1. Fluid Catalytic Cracking Catalyst Demetallization and Reactivation, Modeling of Catalytic Cracking, and Use of Microwaves to Heat Fluid Beds
Sammanfattning : The fluid catalytic cracking unit (FCCU), the major conversion unit in an oil refinery, uses a silica-alumina zeolite catalyst to convert heavy hydrocarbons to light hydrocarbons. A small fraction of the catalyst must be continually replaced with fresh catalyst to maintain activity. LÄS MER
2. Catalytic Steam Pyrolysis of Biomass for Production of Liquid Feedstock
Sammanfattning : The current societal needs for fuels and chemical commodities strongly depend on fossil resources. This dependence can lead to economic instabilities, political problems and insecurity of supplies. LÄS MER
3. Thermochemical and Catalytic Upgrading in a Fuel Context : Peat, Biomass and Alkenes
Sammanfattning : .... LÄS MER
4. Catalytic pyrolysis of lignin to produce fuels and functional carbon materials
Sammanfattning : Development of renewable energy carriers and green adsorbents is an essential step in creating a fossil-free and toxin-free future of the world. Lignin is the second highest component of biomass and the only renewable resource of aromatics in nature. LÄS MER
5. Steam Cracking of Polyolefins in Fluidized Bed Systems: Influences of the Bed Materials on the Hydrogen Transfer Reactions
Sammanfattning : Plastic materials are crucial to the supply of everyday necessities, such as clothes, packaging, and building materials. Most plastic materials are disposed of after a short period of use due to their low cost of production. The linear use of plastics has resulted in high levels of plastic waste materials. LÄS MER
