Zusammenfassung:Zpusob výroby vodíku rozkladem vodní páry v prítomnosti pyrolýzního zbytku po zpracování odpadního polyethylentereftalátu probíhá pri teplote v reaktoru 700 .degree.C až 1500 .degree.C a tlaku 0,09 až 0,15 MPa. Vznikající plynná reakcní smes obsahuje vodík v koncentracním rozsahu 20 až 75 % a sulfan méne než 0,01 % vztaženo na objem smesi. The process for preparing hydrogen by decomposition of steam in the presence of a pyrolysis residue after processing of waste polyethyleneterephthalate takes place at a reactor temperature in the range of 700 degC to 1500 degC and a pressure in the range of 0.09 to 0.15 MPa. The generated gaseous reaction mixture contains hydrogen in the concentration range of 20 to 75 percent by volume and less that 0.01 percent by volume sulfane, based on the mixture volume.
