A method of transforming a normally gaseous composition containing at least one hydrogen source, at least one oxygen source and at least one carbon source into a normally liquid fuel, wherein said gaseous composition consists at least in part of carbon dioxide as said carbon source and said oxygen source, and of methane as said hydrogen source and as a second carbon source; the method comprising the steps of feeding the composition into a reactor including a first electrode means, a second electrode means and at least one layer of a normally solid dielectric material positioned between the first and the second electrode means; submitting the composition within the reactor in the presence of a normally solid catalyst to a dielectric barrier discharge, wherein said normally solid catalyst is a member selected from the group of zeolites, aluminophosphates, silicoaluminophosphates, metalloaluminophosphates and metal oxides containing OH groups; and controlling the dielectric barrier discharge to convert the gaseous composition into the normally liquid fuel.

Fuel synthesis

A method of transforming a normally gaseous composition consisting essentially of methane into a material comprising a major portion, at least, of hydrocarbons containing at least two carbon atoms; the method comprising the steps of feeding the composition into a reactor including a first electrode means, a second electrode means and at least one layer of a normally solid dielectric material positioned between the first and the second electrode means; submitting the composition within the reactor in the presence of a normally solid catalyst to a dielectric barrier discharge; and controlling the dielectric barrier discharge to convert the normally gaseous composition into the material comprising a major portion, at least, of the hydrocarbons containing at least two carbon atoms.

Process and device for the conversion of a greenhouse gas

A depassivation layer is produced on an electrode for an electrochemical cell by applying one or more layers of a metal salt solution, containing the elements to be applied, to the substrate (1) which is to be coated and is in the form of a porous plate, by means of rolling an elastic roller (2) over the substrate, with the insertion of a solution carrier (3) in the form of felt or paper, and then drying the layer and subjecting it to a chemical/thermal treatment in air (heat treatment at 450.degree. C.). Good depassivation layers with a relatively small noble metal content can be produced in this way. The depassivation layer which, in the form of a homogeneous film, is at least partially coherent contains, as a finely divided, sub-microscopic mixture, electronically conductive sub-oxides/oxides of the substrate (1) in addition to noble metals/noble metal oxides, and it can also contain further components, such as SnO.sub.2.

A method for continuous coating of a solid electrolyte (3) with a coating comprised of a catalytically active metal, comprising impregnating the solid electrolyte (3) (present in the form of a film comprised of a plastic polymer) with a solution of a metal salt, and electrolyzing the metal salt in a plurality of passes of the solid electrolyte (3) between two rolls (4, 5) which rolls serve as electrodes, in a water bath, wherewith at first the speed of advance of the solid electrolyte film is a relatively high value of 20 to 30 cm/min and then a lower value of 1 to 2 cm/min, and wherewith the linear current density in the line of contact between the rolls (4, 5) and the solid electrolyte (3) is at least 830 mA/cm.

An electrically conductive layer on a solid-body electrolyte (1) is produced by swelling and impregnating an organic ion exchange material (2) with a metal salt solution, drying, converting the metal ions in a gas stream to finely distributed particles (3) which are in electrical contact with one another, renewed swelling in a solvent, converting into a brushable paste and applying same to the surface of the solid-body electrolyte and drying. Preferred embodiment: solid-body electrolyte (1) and ion exchange material (2) made of polymers containing sulphonic acids; and conductive particles (3) made of platinum metals or oxides thereof, in particular ruthenium as electrocatalyst.
