초록
상온 이온성액체 중 하나인 1-hexyl-3-methylimidazolium tetrafluoroborate을 이용하여 팔라듐이 담지된 탄소입자를 제조하였다. 제조된 입자는 hexafluoropropylene (HFP) 수소화 반응용 촉매로 사용되었다. 또한 최적의 수소화 반응공정을 개발하기 위하여 다양한 반응조건에서 반응을 수행하였다. 팔라듐의 함량의 경우 3 wt% 이상을 유지하고 이온성액체와 팔라듐전구체의 몰비가 1 : 1로 합성된 촉매가 우수한 수소화 반응성을 보였다. 반응조건의 경우 수소와 HFP의 유량비가 1.25 이상이고 GHSVHFP는 50000 mL/g-h 이하일 때 전환율 100%를 달성하였다.
Palladium on carbon powder was prepared using 1-hexyl-3-methylimidazolium tetrafluoroborate, one of room temperature ionic liquids. The synthesized particles were tested as a hexafluoropropylene hydrogenation catalyst. Moreover, the hydrogenation was performed under various reaction conditions to develop an optimum reaction process. The catalyst prepared by more than 3 wt% of palladium and the unity mole ratio of ionic liquid to palladium precursor showed higher catalytic activity. For reaction onditions, the complete hexafluoropropylene (HFP) conversion was achieved at these conditions; the volume flow ratio of hydrogen to HFP was higher than 1.25 and GHSVHFP was lower than 50000 mL/g-h.
