SYNTHESIS OF NOVEL MICRO-MESOPOROUS COMPOSITE AND ITS APPLICATION IN FCC GASOLINE HYDRO-UPGRADING

摘要

In recent decades, new technologies to produce clean fuels are developed increasingly and are paid more attentions to meet the stringent environmental legislation in the world. Some related processes such as adsorption, extraction, oxidation, alkylation and bioprocessing are under exploration. However, hydrogenation technology still appears to be the preferred process to obtain ultra clean fuels in a large scale. Compared with the traditional Al2O3 supported hydrotreating catalysts, novel type catalysts with suitable physico-chemical property, high activity, long-life and good economy are extremely desired. Since Corma and his group introduced the ordered micro-mesoporous materials in 1998, more efforts have been devoted to the design and development of molecular sieves with micro-mesoporous structure over the past years. In this work, Beta-MCM-48 composite was optimally synthesized and was applied to be the catalyst in the hydro-upgrading of FCC gasoline.
