Title : Technology Roadmap: Trends in the use of fluidized bed catalytic cracking catalysts in bio-oil co-processing in refineries


The need to decarbonize the energy matrix based on fossil fuels has led different segments to seek alternatives through the use of biofuels. The present work proposes, using the prioritization technique called Roadmap, to analyze the trend regarding the use of catalysts in different operations carried out in refineries (Fluid Catalytic Cracking, and others), for the co-processing of renewables (bio-oil) in their units. Based on the technique, maps of the short-term situation will be shown based on the analysis of approved patents and what has already been carried out, a map with the medium-term trend, based on patent applications and a final long-term map considering the information extracted from articles available on different platforms (Scopus, Science Direct, among others). The study will consider a time span of 10 years. The roadmap methodology consists of temporal assessment, enabling the identification of associations between different institutions (companies and universities or research centers). It uses, to analyze the taxonomy identified when reading all the material, allowing to evaluate the state of the art in terms of types or developments of catalysts used and types of processing, whether co-processing occurs in fluid catalytic cracking (FCC), in the hydro thermal processing (HDT) or catalytic hydrocracking (HCC). Preliminary results indicate that in terms of refining processing, FCC has been the most used step, whether in bio-oil co-processing or in biomass cracking. Next, HDT is the second most used option, as for the catalyst, ZSM5 has been most cited in the references analyzed so far.

Audience Takeaway Notes: 

  • Knowledge of technology trends in the short/medium and long term helps guide research in the line of catalysts for the co-processing of renewables in catalytic cracking.
  • For those who work in the processing of petroleum and derivatives, it will show aspects related to operational conditions and co-processing yields, for researchers, aspects related to the type of catalyst used.
  • The present work is related to a master's thesis, its recommendations serve as a basis for new research in the segment.
  • The work does not present practical solutions, it only indicates the direction to be considered in the line of catalysts for the co-processing of renewables in oil refining units.
  • The work will provide information that can help study the difficulties identified in the co-processing of renewables in refineries.
