AB  - Producing both hydrogen and high-value carbon nanotubes (CNTs) derived from waste 
      plastics is reported here using a pyrolysis-reforming technology comprising a 
      two-stage reaction system, in the presence of steam and a Ni-Mn-Al catalyst. The 
      waste plastics consisted of plastics from a motor oil container (MOC), commercial 
      waste high density polyethylene (HDPE) and regranulated HDPE waste containing 
      polyvinyl chloride (PVC). The results show that hydrogen can be produced from the 
      pyrolysis-reforming process, but also carbon nanotubes are formed on the 
      catalyst. However, the content of 0.3 wt.% polyvinyl chloride in the waste HDPE 
      (HDPE/PVC) has been shown to poison the catalyst and significantly reduce the 
      quantity and purity of CNTs. The presence of sulfur has shown less influence on 
      the production of CNTs in terms of quantity and CNT morphologies. Around 94.4 
      mmol H2 g(-1) plastic was obtained for the pyrolysis-reforming of HDPE waste in 
      the presence of the Ni-Mn-Al catalyst and steam at a reforming temperature of 800 
       degrees C. The addition of steam in the process results in an increase of hydrogen 
      production and reduction of carbon yield; in addition, the defects of CNTs, for 
      example, edge dislocations were found to be increased with the introduction of 
      steam (from Raman analysis).
