Resumen:
The effect on the energybalance of a FCC unit after co-feeding the aqueous fraction of a bio-oiltogether with a vacuum gas oil (VGO) has been studied. The simulation programconsiders the interdependency relationship between the reaction andregeneration sections in the unit, where the heat of coke combustion has tosustain the energy requirements to preheat and vaporize the feedstock as well asthe endothermic cracking reactions. The combustion of coke deposited on anequilibrium commercial FCC catalyst in cracking various bio-oil/VGO mixtures at530 ◦C, with catalyst to oil relationships between 3 and 6 in a CREC RiserSimulator laboratory reactor, was investigated by means of thermogravimetricanalysis (TGA) and differential scanning calorimetry (DSC).Results showed that the heatfrom coke combustion is not enough to provide the energy needed in the unitwhen the amount of bio-oil in the feedstock is larger than 5 wt%, mainly due tothe high content of water in the aqueous fraction of the bio-oil and to thelower heat of combustion of the coke formed in co-processing, as compared tothe VGO alone.
