Hydrogen production from the catalytic pyrolysis-gasification of polypropylene using a two-stagereaction system has been investigated. In this paper, three important process conditions: water flow rate,carrier gas flow rate, and gasification temperature were investigated in relation to hydrogen production. Itis suggested that the water flow rate and gasification temperature have a significant influence on hydrogenproduction from pyrolysis-gasification of polypropylene, whereas the carrier gas flow rate shows littleinfluence. With increasing water flow rate, the gas yield related to the mass of polypropylene increasedfrom 123.6 to 213.9 wt%when the water flow rate was increased from 1.90 to 9.49 g h-1, then decreased to 195.5 wt%at the water flow rate of 14.20 g h-1. The hydrogen concentration and the potential hydrogen production also showed the highest yields at the water flow rate of 9.49 g h-1. With increasing gasification temperature, the pyrolysis-gasification of polypropylene seems to be promoted to generate higher yields of gas and hydrogen.
