HYDROCONVERSION MULTI-METALLIC CATALYST AND METHOD FOR MAKING THEREOF
摘要
A method for preparing a bulk multi-metallic suitable for hydrotreating heavy oil feeds is provided. In one embodiment of the process of preparing the catalyst precursor which is subsequently sulfided to form the bulk catalyst, a catalyst precursor filter cake is treated with at least a chelating agent, resulting in a catalyst precursor with optimum porosity. In another embodiment, non-agglomerative drying is employed to keep the catalyst precursor from aggregating / clumping. The catalyst precursor obtained herein has an optimum porosity with at least 90% of the pores being macropores and a total pore volume of at least 0.08 g/cc.
