  Некоторые тезисы из работы по теме SOCIETAL IMPACT OF CATALYTIC SCIENCE AND TECHNOLOGY
  Annotation: catalysts play a vital role in providing society with fuels, commodity and fi-ne chemicals, pharmaceuticals and means for protecting the environment. To be useful, a good catalyst must have a high turnover frequency (activity), produce the right kind of product (selectivity), and have a long life (durability), all at an acceptable cost. Research in the field of catalysis provides the tools and understanding required to facilitate and accelerate the development of im-proved catalysts and to open opportunities for the discovery of new catalytic processes.
  
  SOCIETAL IMPACT OF CATALYTIC SCIENCE AND TECHNLOGY
  
  The chemical industry is one of the largest of all U.S. industries, with sales in 1990 of $292 billion and employment of 1.1 million. The United States now exports chemical products amounting to almost twice the value of those that it imports. Between 1930 and the early 1980s, 63 major new products and 34 process innovations were introduced by the chemical industry. More than 60% of the products and 90% of the processes were based on catalysis. Catalysis also lies at the heart of the petroleum refining industry, which had sales in 1990 of $140 billion. Clear-ly then, catalysis is critical of the largest industries in sales in the United States; catalysis is also a vital component of a number of the national critical technologies identified recently by the Na-tional Critical Technologies Panel.
