Abstract

Natural gas has an important role in the process of the chemical industry, one of which is in the petrochemical industry. It's just that gas originating from nature still contains H2S is corrosive and risk poisoning the catalyst or damage other tools so that the presence of H2S is avoided before entering the process. One of the studies developed to reduce H2S levels is by using a catalyst. The catalyst is more beneficial because of lower energy consumption and converts to solid sulfur. Making zeolites can be done by modifying zeolites with metals which have the potential to be able to increase the absorption of H2S in the space temperature. Therefore, in this research an attempt was made to make a catalyst made from natural zeolites combined with metal compounds, CaO which is more economical. The catalyst preparation process is carried out by the impregnation method, in which there are 3 variations of the catalyst based on a Natural Zeolite: CaO ratio, 5: 1, 7.5: 1, and 10: 1. Furthermore, the catalyst that has been successfully made, characterization tests are carried out using SEM and XRD analysis. SEM analysis results show differences in particle morphology between catalyst samples. The analysis shows that the impregnation process was successful. Furthermore, the catalyst which has been successfully synthesized, is tested by various process variables. The catalyst mass in each variation of the composition used also varies in mass, which is 40 gr, 50 gr, 60 gr, 70 gr, and 80 gr. In the process, variations in the catalyst feed flow rate vary, namely 5, 10, 30, 50, and 80 Liters / minute. Therefore, it is known that the composition of Zeolite and CaO 5,0 : 1,0 is the best composition and produces the highest conversion. The lower the flow rate and the higher the catalyst mass value, the better the H2S dissociation process.
