Continuous pyrolysis of carbonaceous materials with model gasification of the solid product
Kříž, Vlastimil; Káš, Václav; Brožová, Zuzana
2008 - English
Samples of lignite from Jiří Mine alone and its mixtures (30%) with waste tire-rubber, Forsan (ABS) and cellulose were pyrolyzed on a rotary kiln at a temperature of 900°C. The solid product was gasified by steam and carbon dioxide. Vzorky samotného hnědého uhlí z dolu Jiří a jeho směsi (30%) s pneu-pryží, Forsanem (ABS), a celulózou byly pyrolyzovány v rotační peci při teplotě 900°C. Tuhý produkt byl zplyňován vodní parou a oxidem uhličitým.

Hydrogen - the product of coal thermal conversion
Kříž, Vlastimil; Brožová, Zuzana
2007 - English
Hydrogen fixed in the coal structure was converted to gaseous form using two-stage pyrolysis. The hydrogen volume in the pyrolytical gas strong increased along with the temperature in the cracking module. There was verified the possibility to obtain hydrogen by thermal decomposition of coal pyrolysis volatile products. Vodík vázaný ve struktuře uhlí byl získán v plynné formě pomocí dvoustupňové pyrolýzy. Objem vodíku v pyrolyzním plynu strmě rostl souběžně se zvyšující se teplotou ve štěpném modulu. Byla ověřena možnost získat vodík termickou degradací těkavých produktů z pyrolýzy uhlí.
