Fuel-specific devolatilization parameters for detailed comparison of pulverized biomass fuels

Comparison of Devolatilization Technologies for Viscous Polymers

Devolatilization of solvents from viscous polymer cement is realized through stripping of solvent with steam in stirred vessels or directly by evaporating the solvent from the polymer. The later so-called direct desolventizing is realized in extruders or high volume kneaders. All 3 methods involve additional energy to drive out solvent either by partial pressure through additional steam (steam ...

Hydrogen as Aviation Fuel: a Comparison with Hydrocarbon Fuels

Depletion of fossil fuels and environmental considerations have led engineers and scientists to anticipate the need to develop a clean, renewable and sustainable energy system. In general, they agree that in such a system hydrogen will be used as an energy carrier. One of the areas in which hydrogen will be replacing fossil fuels is air transportation, an area that has been under research for s...

Processing Woody Debris Biomass for Co-Milling with Pulverized Coal

The USDA, Forest Service, Forest Products Lab funds several grants each year for the purpose of studying woody biomass utilization. One selected project proposed removing small diameter stems and unmerchantable woody material from National Forest lands and delivering it to a coal-fired power plant in Alabama for energy conversion. The Alabama Power Company will test the utilization of the woody...
