Abstract:
The catalytic co-processing of different natural triglycerides and gas oils is a possibility to produce bio-component containing fuels. The aim of our experiments was the selection of a catalyst which is suitable for the selective isomerization of high normal paraffin containing hydrocarbon mixtures partly derived from natural triglycerides. We investigated the activity of several isomerization catalysts. In this paper the relevant results obtained on Pt/SAPO-11 which was one of the most suitable catalysts are presented. Experiments were carried out with 80 cm3 of catalyst at 300-380°C of temperature; 30-60 bar of pressure; 1.0-3.0 cm3/cm3h of liquid hourly space velocity (LHSV) and 200-600 Nm3/m3 hydrogen/hydrocarbon ratio. According to the results it was concluded that 60-78% of the normal paraffin content of the feedstock having a CFPP value of +7°C was converted to iso-paraffins at the favorable process parameters (T=350-360°C; P=40-50 bar; liquid hourly space velocity= 1.0-1.3 h-1; H2/hydrocarbon ratio: 250 Nm3/m3). Accordingly the CFPP value of the products was between -4°C and -14°C. These products are excellent blending components of Diesel fuels. Furthermore in the temperate zone they can satisfy all of the specification of the winter grade Diesel fuel standard as pure fuels with some additives, (some components 140 mg/kg and 40 mg/kg of flow improver and paraffin dispersant respectively) as well.
