Laws and Regulations
1989 law, Act No. 89-824, established a 25% waste reduction and recycling goal; No due date for goal; no formal requirements for localities to report recycling information to state, statistics on recycling unavailable, but there has been a dramatic increase in curbside and drop off center recycling. 1990 law, Act No, 90-564 requires all state agencies, schools (K-12), and public colleges and universities to implement recycling programs.

    2. Engelhard Corp., BASF, the corporation that revolutionized the catalytic converter market. Engelhard pioneered development of the first catalytic converters, which appeared on 1975-model cars. A year later, Engelhard introduced a major innovation the modern, "three-way" catalyst, which today is capable of destroying 97% of hydrocarbons (HC), 96% of carbon monoxide (CO) and 90% of nitrogen oxides (NOx) produced by car engines.

    Design Project #3 - Kinetics - Catalytic Converter For CNG Automobile Exhaust
    Automobile exhaust contains significant amounts of air pollutants such as carbon monoxide, nitric oxide (NO), and hydrocarbons. Catalytic converters promote chemical reactions which turn these compounds into relatively harmless carbon dioxide and nitrogen. Laboratory studies have shown that the rate of reaction (from chemistry) can be written with a dependence on temperature. A simple material balance (chemistry) for NO across a differential slice (mathematics) of the converter will lead to a solution equation that gives the concentration of NO as the exhaust gas flows through the converter. The catalyst pellets are porous spheres of alumina with the costly noble metal rhodium dispersed on the surface. The design problem presented to the students was thus:
    "Design a catalytic converter that will help a CNG-powered engine meet the current U.S. federal emissions limits for NO."
    The solution equation for this problem was given to the students and was easily implemented on a spreadsheet. Unfortunately, the students were told to use the weight of the catalyst (rhodium) in the equation, instead of the weight of the combined catalyst and alumina pellet. This misunderstanding caused the design project to be much more difficult than anticipated, since acceptable solutions based on emission reduction required unreasonable quantities of expensive rhodium. The problem was further compounded when the course instructor (the first author) left town for a three-day workshop at a critical point in the design project. Ideally, the students should have focused on the following design considerations:

  • What problems occur when the engine is cold at startup? How can you solve them?
  • Is it reasonable to assume the converter behaves isothermally?
  • For the same size converter shell, how could you change the catalyst to increase the conversion of the NO? Does this create other problems?
  • Look under a car (use proper safety precautions!) and sketch out the exhaust system. Why is it arranged this way?

    George W Bush Honours Corning Scientists for Catalytic Converter Technology
    President George W. Bush today announced the winners of the 2003 National Medal of Technology, including a team of Corning Incorporated scientists for their invention of the cellular ceramic substrate. While working at Corning in the 1970s Drs. Rodney D. Bagley, Irwin M. Lachman and Ronald M. Lewis developed a totally new, economical, high-performance cellular ceramic substrate that has since set the standard for vehicular catalytic converter efficiency worldwide.
    The National Medal of Technology, the highest honor bestowed by the President of the United States on America's leading innovators, recognizes technical contributions that significantly impact commerce and advance the American standard of living.
    Since 1975, catalytic-converter-equipped vehicles have helped cut air pollution by more than 1.5 billion tons in the United States alone and 3 billion tons worldwide, according to the Manufacturers of Emission Controls Association (MECA). Virtually every automotive company in the world today relies on the basis of the Corning team's cellular ceramic technology to control exhaust emissions.
    Today's honor marks the fourth time Corning has been affiliated with the National Medal of Technology since the medal's inception in 1985. http://www.azom.com/news.asp?newsID=2547
