Abstract

The results are presented of an experimental investigation of the kinetics of evolution of C n H m , CH4, CO and H2 in the course of shale thermal decomposition. The experiments were carried out with a complex experimental set-up consisting of a derivatograph, a chromatograph and a spectrophotometer, with shale samples of different fractions from different seams of basic commercial deposits. In spite of the differences in the sites of taking the samples and in their characteristics, the reaction rate curves for each gas are close to one another.

Zusammenfassung

Ergebnisse einer experimentellen Untersuchung der Kinetik der Freisetzung von C n H m , CH4, CO und H2 im Verlaufe der thermischen Zersetzung von Schiefern werden mitgeteilt. Die Versuche wurden mit einer komplexen, aus einem Derivatograph, einem Chromatograph und einem Spektrophotometer bestehenden Ausrüstung vorgenommen. Untersucht wurden Schiefer von verschiedenen, kommerziell abgebauten Lagerstätten. Obwohl sich die Schieferproben hinsichtlich der Lage und der Charakteristik des Vorkommens unterscheiden, verlaufen doch die Reaktionsgeschwindigkeitskurven für jedes Gas nahezu gleich.

Резюме

Представлены резуль таты эксперименталь ного исследования кинети ки выхода С n Н m , СН4, СО, H2 при термическ ом разложении сланца. Опыты проводились на компл ексной экспериментальной у становке, состящей из дериватографа, хрома тографа и спектрофот ометра, с образцами сланца ра зличных фракций из ра зличных пластов основных про мышленных месторождений. Показ ано, что кривые скорос ти реакции для каждого газа близ ки друг к другу независимо от различ ий в местах отборов об разцов и их характеристиках.
