In chemical production, scientists experiment and life activities, catalyst display skills to the full. For example, in sulfuric acid production with five of two vanadium catalyst by nitrogen and hydrogen. Ammonia, with iron based catalyst group, improve the reaction rate. In the refinery, the catalyst is ultimately, using different catalysts that can get different quality of gasoline and kerosene. Carbon monoxide and nitric oxide in automobile exhaust harmful, using platinum as a catalyst can be quickly converted into carbon dioxide and two nitrogen harmless. Enzyme is a plant, animal and microorganism which has the catalytic ability of the protein, the chemical reactions of living organisms are almost in catalysis the role of enzymes, brewing industry, the pharmaceutical industry should be used as the catalyst. The catalytic chemical reaction does not change in the situation, the less active energy ( Activation energy of the path in a chemical reaction. And usually under this energy, molecules are not unable to complete chemical reaction, or is the need to for a long time to complete the chemical reaction. But in the catalyst molecular just less energy can complete the chemical reaction.
