摘要： The invention relates to a process for drying a catalyst carrier or drying a catalyst comprising a carrier on which a metal is supported, wherein the carrier or catalyst is contacted with a drying agent which comprises an organic carbonate. Further, the invention relates to a process for preparing a catalyst which comprises a carrier on which a metal is supported, said process comprising drying the carrier by contacting the carrier with a drying agent which comprises an organic carbonate resulting in a dried carrier; and impregnating the dried carrier with a solution wherein a compound containing the metal is dissolved in a solvent which is an organic carbonate or an alcohol. Still further, the invention relates to a process for preparing an aromatic carbonate, such as a diaryl carbonate, using the catalyst thus prepared or dried; and to a process for making a polycarbonate from the diaryl carbonate thus prepared.
