    摘要: A hydroprocessing process includes a cocurrent flow liquid reaction stage, a countercurrent flow liquid reaction stage and a vapor reaction stage in which feed components are catalytically hydroprocessed by reacting with hydrogen. Both liquid stages both produce a liquid and a vapor effluent, with the cocurrent stage liquid effluent the feed for the countercurrent stage and the countercurrent stage liquid effluent the hydroprocessed product liquid. Both liquid stage vapor effluents are combined and catalytically reacted with hydrogen in a vapor reaction stage, to form a hydroprocessed vapor. This vapor is cooled to condense and recover a portion of the hydroprocessed hydrocarbonaceous vapor components as additional product liquid. The uncondensed vapor is rich in hydrogen and is cleaned up if necessary, to remove contaminants, and then recycled back into the cocurrent stage as hydrogen-containing treat gas. Fresh hydrogen is introduced into the countercurrent stage and the countercurrent stage effluent contains sufficient, and preferably all of the hydrogen for the vapor stage reaction.

    摘要: A reactor is provided for reacting a liquid with a treat gas in the presence of a catalyst, the reactor comprising a continuous wall enclosing a first reaction zone, wherein the first reaction zone includes a catalyst for causing a desired reaction between the liquid and the treat gas; a liquid inlet above the first reaction zone for allowing an unreacted portion of the liquid to enter the reactor; a gas inlet below the first reaction zone for allowing an unreacted portion of the treat gas to enter the reactor; a liquid outlet below the first reaction zone for allowing a reacted portion of the liquid to exit the reactor; a gas outlet above the first reaction zone for allowing a reacted portion of the treat gas to exit the reactor; and a liquid bypass device in the first reaction zone for allowing a portion of the liquid to bypass a portion of the first reaction zone, the liquid bypass device including a liquid bypass regulating device for regulating the amount of liquid which bypasses the first reaction zone. In a preferred embodiment, a plurality of reaction zones are present, and a liquid distribution tray is disposed above each reaction zone. Preferably, the liquid bypass device creates a hydrostatic seal with the liquid accumulating in the distribution tray so that the timing and extent of liquid bypass is self-regulating based on predefined flooding conditions.

    摘要: A hydroprocessing process includes two cocurrent flow liquid reaction stages and one vapor stage, in which feed components are catalytically hydroprocessed by reacting with hydrogen. The liquid stages both produce a liquid and a hydrogen-rich vapor effluent, with most of the hydroprocessing accomplished in the first stage. The first stage vapor is also hydroprocessed. The hydroprocessed vapor and second stage vapor are cooled to condense and recover additional product liquid and produce an uncondensed hydrogen-rich vapor. After cleanup to remove contaminants, the hydrogen-rich vapor is recycled back into the first stage as treat gas. Fresh hydrogen is introduced into the second stage. This is useful for hydrotreating heteroatom-containing hydrocarbons.

    摘要: A process for producing distillate boiling range streams that are low in both sulfur and aromatics. A distillate feedstock is treated in a first hydrodesulfurization stage in the presence of a hydrogen-containing treat gas and a hydrodesulfurization catalyst, thereby resulting in partial desufurization of the stream. The partially desulfurized distillate stream is then treated in a second hydrodesulfurization stage, also in the presence of a hydrogen-containing treat gas and a hydrodesulfurization catalyst. The hydrogen-containing treat gas is cascaded from the next downstream reaction stage, which is an aromatics hydrogenation stage.
