Preparation of biodiesel from RBD palm oil via single step transesterification process with the aid of ultrasonic irradiation and (NaOh) as catalyst

The world is increasingly accepting the fact that conventional sources of fuel and energy are being rapidly depleted and cannot be renewed. One possible alternative to fossil fuel is biodiesel, biodiesel defined as “a substitute for, or an additive to Diesel fuel that is derived from the oils and fa...
