摘要

The basic properties of Moroccan oil shale were analyzed in this paper. Pyrolysis experiments at different heating rates were carried out by thermogravimetry. The results show that the pyrolysis process of Moroccan oil shale can be divided into three steps. A shrink-nuclear model that considers the internal heat transfer of particles was established, which can better simulate the pyrolysis process of oil shale. The pyrolysis kinetic parameters of Moroccan oil shale were calculated based on heat transfer data and basic physical parameters. The results show that the apparent activation energy of the reaction is around 120 kJ/mol, and the apparent frequency factor is around 2×1014 mol/(s?m2).
