what are the applications of catalysis in environmental pollution control?

There are tons. Water filtration plants use catalysts, the exhaust on your car uses a catalyst. They are used extensivly due to their ability to readily interact and combine with complex organics.

I'm a little embarrased, but I had to look it up myself. It is a catalyst for hte hydrogenation of alkenes.

Working in environmental analytics, pollution situations are a common experience. One of the most common occurrances of pollution is sullage or liquid manure in surface waters, absolutely deadly for all life forms requiring oxygen from the water, and poisonous for plants in high concentrations, too.\n\nPollution can be quite natural...

Well, the kinetics are actually pretty complicated. \n\nAll of the catalysts I'm aware of for this type of reaction are heterogeneous. This complicates things for several reasons. First, the rate is going to be much more dependent on reactor design since how well the catalyst is suspended and dispersed plays a big role in the rate of reaction. Second, the rate will depend on the active surface area of the catalyst, which can vary from batch to batch of catalyst and must be determined empirically for each sample.  \n\nAnother tricky issue is that in the course of the reaction you are going from a liquid (oil) to solid (fat). This will change the physical properties of your mixture, which changes the way the catalysts is distributed and will certainly change the kinetics. Solution viscosity could potentially become an issue, especially on the industrial scale. It really just depends on how you run the reaction.\n\nIn terms of amount of H2 needed, it's going to depend on precisely what kind of oil you are starting with. Most vegetable oils are mixtures of several oils made of the triacylgylcerides of unsaturated fatty acids such as oleic acid and linoleic acid. Since the degree of unsaturation varies from acid to acid (and therefore oil to oil), it depends entirely on which specific oil you have.\n\nIn terms of catalyst, in principle it's always regenerated and never lost.\n\nI wish I could give you more specifics, but the kinetics here are really messy and not easily amenable to a traditional analysis.

Any of the heavy metals, or benzene products would be excellent topics. If you attempt to present a case on a chemical that's too obscure you'll have a difficult time finding enough research/clinical trials to support your claim. Peruse the EPA website to get some other ideas.

Equilibrium considerations\n\nThe catalyst has no effect whatsoever on the position of the equilibrium. Adding a catalyst doesn't produce any greater percentage of ammonia in the equilibrium mixture. Its only function is to speed up the reaction.\n\nRate considerations\n\nIn the absence of a catalyst the reaction is so slow that virtually no reaction happens in any sensible time. The catalyst ensures that the reaction is fast enough for a dynamic equilibrium to be set up within the very short time that the gases are actually in the reactor.\n\nFinely divided iron and Molybdenum can be used as catalysts.

It's something for chemistry.\nIt's an agent that modifies the effect of other agents.\nIt is roughly the same meaning as a catalyst, as the source points out.\nNever heard the term before, learn something new every day.

Green chemistry is the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances. Whereas environmental chemistry is the chemistry of the natural environment, and of pollutant chemicals in nature, green chemistry seeks to reduce and prevent pollution at its source. In 1990 the Pollution Prevention Act was passed in the United States. This act helped create a modus operandi for dealing with pollution in an original and innovative way.\n\nGreen chemistry is an overarching philosophy of chemistry, rather than a subdiscipline of it. It applies to organic chemistry, inorganic chemistry, biochemistry, analytical chemistry, even physical chemistry. The focus is on minimizing the hazard and maximizing the efficiency of any chemical choice. It is distinct from environmental chemistry which focuses on the chemical phenomena in the environment.\n\nIn 2005 Ryoji Noyori identified three key developments in green chemistry: use of supercritical carbon dioxide as green solvent, aqueous hydrogen peroxide for clean oxidations and the use of hydrogen in asymmetric synthesis [1]. Examples of applied green chemistry are supercritical water oxidation, on water reactions and dry media reactions.\n\nBioengineering is also seen as a promising technique for achieving green chemistry goals. A number of important process chemicals can be synthesized in engineered organisms, such as shikimate, a Tamiflu precursor which is fermented by Roche in bacteria.

Wow... that's a question that could be answered on many different levels, and you're optimistic as hell to think you can get a "real" answer here. Basically, an enzyme provides a micro-enviroment that is very conducive to the formation of an intermediate form that leads from the substrate to the product. Another way of saying this is that an enzyme, like any other catalyst, lowers the activation energy of a reaction.\n\nBut seriously, dude. You're asking for a course in biochemistry here. Try Stryer, or any other classic biochem textbook, for a more thorough answer.
