Abstract
Produksi industri minyak bumi nasional semakin hari semakin menurun. Sumber energi alternatif sangat diperlukan sebagai pengganti bahan bakar dengan menggunakan minyak nabati yang biasa disebut dengan biofuel. Penelitian ini memiliki tujuan umum yaitu untuk mempelajari pengaruh rasio perbandingan impregnasi pada HZSM-5, untuk mempelajari pengaruh % loading logam Zn dan Mo yang diimpregnaskan pada katalis HZSM-5 dan pengaruh suhu reaksi dalam proses catalytic hydrocracking minyak biji kapuk randu (Ceiba pentandra) terhadap nilai yield yang dihasilkan pada reaktor batch. Pada tahap pembuatan katalis Zn-Mo/HZSM-5 terjadi penurunan luas permukaan katalis seperti yang ditunjukkan oleh hasil analisa BET (Brunauer-Emmett-Teller) untuk katalis Zn-Mo/HZSM-5 dengan % loading 10% dan 5%. Difraktogram yang dihasilkan dari analisa XRD (X-Ray Diffraction) menunjukkan puncak - puncak dari penyangga HZSM-5, logam Mo, oksida logam ZnO, oksida logam MoO2. Hal ini menunjukkan bahwa impregnasi logam Zn dan Mo tidak merubah struktur kristalinitas dari HZSM-5. Katalis yang dihasilkan digunakan dalam uji aktivitas katalis melalui proses catalytic hydrocracking minyak biji kapuk randu kemudian produk yang dihasilkan dianalisa meggunakan GCMS (Gas Chromatography - Mass Spectrofotometry) untuk mengetahui kandungan senyawa hidrokarbon yang terdapat produk. Pada uji katalitik nilai yield kerosene terbaik diperoleh pada penggunaan katalis Zn-Mo/HZSM-5 dengan % loading 10% dan rasio (1:4) yaitu 38.32%, sedangkan untuk yield gasoil terbaik diperoleh pada penggunaan katalis Zn-Mo/HZSM-5 dengan % loading 10% dan rasio (1:3) yaitu 24.64%.

National petroleum industry's production is decrease daily, so Alternative energy sources really needed as a substitute
for fuel by using vegetable oils commonly referred to as biofuels. This research has a general purpose of studying the effect of ratio impregnated on H-ZSM-5, studied the effect of %loading of Zn and Mo metal that impregnated on H-ZSM-5 catalyst and the effect of reaction temperature in catalytic hydrocracking process
of kapuk (Ceiba pentandra) seed oil against the yield value that produced in batch reactor. At the Zn-Mo/H-ZSM-5 catalyst preparation step, there was decreasing of catalyst surface area that determined by BET (Brunauer-Emmett-Teller) analysis for Zn-Mo/H-ZSM-
5 catalysts with 10% loading and 5% loading. The XRD (X
-Ray Diffraction) diffractogram showed the identical
peaks from H-ZSM-5, Mo metal, ZnO metal oxide, MoO2
metal oxide. This indicated that Zn and Mo metals impregnation didn’t change the cristalinity sructure of H-ZSM-5. The obtained catalysts were used in the catalytic activity test through catalytic hydrocracking process of the kapuk randu seed oil and the
obtained products were analyzed using
GCMS (Gas Chromatography - Mass Spectrophotometry) to determine the hydrocarbon content of the product. In the catalytic hydrocracking test, the best of kerosene yield were obtained on the use of Zn-Mo / H-ZSM-5 catalyst with 10% loading% and
ratio (1: 4) i.e. 38.32%,and the best of gasoil yield were obtained on the use of Zn-Mo / H-ZSM-5 catalyst with 10% loading% and ratio (1: 3) i.e. 24.64%
