Abstract: A process for the production of synthesis gas from coke is described herein. The process comprises the steps of: (a) subjecting hard coal to dry pyrolysis, resulting in the production of a gas mixture containing hydrogen, methane, nitrogen and carbon monoxide as major constituents and carbon sulphides as minor constituents; (b) subjecting the gas mixture to hydrogenation at a temperature in the range of 200 to 280° C. over a sulphidic cobalt molybdenum catalyst provided on an aluminium oxide carrier material; and (c) separating the hydrogen sulphide obtained from hydrogenation from the gas mixture.

Abstract: The invention relates to an apparatus for gas scrubbing, in particular for removing CO2 from flue gas by means of amine scrubbing. The apparatus comprises a cooling stage for directly cooling and for pre-scrubbing a gas flow entering the apparatus by means of a liquid fed to the cooling stage, an absorption stage for removing at least one gas component from the gas flow by means of a scrubbing liquid fed to the absorption stage, and a post-scrubber for depleting at least one volatile component of the scrubbing liquid from the cleaned gas flow. According to the invention, the cooling stage, the absorption stage, and the post-scrubber are arranged one above the other and connected to form a washing tower.

Abstract: A method for feeding back exhaust gas from a gas turbine with a downstream waste heat boiler, wherein this exhaust gas is metered into the air inflow stream of a gas turbine, with the result that the temperature and the composition of the exhaust gas can be controlled, and in this way highly concentrated carbon dioxide (CO2) is obtained which can be injected into a storage facility, so that the balance of the carbon dioxide for the entire process can be kept low or is negligible. The temperature in the gas turbine can be lowered and the proportion of carbon dioxide in the exhaust gas can be considerably increased. After combustion has taken place and heat has been exchanged, gas washing is possible, carbon dioxide can be recovered and, the proportion of free oxygen in the exhaust gas can be lowered.

Abstract: The invention relates to a method and an installation for producing sulfuric acid. First of all, a product gas flow (5) containing sulfur dioxide is produced. The product gas flow (5) is supplied to a reaction chamber (1). A catalyst (3) is located in the reaction chamber (1). In the presence of the catalyst sulfur dioxide reacts to form sulfur trioxide. In further parts of the installation the resulting sulfur trioxide is converted to sulfuric acid. According to the invention, an oxidizing gas flow (6) is supplied to the reaction chamber (1) alternately with the product gas flow (5).
