1. Development of a methanol reformer for fuel cell vehicles
Sammanfattning : Vehicles powered by fuel cells are from an environmentalaspect superior to the traditional automobile using internalcombustion of gasoline. Power systems which are based upon fuelcell technology require hydrogen for operation. The ideal fuelcell vehicle would operate on pure hydrogen stored on-board. LÄS MER
2. RhPt and Ni based catalysts for fuel reforming in energy conversion
Sammanfattning : Although current trends in global warming are of great concern, energy demand is still increasing, resulting in increasing pollutant emissions. To address this issue, we need reliable renewable energy sources, lowered pollutant emissions, and efficient and profitable processes for energy conversion. LÄS MER
3. Hydrogen Production by Integration of Fluidized Bed Heat Exchangers in Steam Reforming
Sammanfattning : The possibility to integrate fluidized beds as heat sources for steam reforming in industrial hydrogen production plants is examined in this work. The proposed processes include traditional catalytic steam reforming of natural gas (SMR), shift reactors and purification steps; the main difference is the reformer furnace. LÄS MER
4. 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
5. Hydrogen generation from dimethyl ether by autothermal reforming
Sammanfattning : Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. LÄS MER
