Abstract

Besides the second generation bio fuels the bio gas oil, which is a high iso-paraffin containing fuel in the boiling range of the Diesel gasoil could be produced by the catalytic hydrogenation of different triglycerides. In this paper to improve the cold flow properties the isomerization of a normal paraffin rich mixture which was produced by the catalytic hydrogenation of slaughter house’s wastes lard was investigated over a Pt/SAPO-11 catalyst at the temperature of 320–380 °C, pressure of 30–60 bar, space velocity of 1.0–3.0 h-1 and H2/feedsock volume ratio of 400 Nm3/m3. At the favourable process parameters excellent Diesel fuel blending components (cetane number: 76–88; cold filter plugging point: between -7 and-13) were obtained, which were practically free of heteroatoms and had high isoparaffin content.
