasification Combined Cycle (IGCC). Advantages of IGCC over boilers for the production of power - flue gas voume and ease of cleaning.

Gasification agents - exothermic (air and oxygen) and endothermic (steam and CO2).

Main gassification reactions and their thermodynamic characteristics.

Usaged of Water-Gas-Shift to adjust the CO/H2 ratio in SynGas.

Gasification reactors - moving bed, fluidised bed and entrained bed.Different zones in a moving bed gasifier.

Brief overview of different proposals for coupling gasification with solar power plants.

Brief introduction to ammonia as an hydrogen carrier.
