Abstract A series ofCuO over HZSM-5 catalysts were prepared by wet impregnation technique followed by dealumination using oxalic acid. The loading ofCuO over HZSM-5 was kept between 0 and 9 wt% and treated with oxalic acid. XRD, Surface area analyzer, metal trace analyzer and SEM techniques were used to characterize the catalysts. The higher yield of gasoline range hydrocarbons were obtained with the increase in weight % ofCuO over HZSM-5.Effect of run time on the hydrocarbon yields and methanol conversion was investigated. The activity of the catalyst decreased progressively with time on stream. Relatively lower coke deposition over HZSM-5 catalysts was observed compared to CuO impregnated HZSM-5 catalyst. The effect of run time was studied to investigate the effect oxalic acid treatment on catalyst stability. Top Keywords CuO/HZSM-5, Impregnation, Deactivation, Methanol Conversion.
