The fluid catalytic cracking process is responsible for about 30% of CO2 emission in a petroleum refinery. The possibility to react CO2 and coke (Reverse-Boudouard reaction - RB) during the spent catalyst regeneration in the presence of CO2 and O-2 a

The regeneration of a coked fluid catalytic cracking (FCC) catalyst under O2/He and CO2/He atmospheres from room temperature up to 1000 °C was studied using online mass spectroscopy. The catalyst was also thermally treated at temperatures between 30

Niobia-modified silica was used as support for nickel-based catalysts. Catalysts with different nickel loading were prepared by successive incipient-wetness impregnation of toluenic nickel octanoate solutions. The samples were characterised after bot

Nickel and vanadium were responsible for a great number of deactivation problems in the FCC. To understand their mutual influences, the metals were introduced by incipient wetness impregnation of organometallic compounds onto a highly dealuminated ze

The effects of the SAR (14 and 38) and of the methodology of introduction of nickel (wetness impregnation and ion exchange) on catalyst activation were investigated in Ni/USY model catalysts submitted to two activation treatments: reduction (A) and r
