Preparation and Characterization of solid base Cat.TS-7 from natural Syrian zeolite TS-7
Abstract
Solid base TS-7 has been prepared from Syrian natural zeolite. Natural zeolite was treated with hydrochloric acid 10%wt for 24h at 20oC. The product was filtered to remove the silica precipitate. Ammonium hydroxide solution was added to the filtrate until it forms a gel of dissolved metal hydroxide. A certain amount of cetyl trimethyl ammonium bromide was added, and the product was placed in thermal autoclave, and the system was heated at 135oC for 8h. after the heating process the autoclave was cooled to the room temperature, and the product was filtered and washed with distilled water and dried at 110oC for 24h and calcined at 750oC for 4h. The resulted catalyst Cat.TS-7 was characterized by TG-DTA, FTTR, XRD and TPD methods. The results showed that the Cat.TS-7 consist of two crystalline phases α-Fe2O3 and ɣ-Al2O3 mainly. The amount of strong basic centers of Cat.TS-7 was 0.282 m.mol/g. the performance of Cat.TS-7 was tested in the biodiesel reaction and the yield of the reaction was 93.1%.
