Based on the reaction mechanism of resid hydrodemetallization,a new catalyst carrier was designed and prepared.As compared with the similar type of catalyst carrier,the said new carrier featured a higher pore volume,a larger pore diameter and a weaker surface acidity,which could im- prove the diffusion performance and stable reaction performance of the catalyst.The active metal components were loaded on the said carrier by a new technique for better metal dispersion,thus the impurity removal rate of the new catalyst,RDM-3,was improved significantly.The commercial test of the RDM-3 catalyst showed that the process of catalyst preparation was stable,the catalyst perfor- mance was slightly better than the catalyst prepared in the lab,therefore,the catalyst could be manu- factured in commercial scale.
