실험 절차
A 5/8"×18" stainless steel pipe downflow trickle bed reactor was charged with 25 ml Pyrex glass beads followed by 15 ml (10.9 g.) of the above catalyst and topped by additional Pyrex glass beads to give a total charged volume of about 25 ml. The system was pressure checked, heated to 150° C., and pressured to 500 psig with hydrogen for 15 minutes. During a reaction period of four hours, benzene was pumped into the stainless steel tube reactor at a rate of 300 ml/hr (LHSV=20) at a hydrogen pressure of 500 psig and a temperature of 215° C. The reactor effluent was collected in a receiver which was changed at approximately one hour intervals, and the composition of each sample was determined by gas chromatographic analysis. The gas chromatographic analyses of samples taken during the last four hours of a run were averaged and the results showed a 1.4% conversion based on benzene, with a selectivity of 62% to cyclohexylbenzene and 19% to cyclohexane. The ratio of cyclohexylbenzene/cyclohexane (CHB/CH) was 3.3.
