specifications), additional water production, deactivation of downstream catalytic units (due to trace oxygenates), and others. The specific problems experienced are dependent on the type of bio-based feedstock, its preparation methods, its level of use in the FCC, and a variety of other operational choices on the FCC. Summary Decarbonisation of refining processes is expected to be an important theme for the refining industry over the next several decades. While many companies are seeking entry into alternate energy value chains to achieve their decarbonisation goals, there are significant gains in decarbonising the refining system that are possible today. Using bio-based feedstocks as a decarbonisation lever is one of the most effective methods to address emissions – especially Scope 3 downstream emissions. Bio-based feedstock co-processing in the FCC has been employed around the world by refiners and is expected to continue to grow over time. Grace has supported refiners by leveraging our laboratory evaluation capabilities, including

our unique DCR Pilot Plant technology, for qualifying schemes to co-process bio-based feedstocks. Additionally, Grace’s Global Customer Technology team has built expertise in the adaptations that are necessary for the FCC to enable bio-based co-processing. With the use of these resources, we have helped refiners uncover potential issues associated with co-processing and have additionally helped refiners select and process the most appropriate (and avoid problematic) bio-based feedstocks to meet their processing goals.
