Biodiesel is one of an environmentally friendly alternative fuels. This study aimed to synthesize biodiesel from waste frying oil by the two step catalytic process, esterification of free fatty acids using sulfuric acid ...

CaO is a basic catalyst which is frequently used for the synthesis of biodiesel. The development of catalyst especially CaO has become attractive topic for research in order to obtain good catalytic activity so that biodiesel ...

One source of vegetable oil that hasn’t been used and generated from sortation process in palm oil mill is off-grade oil palm fruit. Availability of off-grade oil palm fruit is about 7-10% for a Palm Oil Mill with capacity ...

CaO catalyst is a heterogeneous catalyst used in biodiesel synthesis. Modification of the CaO catalyst with porous materials such as silica (SiO2) was carried out to increase its catalytic activity. The aim of this ...

Energy reserves derived from oil and natural gas have a limited amount, so alternative renewable energy such as biodiesel is needed. Biodiesel can be derived from vegetable oil or animal fat. Oil from plants is more ...

Biodiesel is a renewable alternative fuel that is derived from the transesterification of vegetable oil or animal fat and alcohol using a catalyst. In this research, transesterification of oil into biodiesel was conducted ...

Biodiesel is one of alternative fuels which renewable and derived from vegetable oils or animal fats, so it is usemore environmentally friendly. In this study biodiesel was synthesized through transesterification reaction ...

CaO catalyst is a heterogeneous base catalyst which has been widely used in biodiesel synthesis. Hydration-dehydration is one of the newest methods in the synthesis of CaO catalysts which is considered quite efficient ...

Fossil fuels that are not environmentally friendly and their presence is decreasing due to their increasing use has spurred researchers to produce alternative fuels from renewable and environmentally friendly sources, ...

Dog-conch snail waste can be used in the research field. Dog-conch snail shells contain carbonate compounds (CaCO3) which can be conversed to CaO through a calcination process at a temperature of 700-900 ºC. CaO is an ...
