چكيده لاتين :
Fe/Cu/K catalyst was prepared by copercipitation technique and was added to HZSA1-5 catalysts and then, mixed thoroughly with binders like Silica and Alumina and shaped to cylinders. TPR and XRD techniques were used to charactrize catalysts. Catalyst acidity was measured using frontal chromatography ammonium absorption. Activity .study was carried out in a fixed bed stainless steel reactor using following conditions: temperature ?90°(
Pressure 17bur; H2/CO=1.11; GHSV=3.07 nl(g.Fe.hi/. Results show that Alumina hinder decreases Cs selectivity, but aromatics and octane number increase with silica hinder.
