Abstract: A process is described for generating hydrogen through the oxidation of fuels that contain chemically bound hydrogen, in particular hydrocarbons, having the following process steps: a) introducing the fuel (1) as well as the oxidation agent (2) into a reactor (3) having a porous material (4′) that is embodied in such a way that flame propagation in a direction opposite the direction of flow is prevented, and b) reacting the fuel with the oxidation agent in partial oxidation so that hydrogen is obtained in gaseous form.

Abstract: A multiple tube bundle heat exchanger includes axially opposite tube plates, a housing, and a plurality of tube bundles disposed between the tube plates. Each of the tube bundles is an independent tube bundle subassembly forming an integral unit having at least one heat exchanger tube with two axial tube ends. The subassembly is made from the exchanger tube and respective tube plates fastened to the two axial tube ends. The housing has a casing part defining a interior and having two axial housing ends with flanges, removable head pieces respectively disposed at the two axial housing ends to be fastened to the flanges, and partitions subdividing the interior into chambers. The number of chambers corresponds to a number of tube bundles. Each of the chambers receives one of the tube bundles. The tube plates and head pieces respectively form seals, and the tube plates delimit distributor, collecting, and/or transfer chambers formed in the head pieces.

Abstract: Mixtures containing at least one functionalized low-molecular rubber A, at least one cross-linking agent B having groups which are reactive with respect to the functional groups of the rubber A, accelerators/catalysts C for the cross-linking reaction between A and B, possibly reactive diluents D, vulcanization chemicals E, and also fillers F and auxiliary substances G, with at least one of the average functionalities of the constituents A and B being at least 2, and their use as anti-corrosive coating agents.
