Preparation of H-ZSM-5 Zeolite and its Use for preparation of Ethers

This paper describes the preparation of HZSM-5 zeolite by a laboratory way using tetra propyl ammonium bromide, sodium hydroxide, silica fiber, NaAl2O3 and NH4 NO3 to prepare at first NaZSM-5 and secondly transferring it to NH4 ZSM-5 and finally transferring it to HZSM-5. In a second part this catalysts are used for some etherification reactions.
