    摘要: A catalyst for decreasing the content of nitrogen oxides in flue gases. The catalyst contains at least one of the metals titanium, zirconium, vanadium, tungsten, molybdenum, or cerium in the form of one or more of their oxides combined with a silicate with a three-layer structure (three-layer silicate) which is or comprises talc. The three-layer silicate is preferably acid-activated while essentially retaining its crystalline layer structure and being not yet X-ray amorphous. The acid activation increases the BET surface area at least 15% and preferably at least 50% in terms of the BET surface area of the talc before acid activation. The atomic ratio of the silicon in the talc to the metal in the oxide is from 0.2 and 50 and preferably from 0.4 to 25.

    摘要: A process for the production of olefins from synthesis gas comprises a first synthesis stage in which a mixture of methanol and higher alcohols are formed from a synthesis gas comprising hydrogen and carbon monoxide. The catalyst for the first synthesis stage comprises the oxides of copper and zinc in intimate association with each other and a promoting compound selected from the group consisting of chromium, cerium, lanthanum, manganese, thorium, and an alkali metal. The materials from the first synthesis stage are separated into a gas phase and a liquid phase. Thereafter the methanol is separated from the higher alcohol fractions. The higher alcohols are then subjected to dehydration in a dehydration stage which comprises passing the higher alcohol fraction over an alkalized dehydration catalyst at a pressure in the range of 0.5-1 bar and a temperature in the range of 350.degree.-500.degree. C. Thereafter the olefins produced by the dehydration of the higher alcohols are separated into the olefinic and non-olefinic materials. Preferred dehydration catalysts include alkalized aluminum oxide and alkalized calcium phosphate.

    摘要: The present invention teaches a method for applying an anti-reflection coating to solar cells whereby the coating is interdispersed among the cell's electrodes on the cell's junction surface. The method includes coating the solar cell's surface with an anti-reflection layer, selectively etching a pattern through the anti-reflection layer, which corresponds to the desired electrode pattern and electrolessly plating a layer of nickel onto the cell's surface.

    摘要: A diplexer for a reflector antenna includes a common circular signal waveguide to transmit and receive signals. The signal waveguide includes first and second ends with a common port provided at the first end. A waveguide arrangement is disposed coaxially relative to the signal waveguide in the region of the second end of the signal waveguide. A cylindrical coupler section is disposed between the first and second ends of the signal waveguide, and connects the waveguide arrangement to the common signal waveguide. In order to create a first and second coaxial waveguide port, the waveguide arrangement includes a first circular waveguide, an inner conductor is disposed inside, in which a first signal can propagate when the diplexer is operating, and a second circular waveguide, surrounding the first waveguide, in which a second signal can propagate at a lower frequency than the first signal when the diplexer is operating.
