Abstract
In one exemplary embodiment, a system for reacting a first feed can include a petroleum fraction having at least about 90%, by volume, with a boiling point of at least about 300° C. The system can include a bubble column reactor. The bubble column reactor, in turn, can include a first inlet for the first feed and a second inlet for a second feed including a gas rich in hydrogen. In addition, the petroleum fraction may be in counter-current flow with respect to the gas rich in hydrogen inside the bubble column reactor.
Claims16
A process for reacting a first feed comprising a petroleum fraction stream having at least about 90%, by volume, with a boiling point of at least about 300° C., comprising receiving in a bubble column reactor the first feed including the petroleum fraction combined with one or more catalyst particles and passing counter-currently the petroleum fraction entraining the one or more catalyst particles with respect to a gas rich in a hydrogen gas in the bubble column reactor, wherein the first feed including the petroleum fraction entraining the one or more catalyst particles is received in the bubble column reactor proximate to a top of the bubble column reactor;
- controlling a liquid level in the bubble column reactor to allow the petroleum fraction to disengage from the hydrogen gas in a gap above an inlet for the first feed in the bubble column reactor.
A process for reacting a first feed comprising a petroleum fraction stream having at least about 90%, by volume, with a boiling point of at least about 300° C., comprising receiving a catalyst stream proximate to a top of a first bubble column reactor and passing counter-currently the petroleum fraction entraining the catalyst stream with respect to a gas rich in a hydrogen gas in the first bubble column reactor;
- controlling a liquid level in the first bubble column reactor to allow the petroleum fraction to disengage from the hydrogen gas in a gap above an inlet for the first feed in the first bubble column reactor;
- said first bubble column reactor producing a base product comprising at least a partially converted petroleum fraction suspending catalyst particles and receiving said base product in a second bubble column reactor and operating said second bubble column reactor at about 5 to about 50° C. higher than said first bubble column reactor.
