route where its " biojet " fuel is produced
in parallel with kerosene production.
The biological component
of the fuel is made via a hydrogenated
esters and fatty acids (HEFA)
process, starting with vegetable-derived
materials.
FIGURE 3. This new multi-zone fluidized-bed
reactor can support production of petrochemical
feedstocks from crude oil
at play appears in the sustainable
aviation fuel sector. Earlier this year,
Spanish
fuel
manufacturer
Repsol
S.A. (Madrid; www.repsol.com) announced
the industrial-scale manufacture
of aviation fuel with biologically
derived content at its complex in
Tarragona, Spain. The company developed
a proprietary co-processing
The first batch of biojet fuel totaled
10,000 tons and had renewable
content of 5%, which complies
with the quality requirements established
in international specifications.
Repsol plans to extend the production
of biojet fuel to its other
sites, and to introduce a continuous
process (the two initial runs were
batch processes).
Refinery-petrochem integration
Over the past year, " Integrated refinery
and petrochemical sites significantly
outperformed their fuels-only
peers, " according to industry analyst
Wood Mackenzie (Edinburgh, U.K.;
www.woodmac.com). " This switch
in demand away from gasoline to
petrochemicals promotes the adoption
of refinery and petrochemical
integration, particularly for new facilities
in Asia and the Middle East.
An example of new technology
supporting the trend toward production
of chemical building blocks from
crude oil comes from a research
partnership between the King Abdullah
University of Science and Technology
(KAUST; Thuwal, Saudi Arabia;
www.kaust.edu.sa) and Saudi
Aramco (Dhahran, Saudi Arabia;
www.aramco.com). A research team
led by KAUST professor Jorge Gascon
has developed a new multi-zone
fluidized-bed reactor and a new catalyst
material that is capable of performing
several refinery upgrading
steps, resulting in the stable conversion
of crude oil to light olefins in a
single reactor with minimal byproduct
production.
The one-step C2C transformation
could prove to be a critical process
approach as demand for gasoline
and diesel decreases and demand
for petrochemicals rises. The technolFor
