1. A method of mixing a catalyst precursor into a heavy oil feedstock, comprising:
providing a catalyst precursor having a decomposition temperature;
providing a high boiling hydrocarbon diluent comprised of one or more high boiling hydrocarbons having a nominal boiling point of at least 524° C. and optionally one or more medium boiling hydrocarbons having a nominal boiling point in a range of about 200° C. to 524° C., the high boiling hydrocarbon diluent initially having a temperature above the decomposition temperature of the catalyst precursor;
cooling the high boiling hydrocarbon diluent to a temperature below the decomposition temperature of the catalyst precursor, wherein cooling is performed by at least one of passing the high boiling hydrocarbon diluent through one or more coolers or heat exchangers or mixing the one or more high boiling hydrocarbons with one or more initially cooler medium boiling hydrocarbons;
mixing the catalyst precursor with the high boiling hydrocarbon diluent to form a diluted precursor mixture; and
mixing the diluted precursor mixture with the heavy oil feedstock to form a conditioned feedstock.
