Nanotechnology of Catalysis



•Catalysts are perhaps the first industrial nanotechnology
•2-10 nm particles (sometimes larger) on high surface area support (Al2O2, SiO2)
Catalyst Particles

•Catalytic reactions occur on catalyst surfaces

•Small particles maximize surface area
-reduce catalyst volume (smaller reactors)
-optimize use of catalysts
(more metal atoms at surface)

•Catalyst dispersion
fraction of catalyst atoms
at surface (10-40%)

What is Catalysis?

•Berzeliu ....etc

INTRODUCTION TO AMMONIA
________________________________________

Ammonia is one of the most important basic chemical of the world, ranking with materials such as sulfuric acid and sodium carbonate. In the fertilizer field, anhydrous ammonia itself has become the major supplier of the fertilizer nitrogen in India and it is also important inter mediate in production of more complex chemicals.
The major use of ammonia, both directly and indirectly, is as an intermediate in the fertilizer area. There are many othe ....etc

GENERAL INFORMATION
Ammonia is a compound of nitrogen and hydrogen with the formula NH3. It is a colorless gas with a characteristic pungent odor. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceuticals. Although in wide use, ammonia is both caustic and hazardous. In 2006, worldwide production was estimated at 146.5 million ....etc

Abstract
In many areas of the world, finding the type of timber or particle board needed to build a good quality wooden board is becoming a problem. As a result, particle board is beginning to be used by many wooden photo laminators. The information provided in this project report relates specifically to the production of an open fishing photo lamination. It is a simple, easily-formed, room worthy thing. Its general-purpose design is suitable for inside the room/office or around the area.
A general basic knowledge in the use of polyest ....etc
