Investigação do mecanismo de desvolatização de particulas de xisto

TL;DRAbstract

Oil shale, the Jargest reserve of fossil fuels in the world, has been the subject of rnany investigations.These investigations has involved studies related to kinetic models, as well as heat and mass transfer regarding the pyrolysis reaction.Due to oil shale complex strnctnrea sedimentary rock comprising organic matter, named kerogen, scattered il an inert matrixthe studies have diverged about the pyrolysis or devolatilization mechanism.Most researches indicate the mechanism follows the shrinking core model (SCM) or the homogeneous model.As the devolatilization mechanism is important to the design of Pyrolysis reactors, the objective of the present work was to study this mechanism.In order to do that, parallelepipedic oi! shale particles, measuring 0.06 m x 0.04 m x 0.03 m, were partially pyrolyzed in a muffie finnace under inert atmosphere.Subsequently, the particle was severed to expose an inner cross section.Samples were collected and submitted to thennogravimetric analysis (TGA) to
