AB  - We conducted ex-situ catalytic fast co-pyrolysis (co-CFP) of corn stalk (CS) and 
      high-density polyethylene (HDPE) over HZSM-5 catalyst to enhance the production 
      of hydrocarbons. The effect of pyrolysis temperature and CS-to-HDPE mass ratio 
      (CS/HDPE) on the yield of condensable volatile organic products (CVOPs) and the 
      relative content of hydrocarbons were studied. The synergisms between CS and HDPE 
      were determined based on the difference between the experimental and theoretical 
      CVOP and hydrocarbons content. The results showed that the addition of HDPE 
      significantly promotes the production of CVOPs, reaching the maximum value at 750 
       degrees C. In the presence of HZSM-5, the CVOP and hydrocarbons production, especially 
      aromatics, were enhanced further, and 650  degrees C and 700  degrees C were the preferable 
      pyrolysis temperature for desired products. Benzene, toluene, and xylenes were 
      the predominant aromatics during the CFP process due to the good 
      shape-selectivity of HZSM-5, contributing to the highest selectivity of C5-C11 
      compounds in C5+ hydrocarbons. CS/HDPE mass ratio of 1:1 was a critical point for 
      enhancing aromatics yield. CS/HDPE < 1 was the recommended mass ratio for 
      increasing the relative aromatic hydrocarbons content, which increases as the 
      CS/HDPE mass ratio decreases. Meanwhile, we presented the potential reaction 
      pathways between CS and HDPE to explain the synergistic effects during the co-CFP 
      process.
