The invention relates to a process for the electrochemical separation of hydrogen from a hydrogen-comprising reaction mixture R by means of a gastight membrane-electrode assembly comprising at least one selectively proton-conducting membrane and at least one electrode catalyst on each side of the membrane, where at least part of the hydrogen present in the reaction mixture R is oxidized to protons over the anode catalyst on the retentate side of the membrane and the protons are, after passing through the membrane to the permeate side,

Method for electrochemically removing hydrogen from a reaction mixture

The present invention relates to a process for converting aliphatic hydrocarbons having 1 to 4 carbon atoms to aromatic hydrocarbons in the presence of a catalyst under nonoxidative conditions, wherein at least some of the hydrogen formed in the conversion electrochemically removed is by means of a gas-tight membrane-electrode assembly.

Process for converting natural gas to aromatics with electrochemical removal of hydrogen

A process for preparing C-C-oxygenates from a reactant stream A which comprises essentially a C-C-alkane or a mixture of C-C-alkanes, by

The invention relates to a process for converting aliphatic hydrocarbons having from 1 to 4 carbon atoms into aromatic hydrocarbons, which comprises the steps:

Method for reacting natural gas to aromatics while electrochemically removing hydrogen and electrochemically reacting the hydrogen water

A process for preparing acrylic acid from ethanol and formaldehyde, in which, in a reaction zone A, the ethanol is partially oxidized to acetic acid in a heterogeneously catalyzed gas phase reaction, the product gas mixture A obtained and a formaldehyde source are used to obtain a reaction gas input mixture B which comprises acetic acid and formaldehyde and has the acetic acid in excess over the formaldehyde, and the formaldehyde present in reaction gas input mixture B is aldol-condensed with acetic acid present in reaction gas input mixture B to acrylic acid under heterogeneous catalysis in a reaction zone B, and unconverted acetic acid still present along-side the acrylic acid target product in the product gas mixture B obtained is removed therefrom, and the acetic acid removed is recycled into the production of reaction gas input mixture B.

Process for preparing acrylic acid from ethanol and formaldehyde

The present invention relates to a process for converting aliphatic hydrocarbons having 1 to 4 carbon atoms to aromatic hydrocarbons, comprising the steps of:

Process for converting natural gas to aromatics with electrochemical removal of hydrogen to generate electrical power and obtain hydrogen

A process for removing sulfur compounds from a hydrocarbonaceous gas mixture, which comprises contacting the hydrocarbonaceous gas mixture with an adsorber material comprising copper oxide on magnesium silicate as support material.
