Abstract: A method and apparatus for purifying gas where gas is treated in a multistage treatment having at least two ejector stages, a motive medium including liquid, steam or gaseous agent at high pressure injected by an ejector of the ejector stage, and the gas is sucked into the same ejector and mixed with the motive medium for forming a mixture, at least a part of gas and/or liquid phase of the mixture is supplied to a second ejector stage having so that a second motive medium which includes liquid, steam or gaseous agent is injected to the ejector and the gas and/or the liquid phase is sucked into the same ejector in which the gas and/or liquid phase is mixed with the second motive medium for forming a second mixture, at least one of the mixtures includes an additive for removing impurities of the gas, and a purified gas is formed.

Abstract: The invention relates to a method and an apparatus for purifying gas, wherein the gas which includes at least tars and/or undesired hydrocarbons is supplied to a catalytic treatment reactor which has at least one catalyst zone including at least one catalyst element with a catalyst, oxygen gas is fed into the catalyst element of the catalyst zone in the catalytic treatment reactor and is supplied through the catalyst element, the gas is arranged to flow to the catalyst zone and arranged to contact with the oxygen gas and the catalyst, and a purified gas is discharged from the catalytic treatment reactor. Further, the invention relates to the use of the method.

Abstract: A method and apparatus for gasifying raw material. The method includes feeding the raw material into an upper part of a fixed-bed gasifier, introducing the raw material from the upper part of the gasifier to a pyrolysis zone of the gasifier to form the fixed-bed and pyrolyzing the raw material in the presence of pyrolysis air to form a pyrolysis product. Introducing the pyrolysis product from the pyrolysis zone to a lower part of the gasifier, introducing primary air countercurrently to the lower part, carrying out a final gasification in a lower part of the gasifier in order to form a gasified gas. Introducing the gasified gas to a catalytic oxidation part and through a catalyst layer of the catalytic oxidation part, and reforming the gasified gas by way of the catalytic oxidation in the presence of reforming air in the catalytic oxidation part, forming a gaseous product.

IPC: C10K3/02
Abstract: The invention relates to a method and an apparatus for removing impurities from a gasification gas, wherein the gasification gas which includes at least tars and/or undesired hydrocarbons is supplied to a catalytic reformer which has at least one catalyst bed, oxygen containing gas is injected onto the surface of the catalyst bed, the gasification gas is arranged to flow through the catalyst bed and arranged to contact with the oxygen containing gas in the catalyst bed, and a purified gas is discharged from the catalytic reformer. Further, the invention relates to the use of the method.
