    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 distillate fuel feed is hydrotreated to remove heteroatoms and then separated into light and heavy hydrotreated fractions, with the heavy fraction catalytically dewaxed to improve low temperature properties. The hydrotreating and dewaxing are conducted in separate stages, which may be in the same reactor vessel. Fresh hydrogen may be passed into the dewaxing stage, with the dewaxing stage gaseous effluent then passed into the hydrotreating stage to provide hydrogen for the hydrotreating. Existing hydrotreating reaction vessels and facilities may be retrofitted to add one or more dewaxing stages.

    摘要： Disclosed is a catalytic cracking process which includes more than one catalytic cracking reaction step. The process integrates a hydroprocessing step between the catalytic cracking reaction steps in order to maximize olefins production, distillate quality and octane level of the overall cracked product. Preferably, the hydroprocessing step is included between the reaction stages, and a portion of the hydroprocessed products, i.e., a naphtha and mid distillate fraction, is combined with cracked product for further separation and hydroprocessing. It is also preferred that the first catalytic cracking reaction step be a short contact time reaction step.

    摘要： A three stage hydroprocessing process includes two liquid and one vapor reaction stages, both of which produce an effluent comprising liquid and vapor. Both vapor effluents comprise vaporized hydrocarbonaceous material. Fresh hydrogen is used for the hydroprocessing in both liquid stages. The second stage liquid effluent comprises the product liquid. The first stage liquid effluent is the feed for the second stage. The first stage vapor effluent is hydroprocessed in the vapor stage and then cooled to condense and recover at least a portion of the processed vapor as additional product liquid.
