    Abstract: PURPOSE: To enhance reaction productivity by consisting of a heteropolyacid catalyst and polysulfone membrane to be excellent in separation characteristicity of material compared with a traditional reactor vessel using an inorg. membrane as a separating membrane and simultaneously proceeding a reaction process and a separation process. CONSTITUTION: This reactor provides a disklike first body 2 equipping with a raw material-injecting opening 3 at a center part, a catalyst support 5 equipping with a hole 6 of a truncated cone form for introducing the flow of the material at the center part and holding a teheropolyacid layer 4 in the hole 6, a disklike second body 7 equipping with a buffer region 8 for staying the reactant transported from the hole 6 at the center part and an outlet 9 of eliminated substances at side walls, a porous support 11 equipping with a polysulfone membrane 10 for penetrating the objective reactant in the buffer region 8 at upper side and a disklike third body 14 equipping with a discharging opening 15 at a center part for discharging the objective reactant penetrated the polysulfone membrane 10 these parts are overlapped according to the above order. Gaps of these parts are connected with O-rings 16 to make airtight. As the result, the reaction process and the separation step are proceeded at the same time and the reaction productivity is enhanced.

    Abstract: PURPOSE:To obtain an energy-saving type chemical reactor easily supplying fine chemical reaction gas bubbles to a chemical reaction solution by providing a chemical reaction solution transfer pipe such as a porous pipe in a chemical reaction gaseous atmosphere in an exposed state. CONSTITUTION:The exhaust gas discharged from a steam power plant is introduced into an absorbing tower 20 to be brought into contact with a lime slurry. Whereupon, sulfur dioxide in the exhaust gas is reacted with lime to become calcium sulfite which is, in turn, oxidized in an oxidizing device 21 to be converted to stable gypsum. At this time, the flowing liquid containing calcium sulfite is guided to an absorbing solution storage tank 11 from the absorbing tower 20 and supplied to a suction type chemical reaction gas feeder 30 through a chemical reaction solution transfer pipe 4 to be oxidized. The suction type chemical reaction gas feeder 30 is constituted of a ceramic porous pipe 1 and a chemical reaction gas transfer pipe 2 made of an acrylic resin and the contact area of the gas bubbles from the pores of the porous pipe 1 with the reaction solution is large and the taking-in rate of the feeder 30 is enhanced.

    Abstract: PURPOSE:To obtain polymer particles of a uniform particle diameter stably without using any suspension protecting agent which requires waste water treatment by polymerizing a polymerizable liquid by a specified system by injecting it from an orifice into an aqueous dispersion of a water-insoluble inorganic substance suspending agent under application of vibrational agitation while controlling the amount of adsorption. CONSTITUTION:An aqueous dispersion containing a suspending agent based on a water-insoluble inorganic substance (desirably calcium phosphate) is fed to a column provided with an orifice 3 having at least one hole through a feed line 5, and a polymerizable liquid having a specific gravity smaller than that of the dispersion is injected through the hole of the orifice 3 under application of a vibration with a vibrator 9. This mixture is fed through a pipe 8 to the first reactor 14 and recirculated to the bottom of the reactor 14, heat exchanger 19 to the top of the reactor, and partially polymerized while controlling the amount of the suspending agent adhering to the surface of a droplet of the polymerizable liquid, and the solution is sent to the second reactor 24 to stop the polymerization.
