A SHC apparatus and process comprise a catalyst precursor reactor for providing a catalyst precursor stream in downstream communication with a source of molybdenum, a SHC feed line for providing a heavy hydrocarbon feed stream in downstream communication with a heater, and a SHC reactor in downstream communication with the SHC feed line and with the catalyst precursor reactor. A process for SHC, the process comprising preparing a catalyst precursor stream comprising molybdenum in a catalyst precursor reactor, mixing the catalyst precursor stream with a heavy hydrocarbon stream to provide a catalyst precursor concentrate stream, heating a hydrocracking hydrocarbon feed stream in a heater to provide a heated hydrocracking feed stream, mixing the catalyst precursor concentrate stream with the heated hydrocarbon stream to provide a SHC feed stream, and reacting the SHC feed stream in a SHC reactor.
