Permintaan produk minyak bumi seperti petrol and disel meningkat dari tahun ke tahun. Banyak negare menggunakan diperbaharui bahan organic seperti minyak sayur untuk mengeluarkan biofuel untuk menyelesaikan masalah ini dan masalah persekitaran. Dalam kajian ini, penghasilan cecair biofuel daripada hydroprocessing kelapa sawit mentah telah dipelajari. Kesan daripada reaksi parameters seperti jenis mangkin, alumina size pori dan suhu reaksi telah diselidiki. Hydroprocessing reaksi telah dilaksanakan di dalam sebuah reaktor batch dalam kisaran suhu dari 350°C ke 390°C, dalam tekanan 500psi, kelajuan penguli 350rpm dan 1 jam untuk waktu retensi. Dalam kajian, CoMo/Al2O3 pemangkin memberikan produk cair hasil yang tertinggi. Aktiviti mangkin menurun dalam urutan CoMo/Al2O3 > Mo/Al2O3 > NiMo/Al2O3. Alumina dengan saiz liang yang berbeza seperti 3.6 nm, 9.0nm and 16.1 nm telah diuji. Di antara mereka bertiga, alumina terbesar saiz pori (16.1 nm) memberikan penukaran tertinggi produk cair dalam percubaan. Reaksi suhu juga dijumpai mempengaruhi reaksi hydroprocessing minyak sawit mentah.

The demand for petroleum products such as gasoline and diesel is increasing over the years. Many countries use the renewable organic material such as vegetable oils to produce biofuels to cope with this problem and the environmental problems. In this research, the productions of liquid biofuels from hydroprocessing of crude palm oil were studied. The effects of reaction parameters such as types of catalyst, alumina pore size and reaction temperature were investigated. The hydroprocessing reactions were carried out in a batch reactor at the temperature range from 350°C to 390°C, at pressure of 500 psi, stirrer speed 350 rpm and 1 hour retention time. In the study, the CoMo/Al2O3 catalyst gave the highest liquid products yield. The activity of the catalyst decreased in the order CoMo/Al2O3 > Mo/Al2O3 > NiMo/Al2O3. Alumina with different pore size which was 3.6 nm, 9.0nm and 16.1 nm were tested. Among three of them, the largest alumina pore size (16.1 nm) gave the highest the conversion of liquid product in the experiment. The reaction temperature is also found to affect the hydroprocessing reaction of crude palm oil.
