1. Low temperature catalytic oxidation of CO and reduction of NO with CH4
Sammanfattning : .... LÄS MER
2. 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
3. Ghost in the shell : Studies on subsurface oxygen in oxide-derived copper nanocube catalysts
Sammanfattning : With the passage of time and the advancement of our industrial civilization, environmental concerns have become more and more recognized since the 1990s. Carbon dioxide reduction reactions are capable of converting carbon dioxide into valuable hydrocarbons and reducing the carbon emission from the combustion of fossil fuels. LÄS MER
4. Mild Wet Torrefaction and Characterization of Woody Biomass from Mozambique for Thermal Applications
Sammanfattning : Mozambique has vast forestry resources and also considerable biomass waste material such as bagasse, rice husks, sawdust, coconut husks and shells, cashew nut shell and lump charcoal waste. The potential of the total residues from the agricultural sector and the forest industry is estimated to be approximately 13 PJ. LÄS MER
5. Engineering inorganic nanostructured composites for boosting H2 and O2 evolution reactions
Sammanfattning : Hydrogen is considered a promising energy source with zero emission of CO2; it can provide higher energy density compared to other sources of energy. The amount at which H2 is produced, and the method of production need further improvement for the advancement of hydrogen energy technologies. LÄS MER
