Abstract: The present invention relates to a device for treatment of material transported through the device comprising at least one porous element consisting of solid, for example metallic, structure which allows cross-flow of the material through the porous element. A device in accordance with the invention is particularly useful as mixer or heat exchanger or to carry out chemical reactions under homogenous and heterogeneous conditions. Such a device hereinafter also referred as reactor may comprises a tube (1) having a cylindrical wall (2) with one inlet end (3) and one outlet end (4). Arranged in the tube (1) is at least one cylindrical porous element (5) consisting of solid metal structure, wherein said porous element (5) comprises a plurality of hollow spaces that are connected to each other and form an interconnected cavity network and wherein the at least one porous element (5) and the cylindrical wall (2) are made in one piece. The porosity ? of the at least one porous element (5) is between 0.8 and 0.95.

Abstract: A multi-chamber reactor (1) comprises an outer chamber (2) and at least one inner chamber (3), wherein the at least one inner chamber (3) is formed by a reactor/liner (6), which is closed by a closure (7), in particular a septum or a disk that can be penetrated with a needle, and the outer chamber is an autoclave, wherein the autoclave is composed of an autoclave body (4) and an autoclave cover (5), wherein the autoclave cover (5) has at least one first opening (8) for a needle (9), and preferably a second opening (10), which opens into the outer chamber. Said multi-chamber reactor (1) is suited for carrying out reactions with positive or negative pressure and under complete exclusion of air and/or moisture.
