Development of Direct Production Process of Diesel Fuel from Vegetable Oils

Abstract

A new direct production process was developed for making high quality diesel fuel from oils and fats. In this process, which was operated under atmospheric pressure by using neither methanol nor hydrogen, no glycerin was produced. The product of the present process was composed of small amount gas (CO₂, light hydrocarbons and minor amount of CO) and liquid hydrocarbons (C₁₀-C₂₀). The liquid product was composed of olefins and paraffins with straight and branched chain structure.
