 Abstract

Sebuah metode untuk memproduksi green diesel sebagai bahan bakar terbarukan dengan menggunakan hydrotreating katalitik pada minyak nabati telah dilakukan. Terdapat tiga jalur reaksi utama yaitu decarbonylation (DCO), decarboxylation (DCO2), and hydrodeoxygenation (HDO). Pada penelitian ini dilakukan menggunakan umpan minyak sawit (CPO) dari Indonesia pada reaktor continuous-flow trickle-bed skala pilot plant dengan menggunakan katalis komersial hydrotreating NiMoP/γ-Al2O3. Suhu dan tekanan hydrotreating merupakan parameter operasi yang paling dominan mempengaruhi kinerja katalis. Variasi parameter kondisi operasi hydrotreating seperti temperatur 285°C-390°C dan tekanan H2 20 bar-70 bar untuk mendapatkan recovery, konversi, yield produk dan kontribusi pada reaksi HDO dan DCO/DCO2 telah diselidiki untuk mendapatkan kondisi optimal hydrotreating. Terjadi kompetisi antara reaksi HDO dan DCO/DCO2 untuk setiap kondisi operasi. Kontribusi pada reaksi HDO meningkat pada temperatur rendah dan tekanan tinggi. Sedangkan kontribusi pada reaksi DCO/DCO2 meningkat pada temperatur tinggi. Pada penelitian ini dihasilkan kondisi optimal yaitu pada temperatur 330°C-350°C, tekanan 30 bar-50 bar, LHSV 1-hr dan rasio H2/minyak 1000 Nm3/m3. Produk yang dihasilkan telah sesuai dengan spesifikasi produk pengganti solar konvensional.

A method for producing green diesel as a renewable fuel using catalytic hydrotreating on vegetable oils has been done. There are three main decarbonylation reaction pathway (DCO), decarboxylation (DCO2), and hydrodeoxygenation (HDO). In this study conducted using bait palm oil (CPO) from Indonesia on a continuous-flow reactor trickle-bed pilot plant scale using a commercial hydrotreating catalyst NiMoP/γ-Al2O3. Temperature and pressure hydrotreating the is most dominant operating parameter affects the performance of the catalyst. Variation dominant hydrotreating parameters such as temperature 285°C - 390°C and H2 pressure of 20 bar - 70 bar to obtain a recovery, conversion, product yields and contribute to the HDO reaction and the DCO/DCO2 were investigated to find the optimal hydrotreating conditions. On the results of this study has occurred competition between HDO reaction and the DCO/DCO2 reaction for each operating condition. Contribute to the HDO reaction increases at low temperatures and high pressure. While contributing to the reaction DCO/DCO2 increased at higher temperatures. In this study produced optimal conditions at a temperature of 330°C - 350°C, a pressure of 30 bar - 50 bar, LHSV 1-hr and a ratio of H2/oil 1000 Nm3/m3. Products produced in same specifications with conventional diesel replacement.
