    摘要: A catalyst, e.g., a cracking catalyst, and a part of the regeneration fumes are drawn off from the dense catalytic bed of a second regenerator (9) and are introduced by force of gravity into an external exchanger (21) at a junction point beneath the level of the dense bed of the second regenerator. The heat exchange takes place in the bottom part of the exchanger below the junction point. Between the bottom end of the exchanger and the region above the junction point a dense bed zone is formed at a level which is substantially at the height of the dense bed in the regenerator and a discharge zone (27), of suitable size, for the regeneration gases and fluidization gas. The gases and fumes from the exchanger are removed in the diluted fluidized phase from the second regenerator through a conduit (28), while the catalyst is recycled in to the bed of the first regenerator through a conduit (34).

    摘要: A process and apparatus for the heat regulation of fluidized or fluid catalyst beds are described, the apparatus having a fluid bed heat exchanger. According to the invention, a pulverulent solid is made to flow essentially from the base of an enclosure (1) into a heat exchanger (6) having an internal separating partition (22) which defines two elongated, adjacent compartments (23, 24) communicating at their lower part. In the compartment in which the pulverulent solid flows downwards, the fluidization speed or rate is between 0.1 cm to 2 m/s, whereas in the compartment wherein the pulverulent solid rises again into the heat exchanger (6), the fluidization speed is between 0.1 and 6 m/s. The invention can be used for refining reaction (e.g., catalytic reforming), for the regeneration of a fluidized bed catalytic cracking catalyst of a petroleum or oil charge, or for the combustion of coal.

    摘要: A gas siphon type reactor (10) is used to carry out a three phase chemical reaction under pressure, such as the reduction of uranyl nitrate to uranous nitrate by hydrogen, in the presence of a catalyst made up of platinum on a silica carrier. The control of the pressure in the reactor (10) is provided by regulating the liquid and gas flow rates from a high pressure separator (52), into which the liquid and the gas leaving the reactor (10) are routed. The liquid in the reactor (10) is tapped from a lateral branch pipe (32) fitted with a filter (36) and emerging in the upper area (30), behind a profiled wall (34).

    摘要: A process is described for catalytic cracking of a petroleum feed in which a catalyst from a regeneration zone 4 is caused to flow in a dense fluidized bed conditioning zone 2 upstream of an injection zone 10, the fluidization rate being 0.1 to 30 cm/s. The throughput of catalyst into injection zone 10 is regulated by a constriction means 11. The hydrocarbon feed 12 is injected below the constriction means and flows counter-current to the direction of flow of the shaped catalyst flow. The hydrocarbon feed 12 is injected at a set injection angle depending on the movement of the feed and the catalyst.
