Abstract
Meningkatnya konsumsi bahan bakar fosil di tiap tahunnya menyebabkan ketersediaannya semakin berkurang. Oleh karena itu, dibutuhkan pengembangan sumber energi terbarukan sebagai pengganti bahan bakar fosil. Salah satu sumber energi alternatif yang potensial adalah biofuel. Penelitian ini bertujuan untuk mempelajari pengaruh pembuatan katalis Ni-Fe/HZSM-5 dengan metode impregnasi mengetahui pengaruh % loading Ni-Fe pada HZSM-5 terhadap karakteristik katalis, mengetahui pengaruh penambahan katalis Ni-Fe/HZSM-5 dan temperatur reaksi terhadap yield biofuel melalui proses hydrocracking berbasis minyak kelapa. Alur dari penelitian ini meliputi pembuatan katalis Ni-Fe/HZSM-5 dengan metode dry impregnation lalu proses hydrocracking minyak kelapa. Produk yang dihasilkan selanjutnya dianalisa dengan menggunakan GC-MS (Gas Chromatography Mass Spectrophotometry). Dalam penelitian ini memiliki variable tetap dan variable bebas. Variable tetap meliputi bahan baku, jenis katalis, massa katalis (2 gram) dan jumlah bahan baku (200 ml). Sedangkan variable bebas meliputi suhu reaksi pada proses hydrocracking ini, yaitu 300, 325, 350,375 dan 400C. Dari modifikasi katalis Ni-Fe/HZSM-5 didapatkan penurunan nilai surface area pada katalis Ni-Fe/HZSM-5 loading 10% ratio 1:1 sebesar 312,909 m2/g. Yield gas oil pada proses pembuatan biofuel mencapai nilai terbesar 38,6% pada suhu 375C dengan menggunakan katalis Ni-Fe/HZSM-5 10% (1:1). Komposisi biofuel yang dihasilkan terdiri dari senyawa n-paraffin seperti dodekana, tridekana, heptadekana, pentadekana. Yield biofuel meningkat seiring meningkatnya suhu reaksi pada hydrocracking dari 350oC sampai 400oC.

The increasing consumption of fossil fuels in each year cause its availability so rare. Therefore, required the development of renewable energy sources as a substitute for fossil fuels. One source of alternative energy potential is biofuel. This research aims to study the influence of catalyst making Ni-Fe/HZSM-5 by method of impregnation know how% Ni-Fe loading on HZSM-5 catalysts, knowing the characteristics against the influence of the addition of a catalyst of Ni-Fe/HZSM-5 and the temperature of the reaction to yield-based hydrocracking process biofuel coconut oil. The plot of this research include the manufacture of catalysts of Ni-Fe/HZSM-5 by method of dry impregnation process of hydrocracking then coconut oil. The resulting product is subsequently analyzed using GC-MS (Gas Chromatography Mass Spectrophotometry). In this research have fixed and variable variables. Fixed variables include raw materials, type of catalyst, catalyst mass (2 g) and the amount of raw materials (200 ml). While the free variables include temperature reaction process of hydrocracking, i.e. 300, 325, 350.375 and 400°C. Catalytic modification of Ni-Fe/HZSM-5 brings about a decrease the value of the surface area of the catalyst in Ni-Fe/HZSM-5 loading the 10% ratio 1:1 of 312.909 m2/g. gas oil Yield in the process of making biofuels reached 38.6% on the largest temperature 375°C using a catalyst of Ni-Fe/HZSM-5 10% (1:1). The resulting biofuel composition comprising n-paraffin compounds such as dodekana, tridekana, heptadekana, pentadekana. The biofuel yield increase over the increasing temperature of the reaction on hydrocracking of 350°C until 400°C.
