Abstract
A process using a dealkylated aromatic liquid improves a heavy hydrocarbon liquid used for supporting molybdenum carbonized catalyst. Dealkylated aromatic liquid can be derived from heavy hydrocarbon materials that have been subjected to cracking, such as fluid catalytic cracking or slurry hydrocracking. The heavy hydrocarbon liquid can comprise a portion of resid SHC feed and a portion of a gas oil stream from SHC effluent.
Claims20
A process of slurry hydrocracking comprising:
- mixing a molybdenum catalyst precursor, a dealkylated aromatic liquid comprising no more than about 11.0 wt % hydrogen and an asphaltenic liquid comprising at least 5 wt % microcarbon residue to provide a catalyst precursor concentrate;
- heating the catalyst precursor concentrate to an elevated temperature to form a slurry catalyst;
- and
- charging said catalyst precursor concentrate and a resid feed stream to a slurry hydrocracking reactor.
A method of making a catalyst concentrate comprising:
- mixing a molybdenum catalyst precursor, a dealkylated aromatic liquid comprising no more than about 11.0 wt % hydrogen and an asphaltenic liquid comprising at least 5 wt % microcarbon residue to provide a catalyst precursor mixture;
- and
- heating the catalyst precursor mixture to an elevated temperature to form a catalyst concentrate, wherein the dealkylated aromatic liquid comprises about 10 to about 70 wt % of the catalyst concentrate.
A method of making a slurry catalyst comprising:
- mixing a molybdenum catalyst precursor, a dealkylated aromatic liquid comprising no more than about 11.0 wt % hydrogen, an asphaltenic liquid comprising at least 5 wt % microcarbon residue and sulfur to provide a catalyst precursor mixture;
- heating said catalyst precursor mixture to dehydrate said catalyst precursor mixture and provide a catalyst precursor concentrate;
- heating the catalyst precursor concentrate to an elevated temperature to form a catalyst concentrate;
- and
- adding said catalyst concentrate to a feed resid stream to provide a catalyst concentrated resid stream.
