the fast depletion of petroleum crude oil reserves and the serious consideration of environmental issues make the implementation of sustainable energy sources a crucial issue worldwide. biofuel derived from vegetable oils is receiving a great attention as one of the most suitable and logical alternatives of fossil fuels. therefore, the production of petroleum-like fractions from nonedible oil e...

Hydrocracking of crude palm oil (CPO) to produce biofuels was conducted over zirconium nitride supported on SiO2 (SiO2/ZrN) catalyst. SiO2/ZrN prepared by nitriding the SiO2/Zr at 600 C for 3 hrs under NH3 gas cylindrical reactor. exhibited a surface acidity 0.7132 mmol pyridine g‒1 with area 96 m2 g‒1, forming predominant mesopores EDS- mapping analysis showed that ZrN species highly distribu...

<p align="justify">The modification of natural zeolite has been conducted by dealumination and desilication using HCl NaOH treatments as a catalyst for hydrocracking used cooking oil into biogasoline. This research aimed to study the effect on activity selectivity process. A variety catalysts was prepared applying 3, 6, 9 M in produce DNZ(3-1), DNZ(3-2) DNZ(3-3), DNZ(6-1), DNZ(6-2), DNZ(6...
