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: Method for manufacturing a pipe for a pipeline, wherein at least part of the pipe is manufactured by additive manufacturing process, wherein at least one space for an ultrasonic transducer is formed inside the material of the pipe during the additive manufacturing process. The additive manufacturing process is interrupted before the space in closed, and the ultrasonic transducer is inserted in the open space, and the additive manufacturing process for manufacturing the pipe is continued. The invention also relates to such a pipe.
