Abstract
The gasification with steam of a bituminous coal from Peñarroya (Cordoba, Spain) (H—O) and of several samples prepared from either by acid treatment (H—H, H—N, H—F and H—F(3)) or by thermal treatment (H—O—C) was studied under both dynamic and isothermal conditions (10 deg/min and 40 min at 1000°).
It was found that only for the samples prepared by hydrofluoric acid treatment, H-F and H—F(3), did the gasification effected under such experimental conditions take place in a complete manner.
Zusammenfassung
Die Dampfvergasung von bituminöser Kohle (H—O) (Penarroya, Cordoba, Spanien) und von daraus durch Säurebehandlungen (H—H, H—N, H—F und H-F(3)) oder thermische Behandlung (H—O—C) hergestellten Proben wurde unter dynamischen und isothermen Bedingungen (10 °/min und 40 min bei 1000°) untersucht. Es wurde festgestellt, daß nur die durch Flußsäurebehandlung hergestellten Proben (H—F und H—F(3)) unter den experimentellen Bedingungen vollständig vergasbar sind.
Резюме
В динамических и изот ермических условиях (10°/мин и 40 мин для 1000°) ихуч ена газификация водяным паром битуминозных у глей месторождения Пенар оя (Испания) и некоторых образцов, п олученных из них кисл отной или термической обработ кой. Установлено, что только в случает о бразцов, полученных о бработкой фтористоводородной кислотой, газификация протека ет полностью при данн ых экспериментальных у словиях.
