Abstract: An 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 producing a hydrocarbons product from plastic containing material, wherein the plastic containing material is subjected into a pyrolysis reactor, steam is fed into the pyrolysis reactor, and the plastic containing material is pyrolyzed in the presence of the steam by using a catalytic pyrolysis with a mildly acidic catalyst comprising at least aluminium oxide, aluminium silicate, zirconium oxide or their combinations to convert the plastic containing material to the hydrocarbon product comprising wax. Further, the invention relates to the use of the product obtained by the method.
