The calcination of the catalysts at high temperature may easily result in theformation of tetrahedral structure Mo species before sulfidation,and decrease theamount of octahedral coordination Mo species.The sinter and loss of the activecomponents would take place during the calcination at overhigh temperature. Meanwhile,the active component could react with support,thus made the activecomponents entered into support bulk phase.
