Abstract
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.
Claims17
A method for the quantitative recovery of molecular hydrogen from a sample of solid, liquid, or gaseous substances which have heteroatoms, comprising:
- introducing the sample, via an inlet, into a pyrolysis reactor with material containing chromium;
- performing pyrolysis of the sample to form hydrogen, 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 within the zone and adjacent to a quartz layer;
- and
- providing the hydrogen via an outlet of the pyrolysis reactor, the reactive chromium layer of the material containing chromium arranged between the inlet and the quartz layer, and the quartz layer arranged between the chromium layer and the outlet of the pyrolysis reactor, the quartz layer including quartz wool, and a layer of chippings arranged next to the quartz layer, the layer of chippings including one or more of:
- quartz, ceramic, or glassy carbon.
