    abstract = {Cypress pruning residues have the potential to
be converted to bio-oils using a pyrolysis process. In this
research, cypress-pruning residues including ground
particles of stems and leaves were separately pyrolysed to
produce pyrolysis oil. A fixed-platform reactor equipped
with a condenser was used for deriving pyrolysis oil from
cypress pruning residues. The effect of pyrolysis and
condensing temperatures on the yield of bio-oils were
investigated and optimized using the RSM. The
investigated reactor temperature ranged from 350-60°C
and the condensing temperature ranged from-5-20°C.
The results indicated that the thermal values of the bio-oil
obtained from stem and leaf samples were 22.32 and
24.02 MJ kg<sup>&#150;1</sup>, respectively which showed an increase of
about 30% compared to the thermal values of their
corresponding raw materials. The optimum operating
reactor temperature was 523&#176;C for the stem particles and
494&#176;C for the leaves particles. The optimum condensing
temperature for both leaves and stem particles was -12&#176;C.
At the optimum conditions, the yield of pyrolysis oil was
(33% w/w) for the stem particles and (14% w/w) for the
leaves particles.}
