Catalysts for chemical, petrochemical, and petroleum refining processes constitute a significant business in the United States. BCC estimates total merchant sales of these products in the U.S. in 2010 at about $4.1 billion. The total U.S. market value is forecast to increase at a compound annual growth rate (CAGR) of about 2.5% to reach more than $4.6 billion by 2015.For all types of chemical catalysts, we estimate a total 2010 market of almost $2.7 billion, growing at a compound annual growth rate (CAGR) of about 2.5% to more than $3 billion in 2015. Polymerization is the largest chemical catalyst segment with a market of about $1.3 billion and a slightly higher CAGR.Petroleum refining catalysts are a smaller market at $1.4 billion in sales in 2010, but also are predicted to grow at about a 2.5% compound annual growth rate (CAGR) to more than $1.6 billion in 2015. Growth will be spurred by increasing demand for reformulated and other less-polluting gasolines, plus new regulations calling for drastic reductions in sulfur content in gasoline and diesel fuel.INTRODUCTIONSTUDY GOALS AND OBJECTIVESCatalysts and the products made with them are all around us, even though most people know neither what a catalyst is nor what they do.
