| Abstract | Methyl tert-butyl ether(MTBE) is widely used as gasoline additive. Surface waters in China were polluted by MTBE with different degrees. MTBE was found to be one of the most resistant towards molecular ozone attack and difficult to be degraded by microbe. In this study, experiments were carried out to investigate the removal efficiency of MTBE by catalytic ozonation in the presence of two kinds of catalysts within a continuous reactor at different flow rates. The decomposition rate of ozone, the adsorption property of MTBE on the two kinds of catalysts and the oxidation rate of MTBE were discussed with different flow rates and initial concentration of ozone. The results indicated that the presence of iron hydroxide (FeOOH) accelerated ozone decomposition, with an ozone decomposition rate of 89.6 percents. The decomposition rate of ozone on CeO2 has a maximum value with the increase of flow rates. The adsorption capacity of MTBE on two kinds of catalysts was very limited. The oxidation rate of MTBE catalyzed by FeOOH/zeolite reached 40 percents and increased as the increase of the ozone concentration. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
