Abstract

Kinetika hidrogenasi katalitik 1-oktadekena telah dipelajari pada pengaruh temperatur reaksi. Katalis Ni/Zeolit dipreparasi melalui tahapan perlakuan asam (HF, HCl, NH₄Cl), kalsinasi dengan N₂, oksidasi dengan O₂ dan reduksi dengan H₂ serta impregnasi logam Ni (Ni(NO₃)₂.6H₂O) melalui teknik impregnasi basah dan pertukaran ion. Uji aktivitas katalis dilakukan pada reaksi hidrogenasi katalitik 1-oktadekena pada variasi temperatur yaitu 400°C, 450°C dan 550°C dengan laju alir gas H₂ yang tetap, 15 mL/menit. Hasil penelitian menunjukkan bahwa reaksi hidrogenasi katalitik senyawa 1-oktadekena pada temperatur 400°C memilki konstanta laju reaksi (k) dan energi aktivasi berturut-turut 0,0900 menit^-1 dan -46,14 kJ/mol. Laju reaksi hidrogenasi katalitik senyawa 1-oktadekena dengan katalis Ni/zeolit semakin menurun dengan meningkatnya temperatur reaksi pada rentang temperatur 400 hingga 550^oC.
