Several types of activated carbon and various methods for the pretreatment of the support were used for impregnating the palladium. Depending on the method of pretreating the activated carbon with base and/or acid, the catalyst activity showed the following trend; 0.5 M NaOH and 0.5 M HCl>0.5 M HCl>0.5 M HNO3>0.5 M HF>non-pretreated carbon. The granular-type catalyst exhibited the highest conversion and selectivity to HFC-152a.
