The production and consumption of transportation fuels is one of the major contributing factors for global greenhouse gas (GHG) emissions. It is considered that biomass derived fuels from renewable sources have the potential to help reduce GHG emissions and other environmental impacts provided that they are produced in a sustainable way based on their life cycle assessment.To diversify energy supply and to reduce GHG emissions, many countries have implemented mandatory regulations whereinthe total fuel products must contain certain percentages of biofuels or renewable products.Co-processing petroleum with biomass derived feedstocks offers a number of advantages since it uses existing refining configurations, processes and technologies,and needs little or no extra capital investment. In addition, it has the potential to generate synergies between aromatic petroleum feedstocks—especially Canadian oil sands derived crudes—and paraffinic biomass feedstocks for improved fuel quality and product yields. Therefore, co-processingis one of the most attractive and practical options for petroleum refineries to implement in order to meet government regulations and engine fuel standards. However, technological and operational challenges are expected and need to be addressed in actual implementation and operation of co-processing. This study presents a great effort to address some of these challenges.
