Abstract
In a method of hydroprocessing, hydrogen gas for the hydroprocessing reaction is combined with a liquid feed composition comprising a feedstock to be treated and a diluent to form a feed stream, at least a portion of the hydrogen gas being dissolved in the liquid feed composition of the feed stream, with non-dissolved hydrogen gas being present in the feed stream in an amount of from 1 to 70 SCF/bbl of the liquid feed composition. The feed stream is contacted with a hydroprocessing catalyst, within a reactor while maintaining a liquid mass flux within the reactor of at least 5000 lb/hr·ft2 to form a hydroprocessed product.
Claims20
A method of hydroprocessing comprising:
- combining hydrogen gas for the hydroprocessing reaction with a liquid feed composition comprising a feedstock to be treated and a diluent to form a feed stream, at least a portion of the hydrogen gas being dissolved in the liquid feed composition of the feed stream, with non-dissolved hydrogen gas being present in the feed stream in an amount of from 1 SCF to 70 SCF per bbl of the liquid feed composition;
- and
- contacting the feed stream with a hydroprocessing catalyst within a reactor while maintaining a liquid mass flux within the reactor of at least 5000 lb/hr·ft2 to form a hydroprocessed product.
A method of hydroprocessing comprising:
- combining hydrogen gas for the hydroprocessing reaction with a liquid feed composition comprising a feedstock to be treated and a diluent to form a feed stream, at least a portion of the hydrogen gas being dissolved in the liquid feed composition of the feed stream, with non-dissolved hydrogen gas being present in the feed stream in an amount of from 1 SCF to 50 SCF per bbl of the liquid feed composition;
- and
- contacting the feed stream with a hydroprocessing catalyst contained in at least two catalyst beds contained within a reactor while maintaining a liquid mass flux within the reactor of from 10,000 lb/hr·ft2 to 100,000 lb/hr·ft2 to form a hydroprocessed product.
The method of claim 19, wherein:
- the separated gas is removed from the reactor at a rate so that the volume of gas within the reactor is maintained in a near stagnant condition.
