Abstract�� Ethyl tertiary butyl ether(ETBE)was synthesized from ethanol and tert-butyl alcohol catalyzed by the H�� zeolite,HY,HUSY,HZSM-5 and D-06 resin in a fixed-bed reactor.The comparison experiments were performed and the results showed the catalytic activity order of zeolite was:H�� zeolite>HY>HUSY>HZSM-5,the catalytic activity of H�� zeolite is nearly the same as that of resin.The stabilities of HY and H�� were determined and showed that H�� had better stability than HY,and H�� can be used for 175 h.
