PP-27THE BLENDING OF SECOND – GENERATION BIO-GASOILWITH FOSSIL DIESEL: EFFECT ON PETROLEUM-DERIVEDFUEL QUALITYKirichenko E.N., Dundich V.O., Bukhtiyarova G.A., Yakovlev V.A.<strong>Boreskov</strong> <strong>Institute</strong> <strong>of</strong> <strong>Catalysis</strong> <strong>SB</strong> <strong>RAS</strong>, <strong>Novosibirsk</strong>, <strong>Russia</strong>evgenia@catalysis.ruThe blending <strong>of</strong> bi<strong>of</strong>uels in the diesel pool has become more and more importantin the past years due to several reasons: depletion <strong>of</strong> crude oil resources,environmental protection (avoiding acid rains and greenhouse effect, etc.). One <strong>of</strong>the problem arising is to introduce a large quantity <strong>of</strong> renewable fuel into the dieselfuel market without negative impact on fuel properties, affecting engine performanceand pollutant emissions. Bio-gasoil can be produced by hydroprocessing <strong>of</strong>vegetable oil with high-cetane alkanes producing [Simacek, 456].The aim <strong>of</strong> this topic is to investigate the effect <strong>of</strong> the second generation Biogasoilblending (from 5 to 50 vol. %) on the properties <strong>of</strong> the fossil diesel fuel. Thebio-gasoil used in this study was produced by hydroprocessing <strong>of</strong> rapeseed oil overNi-based catalyst in the down-flow reactor at the 6.0 MPa H 2 , LHSV=2 h -1 , H 2 /oil =300 and 350°C [1]. The samples <strong>of</strong> hydrotreated SRGO with 12 or 70 ppm sulfur aswell as the hydrotreated mixture <strong>of</strong> SRGO/LCO were used as fossil derived dieselfuel.The influence <strong>of</strong> the biodiesel addition on the boiling range distribution, specificgravity, cetane number, sulfur, nitrogen and aromatic compounds contents in thediesel fuel was considered. It was found, that parameters <strong>of</strong> blended fuel were similarto or better than those <strong>of</strong> original fossil fuel. Especially noticeable improvement incetane number, specific gravity and decrease <strong>of</strong> polycyclic aromatic compoundscontent were achieved when the bio-gasoil was added to the diesel fuel producedfrom the SRGO/LCO mixture. Such properties as excellent stability <strong>of</strong> the prepareblends and low solubility <strong>of</strong> water in them allow to use existing logistic system. So,the properties listed above open the wide perspectives for use the second generationbio-gasoil as blending component <strong>of</strong> diesel fuel.[1]. V.A.
