TECHNOLOGY OPTIONS FOR THE FUTURE SUGARCANE BIOREFINERIES

Seabra, Joaquim E. A. ; Macedo, Isaías Carvalho

Resumo:

A biorefinery can be defined as an integrated complex that makes a variety of products (liquid fuels, chemicals, electricity or steam) from a variety of feedstocks (Ondrey, 2006); it may be more efficient regarding thermodynamics, economics and the environmental aspects. Ragauskas et al. (2006) present a comprehensive discussion on the concepts and possibilities involving biorefineries, focused on the optimized options for biomass utilization for the sustainable production of energy, fuels and materials in both short and long term. With such goal, considerable governmental and private investments have been made in the last year (Genencor, 2003; Oils and Fats International, 2005; Ondrey, 2006), rising the expectation for commercial competitive plants in a short time horizon. Some analyses of hypothetical biorefineries have been presented, considering the employment of advanced technologies in their mature context. Lynd et al. (2005), based on ligno-cellulosic biomass, considered the future co-production of electricity, Fischer-Tropsch (FT) fuels and hydrogen, as well as scenarios for co-production of ethanolelectricity, ethanol-electricity-FT fuels, ethanolhydrogen, and other combinations of products and protein. In this analysis, some scenarios presented energy efficiencies greater than 70%, and economical competitiveness with conventional process based on oil prices of recent years.
