The Effect of Metal Impregnation Of Fe Cu And Co on Surface Area of ZSM-5 Catalyst Analyzed Using Surface Area Analyzer (AAS)
Abstrak
ZSM-5 is a heterogeneous catalyst commonly used for petroleum cracking reactions and gas conversion processes ZSM-5 has a pore size of 0.54 nm × 0.56 nm with a surface area of 306.178 m2/g. To improve the performance of the ZSM-5 catalyst, it is necessary to impregnate it so that the surface area of the catalyst becomes smaller. One of the impregnation methods used is wet impregnation with the added metal of 2.5% wt, then characterized by using a Surface Area Analyzer (SAA). The results of the analysis showed that the surface area of the ZSM-5 catalyst impregnated with Fe, Cu, and Co, was 291,853m2/g, 302,390m2/g, and 291,504m2/g, respectively. The diameter of the pores of the ZSM-5 catalyst impregnated with Fe, Cu, and Co, respectively were 3.3896nm, 3.2688nm, and 3.2790nm, and the total volume of the pores of the ZSM-5 catalyst impregnated with Fe, Cu and Co metals, respectively, are 0.24732 cc/g, 0.24712cc/g, and 0.23896 cc/g, respectively. Therefore, the addition of Fe, Cu, and Co metals on the surface of the ZSM-5 catalyst will reduce the surface area of the catalyst, reduce the total pore volume and reduce the diameter of the pores of the ZSM-5 catalyst.
