Abstract
The
refining industry faces increasingly stringent policies on renewable content in
its products. A possible response is to produce diesel and gasoline from the
gasification of biomass via a Fischer–Tropsch (FT) synthesis. Authors compare
heat integrating a biomass–to–FT syncrude process with a refinery vs. a
stand–alone biomass–to–FT syncrude process, in terms of the consequences for
GHG emissions and energy balances.
The upgrading of the FT syncrude in both cases is accomplished at
the refinery, in the existing units or in new units. The studied system
includes a circulating fluidized–bed biomass gasifier with a biomass input of
500 MW and a complex refinery with a crude oil capacity of 11.4 Mt/y. The
integrated FT syncrude production shows the greatest potential for reductions
in GHG emissions. Even so, the GHG emission mitigation potential of using
biomass for FT fuel production is smaller than co–firing biomass with coal in
coal power plants.
