    Abstract: The invention relates to a method for producing carbon membranes suitable for separating gases, comprising the steps of a) coating a porous substrate with a solution of at least one organic polymer that can be transformed into a carbon membrane by pyrolysis, b) drying the polymer coating on the porous substrate by removing the solvent, and c) pyrolysing the polymer coating on the porous substrate to form the carbon membrane which is suitable for separating gases, it being possible to carry out each of steps a) to c), or the sequence of steps a) to c), multiple times, and the pyrolysis in step c) taking place at a temperature that is higher than the stoving temperature of the porous substrate.

    Abstract: The invention proposes a method for producing polyether polyols by converting the following reactants: a) one or several alkylene oxides and, optionally, carbon dioxide, as well as b) one or several H-functional starting materials in the presence of a catalyst, having several micro-structured layers, A and B, arranged parallel to one other in a reaction unit such that each layer displays a multiplicity of channels arranged parallel to one another, which form a continuous flow path from one side of the plate to the opposite side of said plate, characterized by the fact that, a distribution device is proposed at the end of layer A for the channels of said layer to supply the reactants as well as the catalyst, and a collection device is proposed at the other end of said layer for the reaction mixture.
