Etherification Performance of Transition Metals Modified β -Zeolite Catalyst.

The etherification experiment for FCC light gasoline on transition metals modified H β zeolite was studied in a fixed-bed reactor. The effect of preparation condition of catalyst on the catalyst's activity, stability, and the effect of reaction temperature, methanol/tert-olefin molar ratio, and liquid hour space velocity on the etherification reaction were discussed. The experimental results showed that the different metals modified H β zeolite had different etherification performances. And the conversion of tertiary carbon-olefins of the molybdenum modified H β zeolite, which was loaded 3%, was higher 6.0% than the H β zeolite. The optimal reaction conditions were temperature 70–80°C, liquid hour space velocity 1.0 h -1 and methanol/tert-olefin molar ratio 1.05. The modified H β zeolite catalysts possessed favorable prospect for its higher stability. [ABSTRACT FROM AUTHOR]
