Investigation the Effect of Oxygenic Compounds on the Isomerization of Bioparaffins Over Pt/SAPO-11

The production of gas oil blending components which a new application of the Pt/SAPO-11 is introduced, while the effect of oxygenic compounds on the isomerization of paraffin mixtures is highlighted. The experiments were carried out on 0.5% Pt/SAPO-11 catalyst at 300-380 degrees C, 30-80 bar, liquid hourly space velocity = 0.75-2.0 h(-1) and H-2/hydrocarbon ratio = 400 Nm(3)/m(3), while 0.25-5.0% oleic acid was added to the feedstock. At the favourable operational parameters the isoparaffins concentration of the products (cetane number: 78-86, cold filter plugging point: between -19 and -10 degrees C) reached 65-72%, if the oleic acid content of the feedstock was lower than 0.5%. These isomer contents were significantly decreased by increasing the oleic acid content of the feedstock.
