| Abstract: | Silicon carbide foam ceramic with 3D cross-linked reticular structure is presented to be used as catalyst carrier for reducing HC and CO pollutants in diesel exhaust with its performance and the effect of electrical heating studied.The results show that silicon carbide foam ceramic has appropriate electric conductivity and excellent thermal shock resistance,so is suitable for use as electrically heated catalyst carrier to increase the exhaust temperature,and hence improve the conversion efficiency of HC and CO in diesel exhaust at lower temperature. |
