Abstract: Ethylene oxide is produced by the partial oxidation of ethylene by gaseous oxygen in the presence of a silver-containing catalyst and from 0.001 to 2 parts per million by volume, based upon the gaseous feed mixture, of a halogen, hydrohalide, ammonium halide or halogenated hydrocarbon.  The reaction is preferably carried out at temperatures in the range 150-400 DEG  C.  In the example, a gaseous mixture containing ethylene, oxygen and inert gases is passed through an elongated vertical reactor containing a silver-containing catalyst and about one part per million of feed of ethylene dichloride to give ethylene oxide.  The catalyst is prepared by mixing a solution of silver nitrate with sodium hydroxide solution, adding barium or calcium lactate, coating spheres of mullite with the resulting slurry and then heating them.ALSO:A silver-containing catalyst for use in the oxidation of ethylene to ethylene oxide is prepared by mixing an aqueous solution of silver nitrate with a slight excess of caustic soda solution, filtering off the precipitated silver oxide formed and adding to it an aqueous solution of barium or calcium lactate; spheres of mullite are added to the resulting mixture which is then evaporated until the spheres are coated with the slurry; the spheres are then roasted.

A device for loading bulk materials, e. g. rock, into a high pressure water pipe-line comprises a pair of lock chambers 3, 4, which are alternatley charged with material through pipes 1, 2 and valves 6, 7, and discharged through valves 8, 9 into chamber 5 and the pipe-line 24. Flexible-walled, annular compensator chambers 12, 13 in chambers 3, 4 are alternately connected to the suction and discharge sides of a pump 19 by a valve 16. Guide tubes 10, 11 in chambers 3, 4 receive the material and prevent it from contacting chambers 12, 13. With valves 6 to 9 in the positions shown, chamber 4 fills with water under pressure from pipe-line 24, and chamber 3 is filled with water by pumps 19 via compensator chamber 12 and a non-return valve 25. A predetermined quantity of material is then loaded into tube 10 in chamber 3, and valve 16 is operated to connect chamber 12 to the pump suction side to reduce the volume of chamber 12 by the volume of loaded material. At the same time chamber 13 is connected to the pump discharge side, and is expanded. Valves 6 and 9 are then closed, and valve 16 operated to connect chamber 13 to pump suction and chamber 12 to pump discharge. Valves 7 and 8 are held closed by the high pressure in chambers 4 and 5. The contraction of chamber 13 reduces the pressure in chamber 4 to permit opening of valve 7, while the expansion of chamber 12 increases the pressure in chamber 3 to permit opening of valve 8. The material then discharges from chamber 3 into chamber 5 and is entrained by the water in pipe-line 24. Chamber 4 is then loaded with material and the cycle repeated, valves 6 to 9 and 16 being automatically actuated by hydraulic cylinders. When the material has been discharged from chamber 3 or 4, and its associated chamber 12 or 13 has been fully expanded, water passes through non-return valve 25 or 26 to displace material-contaminated water from chamber 3 or 4. Reservoir 21 supplies water for priming pump 19 and making up losses in the system. To prevent the inner flexible wall of the compensator chamber 12, 13 from closing the supply pipe 14, 15 when it contracts, a plate with spacers is mounted on the wall, Fig. 2 (not shown). Alternatively, the inner wall may be attached to tube 10, 11.
