Abstract
Penelitian ini memiliki tujuan umum yaitu mempelajari proses pembuatan katalis Ni-Mo/H-ZSM-5 menggunakan metode incipient wetness impregnation. Mempelajari pengaruh % loading logam Ni dan Mo yang diimpregnaskan pada katalis H-ZSM-5 dan pengaruh suhu reaksi dalam proses catalytic hydrocracking minyak biji kapuk randu (Ceiba pentandra) terhadap nilai yield dan konversi yang dihasilkan pada reaktor pressure batch. Selain itu, penelitian ini juga mencari model kinetika reaksi proses catalytic hydrocracking pada reaktor pressure batch.
Pada tahap pembuatan katalis Ni-Mo/H-ZSM-5 terjadi penurunan luas permukaan katalis seperti yang ditunjukkan oleh hasil analisa BET (Brunauer-Emmett-Teller) untuk katalis Ni-Mo/H-ZSM-5 dengan % loading 10% dan rasio (1:3) yaitu sebesar 213.6600 m2/g. Difraktogram yang dihasilkan dari analisa XRD (X-Ray Diffraction) menunjukkan puncak - puncak identik JCPDS dari penyangga H-ZSM-5, logam Ni dan logam Mo. Hal ini menunjukkan bahwa logam Ni dan Mo berhasil terimpregnasi ke dalam penyangga katalis H-ZSM-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 dan konversi terbaik diperoleh pada penggunaan katalis Ni-Mo/H-ZSM-5 dengan % loading 10% dan rasio (1:3) yaitu yield kerosene 26.3348%, yield gasoil 43.6911% dan nilai konversi sebesar 88.64%. Persamaan kinetika reaksi untuk reaksi catalytic hydrocracking minyak biji kapuk randu menggunakan katalis Ni-Mo/H-ZSM-5 pada reaktor pressure batch dapat dirumuskan -rA=(13,30×10)^(3e^93.16/8.314T)CA ================== This research has a general purpose of studying the process of produce Ni-Mo/H-ZSM-5 catalyst using incipient wetness impregnation method. Studied the effect of %loading of Ni 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 and conversion values that produced in pressure batch reactor. In addition, this study also determine the reaction kinetic model of catalytic hydrocracking process in pressure batch reactor.
At the Ni-Mo/H-ZSM-5 catalyst preparation step, there was decreasing of catalyst surface area that determined by BET (Brunauer-Emmett-Teller) analysis for Ni-Mo/H-ZSM-5 catalysts with 10% loading and ratio (1: 3) that is equal to 213.6600 m2 / g. the XRD (X-Ray Diffraction) diffractogram showed the identical peaks of JCPDS from H-ZSM-5, Ni and Mo metals. This indicated that Ni and Mo metals were successfully impregnated into the H-ZSM-5 catalyst support.
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 yield and conversion values were obtained on the use of Ni-Mo / H-ZSM-5 catalyst with 10% loading% and ratio (1: 3) i.e. 26.3348% of kerosene yield, 43.6911% of gasoil yield and conversion value 88.64%. The reaction kinetics equation for catalytic hydrocracking reaction of kapuk randu seed oil using Ni-Mo/H-ZSM-5 catalyst at pressure batch reactor is well-defined by -rA=(13,30×10)^(3e^93.16/8.314T)CA
