Sažetak
Isomerization of n-hexane is process that produces high octane value isomers, which are environmentally friendly components used for blending of motor fuels. Pt/SO4 2- /ZrO2 represents the latest generation of isomerization catalysts, whose activity depends on feed structure and process parameters. Increased demand for petroleum products in last few years has resulted in processing of lower quality feeds, which contain compounds that negatively affect the kinetics and thermodynamics of the process. In this work we studied the effect of benzene on the isomerization process of n-hexane. Solutions of benzene in n-hexane were used as feedstocks, with benzene contents of 1, 2, 3 and 4 %. The temperature range in which the experiments were conducted was 130-170 °C. Additional process parameters which were varied in order to test process efficiency were hydrogen to hydrocarbon ratio and liquid hourly space velocity (LHSV). The results indicate a decrease in conversion of n- hexane with increasing concentration of benzene in the feed, especially at lower temperatures and higher values of space velocity and the hydrogen to hydrocarbon molar ratio.
