Abstract

In this paper, we prepared Dipentene Hydrogenation Catalyst by impregnating, with activated alumina as catalyst carrier and nickel nitrate solution as soaking liquid. The objective of this study was to investigate the influences of the amount of nickel loading, calcination temperature and hydrogen reduction temperature on catalyst activity. The results show that the optimum parameters are: 21% of nickel loading, the calcination temperature of 550-650 °C, the hydrogen reduction temperature of 325-350 °C. The purity of p-menthane prepared under the conditions was more than 97 %, reaching special class standards.
