Treating n-butane by activated carbon and metal oxides

In order to reduce environmental pollution and regulatory issues, the adsorption of n-butane from vehicle exhaust is one of the necessary requirements. When active carbon was mixed with different proportions of metal oxides, the adsorption capacity of n-butane was markedly improved. Infrared spectroscopy data provided information on functional groups derived from activated carbon composite metal oxide indicating that one of the best adsorption capacities for n-butane was obtained by mixing 3g TiO2, 2.7g CuO, and 2.1g NaBO(3)4H(2)O with 30g activated carbon. However, more effective results were obtained by mixing 6g TiO2, 2.1g CuO, and 0.9g NaBO(3)4H(2)O with 30g activated carbon. Data suggest that these chemical complexes may be effective in lowering n-butane pollution.
