Abstract

Long term experiments were carried out on Pt/sulfated-zirconia catalyst at 160°-200°C, 20 bar total pressure, 1:1 H2/hydrocarbon molar ratio, and 1/hr-4/hr liquid hourly space velocity in large scale laboratory catalytic reactor with different benzene and cycloparaffin containing fractions. Isomerization of these fractions and the effect of process parameters on composition, yield, and octane numbers of liquid products were studied. When the reaction temperature increased, these reactions became faster and the rate and selectivity of hydrocracking and ring opening reactions also increased. Ring opening reactions resulted in higher concentration of hexane isomers. However, decreasing the conversion rate of cycloparaffins led to decreased octane number. When the rate of the isomerization reaction, e.g., residence time, increased, the individual cyclo-, iso-, and normal C6 paraffins concentrations became comparable with each other. This is an abstract of a paper presented at the CHISA 2012 - 20th International Congress of Chemical and Process Engineering and PRES 2012 - 15th Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction (Prague, Czech Republic 8/25-29/2012).
