Estudio de la reacción de cloración de la circonia en presencia de carbono: desarrollo de un sistema termogravimétrico especialmente adecuado para el estudio cinético de reacciones de cloración de óxidos

Abstract: El objetivo de este Trabajo de Tesis fuá desarrollar un Sistema Termogravimétrico, adecuado para el estudio de reacciones de cloración, y aplicarlo al estudio de la cinética de la reacción de CI2 con C y ZrO2; reacción que conduce a la formación de ZrCI4; producto de interés en la industria nuclear. El diseño, construcción y calibración del Sistema Termogravimétrico, construido sobre la base de una electrobalanza Cahn 2000, fue una parte muy importante de la Tesis. En la construcción del Sistema Termogravimétr… Show more

“…17 The suitable procedure to determine exactly the reaction zero time in the chlorination of solids using the TG system of this study has been described elsewhere. 18 The ilmenite mass, as it was chlorinated, was thermogravimetrically monitored at regular time intervals of 1 s. The mass loss, DM, was determined from these measurements as follows: DM5M i 2M t , where M i and M t refer to initial ilmenite mass and ilmenite mass at time t respectively. The conversion degree a was defined as…”

“…15,16 It is well known that the rate of a chemical reaction involving a solid and a gas tends to be less influenced by mass transfer processes at lower temperatures, small sample amount and high flowrates. 15,18,19 The purpose of this paper is to study the reaction stages of the chlorination of a Venezuelan ilmenite, in order to determine the pathways and kinetics parameters. Reaction temperatures ranging from 600 to 950uC were chosen for studying the direct chlorination of ilmenite.…”
