Co-processing bio-oils with conventional hydrocarbon feedstocks in the FCC process in refineries is an interesting option for the production of fuel and petrochemical raw materials. The previous upgrading of bio-oils with a thermal treatment allows decreasing the content of coke precursors and improving their processing characteristics. The co-processing of crude and upgraded bio-oil with vacuum gas oil (VGO) was studied in a CREC Riser Simulator reactor under typical commercial FCC conditions. It was observed that the addition of oxygenated feedstock (e.g. up to 5 %wt.) did not affect the product distribution significantly. Coke yields in co-processing were even lower than in the conversion of VGO alone, due to the simultaneous addition of water.
