Abstract: The invention relates to a method and apparatus for producing a product gas from a feed comprising at least carbon dioxide, hydrogen and hydrocarbons. The feed is supplied to a reactor comprising a catalyst, the catalyst is heated electrically, the feed is supplied through the catalyst and a reaction is performed at least between carbon dioxide (CO2) and hydrogen (H2) in the presence of the catalyst in the reactor, and the product gas comprising at least carbon monoxide (CO) and hydrogen (H2) is formed in the reactor. Further, the invention relates to the use of the method.

Abstract: The invention relates to a method for forming a porous structure with a catalyst, wherein an organic space holder material is coated with at least one catalytic material to form a coated organic space holder material, the coated organic space holder material is mixed with a carrier material to form a mixture, and the organic space holder material is removed and the mixture in sintered to form the porous structure with the catalyst. Further, the invention relates to the porous structure and use of the porous structure obtained by the method.

Abstract: The invention relates to a reactor and a method for producing a product, wherein the reactor comprises an inner part which is formed at least in part from a porous material comprising a catalyst and in which at least one reactant is arranged to flow into the inner part and after that through the porous material to form a product, a shell structure which surrounds the inner part, a space between the inner part and the shell structure in which the product formed from the reactant in the porous material is arranged to flow out from the reactor, and a heating device for heating electrically the porous material. Further, the invention relates to the use of the reactor.

Abstract: The invention relates to a method and a process arrangement for producing a solid product, e.g. biochar, by means of a gasification. Bio-based raw material (1) is gasified for forming a product gas (4) and a solid co-product (5) in a gasifier (2), and a gasification temperature is arranged to temperature of 750 - 850° C. for increasing a yield of the solid co-product. Further, the invention relates to the use of the solid co-product.

Abstract: A method and apparatus for producing carbon monoxide, wherein the carbon monoxide is formed from a gaseous feed which includes at least carbon dioxide. The method includes supplying oxygen to a carbon dioxide stream for forming a carbon dioxide based mixture, supplying the carbon dioxide based mixture to a hydrogen based stream to form the gaseous feed, supplying a hydrocarbon containing stream to the hydrogen based stream before the supply of the carbon dioxide based mixture, feeding the gaseous feed into a reactor which includes at least one catalyst, treating the gaseous feed by partial oxidation in the reactor so that carbon dioxide reacts with hydrogen in the reactor in presence of oxygen and heat is formed during the reaction, and recovering a product composition including at least carbon monoxide and hydrogen from the reactor.
