The development of ammonia industry has lead to an increase in the needs of catalysts for many of its processing units; one of which is the CuO/ZnO/Al2O3 catalyst for the Low Temperature Shift Converter (LTSC). As of right now, our country catalysts need is supplied from foreign countries with relatively high price. In that matter, there comes a need to be able to produce our own catalyst in Indonesia to fulfill national-wide need of catalysts, especially CuO/ZnO/Al2O3 catalysts.<p> <br /> <br /> <br /> This research is conducted in order to find a procedure to make commercial quality CuO/ZnO/Al2O3 catalysts which is reproducible in a much larger scale. To achieve that purpose, this research follows the procedure which has been patented by Zhao, et al. (US Patent no. 6,689,713) with certain modification and complemented with reports from previous researches. The method to make the catalyst is by coprecipitation method with cupric salt, zinc salt, and alumina salt in aqueous form as the main ingredients, and malonic acid, oxalic acid, and sodium carbonate as the precipitant.<p> <br /> <br /> <br /> The research could be divided into three main steps as follow: the making of catalyst, catalyst characterization, and catalyst activity test. Characterization of catalyst surface area is determined using BET method, while the catalyst cristalinity is determined using X-Ray Diffraction (XRD) method. Catalyst activity is tested on a fixed bed reactor operating at 165-170 °C and atmospheric pressure, with the CO conversion as the parameter for catalyst activity.<p> <br /> <br /> <br /> The results show that catalysts made by the second procedure (Zhao et.al modification), e.g. TRK ZO-4, has high CuO cristalinity degree (587%) compared to the commercial catalyst’s CuO cristalinity (100%) as the basis. TRK ZO-4-1 catalyst's activity ranges from 71,2% to 80,6%; almost as high as commercial catalyst’s activity which ranges from 89,9% to 91,4%.
