The invention relates to the use of a reactor, methods, and devices for the quantitative recovery of molecular hydrogen from solid, liquid, or gaseous substances which contain hydrogen and which have heteroatoms, as well as to reactors. In this case, the reactors have material containing chromium. The subject matter of the invention also includes the use of the reactor, the method, and the device for the compound-specific or component-specific measurement of the isotope ratio (δ2H) of hydrogen using online apparatuses.
The method according to claim 38 wherein the zone with temperatures above 1100° C. is generated in the reactor to pyrolize the substances.

The method according to claim 38, characterized in that silver wool is arranged in a first region of the reactor, as a halogen trap, where there is a temperature zone between 500° C. and 800° C. during pyrolysis due to the temperature zone generated above 1100° C.
The method according to claim 38, characterized in that the solid, liquid, or gaseous substances from which the molecular hydrogen will be recovered are separated into their components by means of gas chromatography prior to entry into the reactor.

A method for the quantitative recovery of molecular hydrogen from solid, liquid, or gaseous substances which have heteroatoms, using a pyrolysis reactor with material containing chromium, characterized in that a zone with temperatures above 1100° C. is generated in the pyrolysis reactor, in which a reactive chromium layer of the material containing chromium of the pyrolysis reactor is at least partially arranged.
(canceled)
A pyrolysis reactor for the quantitative recovery of molecular hydrogen from solid, liquid, or gaseous substances which have heteroatoms, having pure chromium as the material, the same consisting of chromium powder or chromium granulate with a diameter of 0.05 mm to 5.0 mm.
A pyrolysis reactor for the quantitative recovery of molecular hydrogen from solid, liquid, or gaseous substances which have heteroatoms, having material containing chromium, the same made of chromium and other heat-stable materials which do not contain any hydrogen and/or do not react with molecular hydrogen at temperatures above 1100° C.
