Abstract: A process for hydrogenation of oxygen-containing organic products, oil refinery products or mixtures thereof, wherein the process comprises bringing the organic products, oil refinery products, or mixtures thereof into contact with a catalyst according to claim 1 in the presence of hydrogen gas at a temperature in the range of 200 to 500° C. and at a pressure in the range of 10 to 1000 bar.

Abstract: The catalyst comprises at least a metal component and at least a non-metallic conducting component as supplement component. The metal component generally contains one or more metals of the groups VIb, VIIb or VIIIb of the periodic table. The supplement component is e.g. a conducting carbon material like graphite, a conducting polymer or a conducting metal oxide. Preferably it is hydrophobic or made hydrophobic. The catalyst is used for hydroprocessing of bio-feedstock like vegetable oils to produce fuels, which are aliphatic hydrocarbons comparable to conventional fuel from mineral oil.

Abstract: The device continuously determines the carbon monoxide content of air in the emission and immision range, and comprises an electrochemical cell including an acid electrolyte with a cathode and a diffusion anode in the electrolyte, the anode being depolarizable by carbon monoxide in the acid electrolyte. A current measuring device measures the current between the anodeand the cathode responsive to detection of a gas containing carbon monoxide effective on the diffusion anode. The cathode is made of an unpolarizable material whose oxidation potential is so high that no oxygen reduction takes place at the anode. The cell functions without an external current source, and the current measuring device is connected to directly across the anode and the cathode. The cathode contains substances with an oxidation potential of from 1000 to 1300 millivolts relative to a hydrogen electrode in the same electrolyte.

Abstract: An electrochemical measuring cell for the continuous measurement of sulfur dioxide content of the air in emission and immission areas, comprises a cell housing which has a test gas cell chamber therein for the connection for circulating the gas to be tested into the chamber. The chamber also contains a diffusion electrode which serves as an anode and which is made up of a reversible organic redox system. The cathode comprises an active mass having a redox potential higher than the redox potential of the anode. An immobilized electrolyte is disposed between the anode and the cathode and the anode and cathode are connected to a device for measuring the short circuit current. The diffusion electrode is manufactured from a mixture of chloranil and sodium tungsten bronze which is pulverized in a ball mill for sixteen hours and mixed with a polyethylene powder and sodium sulfate and is then compressed.
