16. Production of Hydrogen for Oil Refining by Thermal Gasification of Biomass: Process Design, Integration and Evaluation
Sammanfattning : Hydrogen is an important part of crude oil refining operations since it is required in several units for the desulphurization and upgrading of various oil fractions. At present, most of the refineries meet their hydrogen demand through methane steam reforming, a refinery unit that can represent up to 25% of the plant’s fossil CO2 emissions. LÄS MER
17. Biomass Gasification-Based Biorefineries in Pulp and Paper Mills – Greenhouse Gas Emission Implications and Economic Performance
Sammanfattning : The pulp and paper industry has a great opportunity to take advantage of the experience about forestry and wood handling for production of renewable fuels, chemicals and materials. Residues from forestry, i.e., tops, branches and stubs, have great potential to become a raw material that can replace crude oil or natural gas in many applications. LÄS MER
18. Fluidized bed plants for heat and power production in future energy systems
Sammanfattning : Fluidized bed (FB) plants are used for heat and power production in several energy systems around the world, with particular importance in systems using large shares of renewable solid fuel, e.g., biomass. LÄS MER
19. Hydrogen Production by Integration of Fluidized Bed Heat Exchanger in Steam Reforming of Natural Gas
Sammanfattning : The possibility to integrate fluidized beds as heat sources for steam reforming in hydrogen production plants is examined in this work. Sites with large-scale production and consumption of hydrogen such as refineries are considered as especially interesting. LÄS MER
20. Novel catalysts development for NOx reduction from H2 combustion engines
Sammanfattning : Hydrogen, as a clean energy carrier, burns without producing any carbon emissions. Hydrogen internal combustion engines (H2-ICE) are considered an alternative for the transition from conventional fossil-fuel vehicles. LÄS MER
