    Abstract: PROBLEM TO BE SOLVED: To provide an integrated process to produce a larger amount of olefins in cracked products and to maximize the quality and octane value of distillate by integrating a hydrotreatment process into a catalytic cracking process. SOLUTION: The product from a catalytic cracking apparatus 12 is sent to a separation (step) container 17 and separated into a light end fraction having a boiling point of below 600 deg.F and a naphtha. The bottom fraction containing a middle distillate and a gas oil is transferred via a line 18 into which a hydrogen-containing gas stream is injected at a desired rate and sent to a hydrotreatment reactor 19. After the hydrotreatment, excess hydrogen is recovered, and the product is transferred to a separator 20. The hydrotreated gas-oil-containing bottom fraction obtained by separating the naphtha, the light end and the middle distillate is partially purged and fed again to the reactor 12 via a line 21. The hydrogenation reaction is desirably carried out at 600-850 deg.F under a pressure of 500-2,000psig and at an hourly space velocity of 0.3-2v/v/hr.

    Abstract: PROBLEM TO BE SOLVED: To increase the flow rate of a liquid passing through a reaction bed of a reactor for reacting a liquid flow of petroleum or of a chemical with a treating gas contg. hydrogen in the presence of a catalyst in a countercurrent reaction zone by installing a means for causing at least a part of the treating gas to bypass the reaction zone. SOLUTION: The reactor includes a catalyst bed 4 for causing the reaction between a liquid flow and a treating gas, a nonreaction zone installed in contact with the upstream side of the reaction zone, and a gas-liquid contact zone installed in the nonreaction zone and equipped with an open-structured contact means made of a solid substance. In this reactor, a liquid-introducing means 6 for introducing the unreacted portion of a liquid flow into the reactor is installed at the upper part of the nonreaction zone; a means 8 for leading the unreacted portion of the treating gas to the reactor 1 is installed at the lower part of the reaction zone; a liq. discharge means 10 for discharging the reacted portion of the liquid flow is installed at the lower part of the reaction zone; a means 12 for discharging the reacted portion of the treating gas is installed at the upper part of the nonreaction zone of the reaction zone; and a means 14 for causing the treating gas to bypass the reaction zone is installed along the reaction zone.

    Abstract: PROBLEM TO BE SOLVED: To provide an integrated process to produce a larger amount of olefins in cracked products and to maximize the quality and octane value of distillate by integrating a hydrotreatment process into a catalytic cracking process. SOLUTION: The product from a catalytic cracking apparatus 12 is sent to a separation (step) container 17 and separated into a fraction containing a relatively light gasoline and a vapor and having a boiling point of below 300 deg.F. The bottom fraction containing a middle distillate and a gas oil is sent to a hydrotreatment apparatus 19 via a line 18. This apparatus contains a hydrotreatment catalyst and may be of the type of fixed or moving bed. After the hydrotreatment, excess hydrogen is recovered, and the product is transferred to a separator 20. The naphtha fraction and the middle distillate are recovered via lines 26 and 28, respectively. The hydrotreated gas-oil-containing bottom fraction are fed again into the apparatus 12 via lines 22 and 23. The hydrotreated light end fraction is recovered via a line 27.

    Abstract: A hydroprocessing process is disclosed which includes two hydroprocessing reaction stages represented by vessels (12) and (14), both of which produce a liquid and vapor effluent represented by lines (42) and (54), and a liquid vapor contacting stage. The first vapor effluent contains impurities, such as heteroatom compounds, which are removed from the vapor by contact with processed liquid effluent derived from one or both reaction stages in contact vessel (20) and optionally also liquid recovered from processed vapor. The first and contact stage liquid effluents are passed into the second stage vessel (14) to finish the hydroprocessing. The contact and second stage vapor effluents are cooled to recover additional hydroprocessed product liquid in lines (58) and (64).

    Abstract: A process for hydroprocessing middle distillate petroleum streams in two temperature stages is disclosed. The feedstream (11) is hydroprocessed in two or more first temperature stages operated at a temperature from about 360 to about 450 degrees celsius. The reaction product (13) of the first temperature stage(s) is quenched to a temperature from about 260 to about 350 degrees celsius, stripped of hydrogen sulfide, ammonia and other dissolved gases to form a reaction product (17) which is sent to a second temperature stage which is operated at said quenched temperature range. The product from the second temperature stage is also stripped of dissolved gases in a stripping zone (16b). Color bodies produced in the higher temperature first stage are hydrogenated in the last stage.

    Abstract: A process for hydroprocessing liquid petroleum and chemical streams in a single reaction vessel (100) containing two or more hydroprocessing reaction stages (110a, 110b, 110c). The liquid product from the first stage (110a) is stripped of H2S, NH3 and other gases, then sent to the next downstream reaction zone (110b). The product from the downstream reaction zone (110b) is also stripped of dissolved gases and sent to the next downstream reaction stage (110c) until the last reaction stage (110c), the liquid product of which is stripped of dissolved gases and collected or passed on for further processing. The flow of treat gas is in a direction opposite the direction in which the reaction stages (110a, 110b, 110c) are staged for the flow of liquid.
