Limitations in the energy balance when VGO/aqueous bio-oil mixtures are co-processed in FCC units

The effect on the energy balance of a FCC unit after co-feeding aqueous fraction bio-oil together with vacuum gas oil (VGO) has been studied. simulation program considers interdependency relationship between reaction and regeneration sections in unit, where heat coke combustion to sustain requirements preheat vaporize feedstock as well endothermic cracking reactions. deposited an equilibrium commercial catalyst various bio-oil/VGO mixtures at 530 °C, relationships 3 6 CREC Riser Simulator laboratory reactor, was investigated by means thermogravimetric analysis (TGA) differential scanning calorimetry (DSC). Results showed that from is not enough provide needed when amount larger than 5 wt%, mainly due high content water lower formed co-processing, compared VGO alone.
