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 the process of preparing the catalyst precursor which is subsequently sulfided to form the bulk catalyst, non-agglomerative drying is employed to keep the catalyst precursor from aggregating/clumping, resulting in a catalyst precursor with optimum porosity with at least 90% of the pores being macropores, and having a total pore volume of at least 0.08 g/cc. |
