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–1, 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°C for the stem particles and 494°C for the leaves particles. The optimum condensing temperature for both leaves and stem particles was -12°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.
