Conceptual Study of Process Intensivation of Existing Sugar Cane Biorefinery by Biomass Residue Pyrolysis and Off-Gas Syngas-Fermentation

Short Introductive summary

Within a Brasilian-German cooperation network, the entities IPT (Instituto de pesquisas tecnológicas) and KIT (Karlsruhe Institute of Technology) are working on the process development around biomass processing. We present a conceptual study on process intensification in the brasilian sugarcane industry, with the scientific issue: How can we intensify existing processes to deliver more biogenic carbon from field to (exportable) products? We compare the extension of the state-of-the-art sugarcane biorefinery with a pyrolysis unit and a syngas fermentation unit, with main target to identify the carbon-to-product potential and respective costs. The potential of extending the existing sugarcane biorefinery in Sao Paolo state by two new technologies, is displayed in marginal abatement cost curves.
