Pada era globalisasi ini, penggunaan petroleum dan produk berasaskan petroleum semakin meningkat. Permintaan petroleum yang semakin meningkat meruncing kepada isu alam sekitar dan pembebasan gas-gas hijau yang semakin membimbangkan. Oleh sebab itu, ia adalah penting untuk mengitar semula minyak buangan atau minyak yang telah diguna. Dalam kes ini, pengitaran semula sisa minyak motor kepada minyak bahan api dipraktikkan melalui proses retakan hidro yang menggunakan pemangkin. Dalam kes ini, pelbagai pemangkin logam diuji. Logam Molybdenum memberikan konversi yang tertinggi dengan hasil bahan api yang ringan. Suhu yang berbeza juga dikaji bermula dari 375ºC, 400°C dan 425ºC. Peningkatan suhu meningkatkan lagi produk minyak yang diperlukan. Selain itu, tekanan sebanyak 500 psi, 550 psi dan 600 psi juga dikaji. Pemboleh ubah seterusnya adalah masa reaksi. Masa untuk reaksi berlaku diubah dari sejam kepada dua jam untuk memerhatikan hasil minyak yang diperoleh iaitu minyak gasoline, minyak kerosen dan diesel.

The increasing demand of high value of petroleum products and its increasing usage brings in an environmental concern due to the emission of greenhouse gases. It is more economic to recover waste oil product; in this case waste motor oil. Motor oils are derived from lube oils and it is a good start to recover these waste motor oils to be used as fuel oil. The mean or method to this would be catalytic hydrocracking. In this study, reaction parameter of catalytic hydrocracking such as type of metal loading, reaction temperature, reaction pressure and residence time are studied for a better yield of fuel oil. The hydrocracking reactions were carried out in a pressure reactor at temperature from 375°C to 425°C and the initial pressure used would be from 500 psi to 600 psi. In the experiment, alumina supported Molybdenum base catalyst was found to be best catalyst using studied catalyst. The reaction temperature was found to affect the hydrocracking reaction of palm oil. Meanwhile, the increase in the reaction pressure has significantly improved the conversion of palm oil to gasoline, kerosene and diesel.
