Aromatic compound which usuallt used as raw material for coating acrilik surface, diesel fuel, and lube aditive is 2-ethylhexanol. In the future, the needs of 2-ethylhexanol is expected to increase. Actually, 2-ethylhexanol industry has been established in Indonesia, but some raw material still have to be importes from other countries, such as catalyst. Because we still have to import the catalyst, that is why development of nickel based catalyst for hydrogenation 2-ethylhexenal to 2-ethylhexanol is needed. <br /> <br /> The goal of this research is to get kinetic model of hydrogenation 2-ethylhexenal to 2-ethylhexanol over 20% Ni-Cu-K/AIP catalyst and to compare the kinetic parameter of the catalyst with comercial catalyst. Variation used in this research are variation of temperature and space velocity. Temperature used are 120oC and 130oC and space velocity is variated by reactant flow 0,5 – 0,95 mL/minute. This research is performed by using isothermal fix bed reactor. Reaction products will be analyzed using gas chromatography. <br /> <br /> The result of this research is kinetic model of hydrogenation 2-ethylhexenal to 2-ethylhexanol over nickel based catalyst can not be obtained. This phenomena is caused by deactivation process which resulted from imperfection if catalyst synthesis. Deactivation catalyst can be proven by BET test used Pore Size Analyzer Nova 3000E. The result of the test showed that the area in used-catalyst decrease from 348,084 m2/g to 107,239 m2/g.
