Abstract
Fast pyrolysis technology is currently moving forward to
commercialization, and demonstration plants are at the
commissioning stage. The quality of bio-oil differs
significantly from fossil fuels, and therefore, upgrading
technologies are needed to improve the fuel properties of
bio-oil. Co-processing of bio-oil in refinery fluid
catalytic cracking (FCC) would have many economic
advantages compared to other upgrading technologies
because no essential modifications to the refinery are
needed. However, because of its different chemical
composition, the introduction of bio-oil into the FCC
unit will introduce uncertainty to the refinery
operation. In this paper, co-processing of dry thermal
bio-oil, catalytic pyrolysis oil, and hydrotreated
bio-oil was compared using a micro activity test (MAT)
setup. The experiments show that the bio-oil
concentration during co-processing should remain low to
avoid high coke formation. Co-processing of dry bio-oil
also resulted in a much lower liquid yield compared to
catalytic pyrolysis oil and hydrotreated bio-oil. This
was probably caused by the higher amount of sugar-like
material in the dry bio-oil. The differences between
catalytic pyrolysis oil and hydrotreated bio-oil were
relatively small, except for the coke formation tendency,
which was higher for the more aromatic catalytic
pyrolysis oil.
