    Abstract: A reactor for catalytically dewaxing a waxy distillate consisting of a lubricating oil or liquid petroleum feedstocks utilizing a shape-selective crystalline aluminosilicate zeolite catalyst in order to obtain a lubricating oil having a low pour point and a high viscosity index, particularly, a plate-type hydroprocessing trickle reactor construction for catalytically dewaxing liquid petroleum feedstocks. The reactor is essentially constituted of an inclined plate trickle bed reactor wherein a tray of generally permeable construction supports a bed of catalyst material, such as crystalline zeolite, and in which the liquid petroleum feedstock trickles downwardly through the catalyst material from the upper end of the reactor towards the lower end of the reactor, while hydrogen is concurrently injected into the space below the permeable tray at the upper end of the reactor in the direction towards the lower end of the reactor. The hydrogen, under a slight superpressure passes through the permeable plate and percolates through the catalyst bed to thereby contact and efficiently strip the downwardly trickling stream of liquid petroleum feestock of low boiling conversion products or waxy components, such as naphtha. The generated gases resulting from the reaction, such as hydrogen, naphtha and LPG are collected in a head space provided above the catalyst bed on the permeable plate, and are scavenged at one end of the reactor through entrainment in an inert carrier gas introduced into the reactor at the opposite end thereof and which flows through the head space above the catalyst.

    Abstract: An improved version of an osmotically driven mini-osmotic pump that is used to administer drug solutions. The basic components of the improved pump are: an inner flexible bag that holds the drug solution; a plug having a recessed inner end that seals the bag opening; a solution filling/discharge port through the plug; a cup-shaped, thermo-formed sleeve that fits partly about the bag and is made from a dispersion of an osmotically effective solute in a water soluble, theroplastic polymer vehicle; a shape-retaining, semipermeable membrane that encapulates the bag-sleeve subassembly; and a flow moderator that is received through the filling/discharge port in the plug.

    Abstract: An osmotic system is disclosed for dispensing a beneficial agent. The system comprises (1) a first wall of a semipermeable material that surrounds a compartment containing a drug formulation, and has a passageway through the wall for releasing agent from the compartment, (2) a second wall positioned distant from the first wall, said second wall a microporous or hydrogel material that extends around the first wall, and (3) a distribution zone interposed between the first and second wall and initially housing a compound soluble in an external fluid that enters the system.In operation, agent is dispensed from the system by fluid passing through the second wall into the zone from which fluid is further being imbibed through the first wall into the compartment forming a solution that is released through the passageway into the zone, and then through the second wall to the exterior of the system.

    Abstract: The present disclosure discloses a device and a method for continuously producing catalysts based on low-temperature coprecipitation. The device mainly includes: a metal salt preparation kettle, a primary reaction kettle, a secondary reaction kettle, a precipitant preparation kettle, a circulating refrigeration system, an automatic control system, a non-aqueous solvent storage tank and a water storage tank. Independent preparation kettles are provided for rapid dissolution of the raw materials, and can be used to prepare the raw materials for the next batch during the reactions that are carried out in the primary and secondary reaction kettles; the circulating refrigeration system refrigerates the primary and secondary reaction kettles, and thus during the reaction, the low-temperature precipitant makes it possible to offset the precipitation reaction heat and the heat caused by the stirring in the primary reaction kettle, and improve the refrigeration efficiency of the primary reaction kettle.
