Importance of Biofuels
Mid

Blending

Historic Development
Cracking
of
petroleum
hydrocarbons
was
originally
done
by
thermal
cracking
Due
to
the
production
of
more
gasoline
with
a
higher
octane
rating
thermal
cracking
was
replaced
by
catalytic
cracking
Most
important
conversion
process
used
in
petroleum
refineries
Conversion
of
high
boiling
hydrocarbon
fractions
of
petroleum
crude
oils
to
more
valuable
gasoline
,
olefinic
gases
and
other
products

for
