In this study, an attempt has been made for the conversion of the bio-oil into the transport fuel. The bio-oil, in normal condition, cannot be blended with the commercial diesel; hence an experimental investigation has been conducted to overcome the blending complexity of diesel with bio-oil. IBP < 140 degrees C (Initial Boiling Point) fraction of the bio-oil has been made by Hempel distillation for separating polar compounds from the bio-oil. Different blending ratio of lighter fraction of the bio-oil (IBP < 140 degrees) with diesel has been made to seeing their compatibility. After thorough investigation, it is observed that 10% blend is meeting all the specifications of the commercial diesel. (C) 2012 Elsevier Ltd. All rights reserved.
