AB  - Three plastics, high density polyethylene (HDPE), polypropylene (PP) and 
      polystyrene (PS), were individually co-pyrolysed with deoiled cake of jatropha 
      (JC) at 400 and 450 degrees C in a batch reactor in the presence of nitrogen under 
      atmospheric pressure to produce modified liquid fractions. At higher temperature 
      (450 degrees C), the yield of liquid fractions by the pyrolysis of plastics (HDPE, PP and 
      PS) alone was found to increase by 11, 12.5 and 11% for HDPE, PP and PS, 
      respectively. Furthermore, the gaseous fraction increased by 1.3 to 2.6% while 
      the residue generation reduced by 12.3 to 15.1%. In comparison with only plastics 
      pyrolysis, the yield of the liquid fraction improved by 2.0 to 4.9% for their 
      co-pyrolysis with JC. Gas chromatography-mass spectrometry analyses demonstrated 
      that the co-processing afforded a reduction of paraffin and olefins in the liquid 
      fractions for all of the experiments. This reduction was found to be in the order 
      of PS > PP > HDPE. Furthermore, the proportion of oxygenates in the liquid 
      product increased in the order of PP > HDPE > PS. Physical characteristics such 
      as oxygenates, water contents, acid values and viscosity increased during the 
      co-pyrolysis of plastics and JC in contrast to the liquid fractions obtained from 
      the pyrolysis of pure plastics. Furthermore, co-pyrolysis offered a reduction in 
      calorific values.
