VARIABLE HYDROPYROLYSISREACTIVITY OF KEROGEN FROM TARFAYA OIL SHALE DEPOSIT (MOROCCO). MODELING IN HETEROGENEOUS KINETICS

Abstract

Hydrogen treatment of oil shale kerogen is highly beneficial, firstly because it improves the yield of oil produced compared with pyrolysis, secondly because the oils produced are of light quality and thirdly because the kinetics of this heterogeneous reaction are simpler (A.Attaoui: 2023). The latter, often discussed in true thermogravimetry (dynamic regime), can be adapted to several mathematical models for processing values.In this work we are going to follow this primary hydropyrolysis reaction in the dynamic regime using thermogravimetry, and we are going to develop a method for processing the experimental values in order to access the energies of the different oil shale layers at different heating rates.The aim of this study is to establish the activation energy balance for the different layers of the Tafaya primary hydropyrolysis deposit. We used the Red-Croft thermobalance to carry out these reactions. We note the close dependence between the experimental technique, the data processing model and the activation energies search for.
