Abstract

Sumber energi alternatif terbarukan sangat diperlukan pada masa kini, sebab penggunaan sumber energi fosil tidak dapat menjadi andalan untuk masa depan. Salah satu sumber energi alternatif yang menjanjikan adalah biofuel. Penelitian ini bertujuan untuk mempelajari cara pembuatan katalis Zn-Mo/HZSM-5 dengan menggunakan metode incipient wetnes impregnation, mengetahui pengaruh perbandingan Zn-Mo yang di impregnasikan pada HZSM-5 terhadap aktivitas katalis, pengaruh % loading Zn-Mo terhadap katalis total serta pengaruh suhu reaksi yang digunakan terhadap yield biofuel dengan proses hydrocracking minyak biji kapuk randu. Variabel yang digunakan adalah suhu reaksi hydrocracking (300, 325, 350, 375, 400), loading Zn-Mo terhadap katalis total (5% dan 10%) serta perbandingan logam Zn dan Mo (1:1 dan 1:2). Volume minyak biji kapuk randu yang digunakan adalah 200 mL dengan katalis sebanyak 1 gram. Adapun tahap penelitiannya terdiri dari 3 tahap, yaitu (1) pembuatan katalis Zn-Mo/HZSM-5, (2) karakterisasi katalis dan (3) proses hydrocracking minyak biji kapuk randu. Berdasarkan analisa yang telah dilakukan didapatkan nilai yield gas oil dan kerosene terbanyak pada variabel Zn-Mo/HZSM-5 10% 1:1 pada suhu hydrocracking 400°C sebesar 30,138% dan 11,127%. Untuk yield gasoline pada variabel Zn-Mo/HZSM-5 1:1 5% sebesar 1,237% pada suhu hydrocracking 400°C. ========================================================================================= The renewable energy sources are necessary for now, because the using of fossil energy sources is no longer preferred for the future. One of the other promising alternatives is biofuel. The aims of this study is to learn how to manufacture a Zn-Mo/ HZSM-5 catalyst by using wetnes incipient impregnation method, studied the effect of Zn-Mo ratio is impregnated on HZSM-5 to the total catalyst used in the production of biofuels with hydrocracking process, the effect of % Zn-Mo loading of the total catalyst and the effect of temperature reaction used in the biofuel yield from hydrocracking process of kapook seed oil. The variables used were temperature of hydrocracking reactions (300, 325, 350, 375, 400), Zn-Mo loading of the catalyst (5% and 10%), and the ratio of total metal Zn:Mo (1:1 and 1:2). We used 200 mL of kapook seed oil with 1 gram catalyst. This research have 3 step, (1) catalyst modification, (2) catalyst analysis, and (3) hidrocracking process of kapook seed oil. The final result of this experiment given values of yield. The biggest yield of gas oil is 30,138% using variable Zn-Mo/HZSM-5 1:1 10% at temperature of hydrocracking is 400°C. Meanwhile, the most optimum yield of kerosene is 11,127% using variable Zn-Mo/HZSM-5 1:1 10% at temperature of hydrocracking is 400°C and for yield of gasoline is 1,273% using variable Zn-Mo/HZSM-5 1:1 5% at temperature of hydrocracking is 400°C.
