Abstract:
1. A process for cracking a hydrocarbon-containing feedstock, comprising: providing a hydrocarbon-containing feedstock to a mixing zone, where the hydrocarbon-containing feedstock is selected to contain at least 20 wt. % hydrocarbons having a boiling point of greater than 538° C. as determined in accordance with ASTM Method D5307 providing at least one metal-containing catalyst to the mixing zone, wherein any metal-containing catalyst provided to the mixing zone has an acidity as measured by ammonia chemisorption of at most 200 μmol ammonia per gram of catalyst; providing hydrogen to the mixing zone and mixing the hydrogen, the hydrocarbon-containing feedstock, and the catalyst(s) in the mixing zone at a temperature of from 375° C. to 500° C. and at a total pressure of from 6.9 MPa to 27.5 MPa to produce: continuously or intermittently separating at least a portion of the vapor from the mixing zone while retaining at least a portion of the hydrocarbon-depleted feed residuum and at least a portion of the catalyst(s) in the mixing zone, wherein the vapor separated from the mixing zone comprises at most 5 wt. % solids and liquids at the temperature at which the vapor is separated from the mixing zone; and apart from the mixing zone, condensing a liquid hydrocarbon-containing product that contains at least 90% of the atomic carbon initially contained in the hydrocarbon-containing feedstock and that contains less than 5 wt. % hydrocarbons having a boiling point of at least 538° C. as determined in accordance with ASTM Method D5307 from at least a portion of the vapor separated from the mixing zone.
