Low Temperature Shift Conversion (LTSC) is one of chemical processes in industries applyed to remove CO produced from steam reforming, gasification, and partial oxidation at low temperature (150260 degrees C). CO removal is conducted by water-gas shift reaction, for instance in ammonia and hydrogen plant.<p> <br /> <br /> <br /> <br /> <br /> LTSC catalyst has potency to be developed in Indonesia due to it's high demand in ammonia and hydrogen plant. This catalyst has function to accelerate water-gas shift reaction at low temperature. Therefore, this research is conducted in order to establish a synthesis procedure of Cu/ZnO/Al2O3 catalyst for LTSC which has catalytic activity equal to the commercial catalyst and can be reproduced.<p> <br /> <br /> <br /> <br /> <br /> This research consists of two main steps which are catalyst synthesis and catalytic activity test. Catalyst synthesis is conducted by dry impregantion method with Cu as active site, ZnO as promotor, and &#947;-alumina as catalyst's support. Catalytic activity is tested using fixed bed reactor which operate at 230oC and ambient pressure. The compositions of the catalyst is variated by ratio of Cu/ZnO as follows, 1 : 1; 2 : 1; 1 : 2 (molar base).<p> <br /> <br /> <br /> <br /> <br /> Cu/ZnO/Al2O3 catalyst-named as ReiKo catalyst-is capable of converting CO up to 65,06-73,21%. Inspite of it's lower conversion than commercial catalyst which is able to convert CO up to 83,98-85,10%, ReiKo catalyst has less active sites than the commercial ones. ReiKo catalyst have active sites around 8-19%-w/w, while commercial catalyst is around 30-32%-w/w. Besides, ReiKo catalyst has stability that equal to the commercial ones.
