    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： The distribution of fluid flowing through a packed bed reactor is determined by placing a plurality of fiber optic sensors at desired locations within the packed bed reactor. A light analyzable tracer component is injected into the fluid flowing through the reactor. Light is supplied to each of the sensors causing any tracer component in the vicinity of the sensor to emit electromagnetic radiation. The emitted electromagnetic radiation is detected at each fiber optic sensor, thereby permitting the amount of tracer in the vicinity of each sensor to be determined, and consequently providing a measure of the distribution of fluid flowing through the reactor.
