16. Low-Temperature Oxidation of CO and Volatile Organic Compounds over Supported Platinum Catalysts
Sammanfattning : The catalytic oxidation of carbon monoxide (CO) and volatile organic compounds (VOC) is important for the reduction of harmful emissions from both vehicles and from stationary sources. Both these applications suffer from poor catalytic efficiency at lower temperatures. LÄS MER
17. Coke on Supported Palladium and Platinum Catalysts
Sammanfattning : Catalyst deactivation by coke formation has been investigated in three heterogeneous catalytic processes, propane dehydrogenation, acetylene hydrogenation and hydrogenation of vegetable oil. Palladium and/or platinum supported on alumina were used as catalysts in all reactions. LÄS MER
18. Mixed metal oxide - noble metal catalysts for total oxidation of volatile organic compounds and carbon monoxide
Sammanfattning : CO, volatile organic compounds, and polyaromatics areubiquitous air pollutants that give rise to deleterious healthand environmental effects. Such compounds are emitted, forinstance, by the combustion of wood, particularly fromsmall-scale heating appliances. LÄS MER
19. 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
20. Deactivation of Catalysts and Reaction Kinetics for Upgrading of Renewable Oils
Sammanfattning : The transport sector is one of the main contributors of greenhouse gas emissions in the world. Advanced biofuels from renewable oils can play a decisive role in reducing carbon emissions from the transport sector. Advanced biofuels from waste streams like tall oil, used cooking oil etc. LÄS MER
