| 1 | Synthesis of Modified β-Zeolite Under Microwave Irradiation and Its Use on Etherification显示文摘zeolite was synthesized by using tetraethyl ammonium hydroxide as the template reagent andmicrowave radiation as the heat source. The effect of the sol composition and the radiation temperature onzeolite crystallinity was investigated. The zeolite was tested and compared with the commercial product, whichwas produced by conventional hydrothermal synthesis method. The physico-chemical properties of the syn-thesized samples, the specific surface area of the samples synthesized under microwave irradiation and porevolume measured by X-ray diffraction apparatus, were better than the conventional samples. The etherificationexperiment on FCC light naphtha in the presence of transition metals modified Hβ-zeolite, which was synthe-sized firstly under microwave irradiation, was studied in a fixed-bed reactor. The effect of catalyst preparationconditions on its activity, stability and the effect of reaction temperature, methanol/tertiary-carbon olefin molarratio and liquid hourly space velocity on the etherification reaction were discussed. The experimental resultsshowed that the different metals modified Hβ-zeolite had different etherification performances. And theconversion of tertiary carbon-olefins of the molybdenum modified Hβzeolite, which was loaded at a concen-tration of 3 percents, was higher than that on 6.0 percent of Hβzeolite. The modified Hβzeolite catalystspossessed favorable prospects for its higher stability. | Ma Jun1,2 Wang Haiyan2 Hu Tingfang2 TianYanwen1 Zhou Tong3 Qin Zhiwei3(1 Department of Material and Metallurgy, Northeastern University, Shenyang 110004 2 College of Petrochemical Engineering, Liaoning University of Petroleum & Chemical Technology,Fushun 113001 3 PetroChina Fushun Ethylene Chemical Company Limited, Fushun 113004) | 2004 | China Petroleum Processing & Petrochemical Technology2004，6，4： | 0 |
