Systems and methods are provided for slurry hydroconversion of a heavy oil feedstock, such as an atmospheric or vacuum resid, in the presence of an enhanced or promoted slurry hydroconversion catalyst system. The slurry hydroconversion catalyst system can be formed from a) a Group VIII non-noble metal catalyst precursor/concentrate (such as an iron-based catalyst precursor/concentrate) and b) a Group VI metal catalyst precursor/concentrate (such as a molybdenum-based catalyst precursor/concentrate) and/or a Group VI metal sulfided catalyst.
1. A method for forming a slurry catalyst, comprising: dispersing a first catalyst precursor comprising iron and a second catalyst precursor comprising molybdenum in a hydrocarbonaceous material comprising a heavy oil fraction, an amount of molybdenum in the second catalyst precursor in the hydrocarbonaceous material being about 250 wppm or less, based on inclusion of the catalyst/system into a heavy oil feedstock to be hydroconverted, a weight ratio of the iron in the first catalyst precursor to the molybdenum in the second catalyst precursor in the hyd...
