Abstract:
In recent years, the conversion of vegetable oils and used frying oils into transportation fuels via hydroprocessing of these feedstocks is under investigation. Hydroprocessing converts the triglycerides that account almost 100% of the oils into hydrocarbons that have characteristics similar to those of automotive diesel fuel. The hydroprocessing reactions convert the triglycerides mainly to normal parafins with 16 – 20 carbon atoms per molecule. These hydrocarbons have very high cetane numbers, high stability and high heating value, but suffer from very poor cold flow properties and very poor lubricity and cannot be used as neat fuels The simplest method to use these fuels is the traditional blending used in petroleum refineries. An alternative method is to blend vegetable oils or used frying oils with conventional gasoil and use this blend as feed to hydroprocessing unit. By this technique the products of the triglycerides hydroprocessing increase the cetane number of the final product.This paper describes the detailed analysis of the fuel that was produced from the hydroprocessing of a blend consisting of 30% used frying oils and 70% heavy atmospheric gasoil according to the official EN 590 european standard. This fuel has high cetane number, but due to the use of heavy atmospheric gasoil, the final product has properties that do not meet the EN 590 standard. The fuel was fractionated and blended with low cetane number gasoil and kerosene. The results showed that some of the blends have properties very close to those described by EN 590 standard, and therefore they can be used as blending components in the diesel fuel pool.
