Abstract

Catalysts have an essential role in chemical processes because they can control reactions and produce the desired product. In general, catalysts function to speed up chemical reactions that can take place by lowering the activation energy. By decreasing the activation energy, the minimum energy required for the collision is reduced so that the reaction can occur faster. Selection of the suitable material to be used as a catalyst is an effort that must be made to achieve a successful process and obtain cost efficiency. The choice of material as metal and support was the aim of this research. Aluminum (Al) was the material chosen as metal and γ-Al2O as the support. The method used in the synthesis of this catalyst was dry impregnation. It is hoped that more metal will stick to the support. In this study, catalyst synthesis was carried out with two variations of treatment. The first treatment was using Al as metal and γ-Al2O3 as the support. The second treatment did not use metal only γ-Al2O3 as the support. The resulting material was characterized by XRD analysis. The analysis found that in the diffractogram pattern of Al /γ-Al2O3, the peaks appeared at 2θ = 37o; 46o and 67o. The impregnation process went well. Aluminum was evenly distributed (sticks) to the pore surface of the support and entered the poresKeywords: Catalyst, metal-support, Al/γ-Al2O3, dry impregnation, XRD

Abstract

Metal supported catalysts are used in many catalytic cracking processes. Experiments have shown that the increasing of metal loaded within the catalyst support may affected the increasing of cracking process conversion and selectivity. Therefore, a fundamental understanding of increasing the metal loaded is needed. In this study, Zinc on Alumina supported catalyst was prepared using the dry and wet impregnation methods to obtain the best amount of Zn metal content in Al2O3 as catalyst support with good characteristics for catalytic cracking. The prepared precursor solution in wet impregnation method was varied in concentration. While the dry impregnation method was varied in drying temperature. The Atomic Absorption Spectroscopy test results the metal content of Zn on the variation of precursor solution concentration on 0,5 M; 2,5 M; 4,5 M  are 1,06%; 9,65%; 15,91% and in the variation of the drying temperature at 25ºC, 50ºC, and 80ºC respectively are 18,32%; 12,48%; and 39,07%. Characteristics analysis through X-Ray Diffraction, Brunauer-Emmet-Teller, and Scanning Electron Microscopy tests have also been carried out on samples with the highest metal content of 39,07% and samples with the lowest metal content of 1,06%.
