摘要:
The invention relates to a novel catalyst based on zeolite, the production of that catalyst, and the use of the catalyst in a method for producing lower olefins from oxygenates and for oligomerizing olefins. The novel catalyst has a SiO2/Al2O3 weight ratio of 2 to 9, a BET surface of 250 to 500 m2/g, and an Na content under 200 ppm. The catalyst includes a crystalline alumosilicate zeolite and a binder. The catalyst is characterized in that the ratio of the peak heights of its IR absorption bands v=3610 cm−1±20 cm−1/v=3680 cm−1±20 cm−1 is greater than 1.8.

摘要:
The water turbine of the present invention includes a housing defining a generally cylindrical chamber therein defining a laterally extending opening. Rotatably positioned within the chamber is a rotor including a plurality of folding wings or vanes extending outwardly therefrom. Each vane includes a first blade section which is immovably fixed with respect to the rotor hub and a second blade section which is pivotally secured with respect to the first blade section. This pivotal movement of the second blade toward the nonpropelling side of the vane is restricted by a stop whereas pivotal movement of the second blade section toward the propelling side of the vane is made possible. A biasing device is included to urge the second blade section into contact with the stop which is the propulsion of the vane. To protect the joined connection between the first and second blade sections a covering means preferably including an expandable and contractable baffle section may be included. With this configuration the inner covering would preferably be of a resilient material to thereby comprise the biasing device. The folding wing design of the rotor allows full operational rotation thereof with the rotor extending perhaps only partially along the laterally extending opening of the housing. The rotor can be of any vertical dimension depending on the normal surrounding environment of the particular water in which a specific turbine is being positioned. In this manner a water turbine device for utilizing the kinetic energy of moving water by transferring it into electrical energy is created.

An improved revolver with a reduced barrel/cylinder gap (34) employs cylinder-chamber passages (54) through which bullets travel on route to the barrel bore (62) having diameters which are at least 0.005 inch greater than the diameter of the bullets. In this revolver the forcing cone (41) of the barrel bore (62) is at least one-half inch long and has a large-end diameter which is 0.025 to 0.035 inch larger than the bullet diameter. The cylinder/barrel gap (34) is less than 0.004 inch.
摘要:
A process for the chemical treatment of an effluent containing at least one organic compound selected from the group consisting of an organometallic compound and an organic compound containing at least one of phosphorus, nitrogen and halogen, comprising treating the effluent hydrolytically for about 20 to 200 minutes at a temperature above about 100.degree. C. under a pressure above about 2 bars and a pH of about 1 to 14. Advantageously, a catalyst comprising activated carbon or kieselguhr is added to the effluent before the hydrolytic treatment and the hydrolytic treatment is carried out in the presence of ammonia or a primary or secondary amine. The organic compound may be an acid ester, a dye, or quaternary ammonium compound, a cyanide, a nitrile, a cyanate, an isocyanate, hydrazine, an organic derivative of hydrazine, an azo compound or an organometallic compound and the effluent may be aftertreated as with hypochlorite or H.sub.2 O.sub.2.
