Abstract
Catalyzed hydropyrolysis has been the subject of several studies. These studies are based on thermal reactions under hydrogen aided by catalysts that facilitate the diffusion of heat and matter through their pores. Supercritical extraction (J. Triday and J.M. Smith. 1988) of solid compounds are reactions influenced by interparticle position, pore diffusion, interphase mass, heat transfer and flow in the differential reactor. Zeolites include Al2O3 and Cr2O3.In this study, we monitored the effects of these zeolites during the decomposition of Tarfaya oil shale (Morocco) under dynamic hydrogen conditions (21°C/min), using thermogravimetry and calorimetry. The results obtained using Al2O3 (alumina) can be summarized as an increase in the rate of pyrite conversion, invariability for calcite and dolomite, and a decrease for quartz, kaolinite and chlorine compounds. When chromium oxide Cr2O3 was used, however, energetic deactivation was observed. The techniques used in this study include dispersive XRD coupled with scanning electron microscopy, thermogravimetry with amplified differential calorimetry (DCA), a precise and reproducible calorimetric technique.
