  3. Abstract:
  4. In the present work, Tetrahydrofuran was produced from 1,4-butanediol by catalytically dehydration of 1,4-butanediol in contact with a catalyst. Material used as catalyst were Synthesized and natural zeolites as well as alumina and silica. Synthesized zeolites were investigated in different aspect such as pore size, cation and Si/Al ratio. Results indicated that with increasing the Si/Al ratio, the activity of the zeolite used for 1, 4-butanediol dehydration step was reduced. Furthermore, it was observed that, upon the replacement of sodium with hydrogen and ammonium cations, the conversion of the 1, 4-butanediol into tetrahydrofuran was increased. It was shown zeolites possessing smaller pore sizes than the tetrahydrofuran molecule are not adequate for production of this material. Ultimately, it is shown that the ZSM-5 zeolite with NH 4+ is the most active catalyst for dehydration of 1, 4-butanediol. It is note worthy that, in all experiments, the selectivity of tetrahydrofuran remained around 100% without any noticeable change in catalyst stability
