活性炭负载的铑和钌催化剂在低温（323 K）和超临界二氧化碳条件下对联苯加氢合成双环己基具有较高的活性和选择性。联苯加氢转化率随二氧化碳分压和氢气分压的增加而增加。在两种催化剂上，从反应开始就生成环己基苯和双环己基苯，最终双环己基苯的产率>95%。
Charcoal-supported rhodium and ruthenium catalysts were active and selective for the hydrogenation of biphenyl to bicyclohexyl at low temperature (323 K) under supercritical carbon dioxide. The conversion of biphenyl hydrogenation increased with increase in carbon dioxide pressure and hydrogen pressure. From the beginning of reaction, cyclohexylbenzene and bicyclohexyl were formed and finally >95% yield of bicyclohexyl was obtained over the both catalysts.
