Parametric study on the steam reforming of phenol-PET solution to hydrogen production over Ni promoted on Al2O3-La2O3catalyst

Production of hydrogen from plastic waste could be a prospective key to the ecological problems resulted from waste. To further explore the process, a 32-runs parametric study on the steam reforming of Polyethylene terephthalate (PET) dissolved in phenol was conducted in a fixed bed reactor using Ni...

TP Chemical technology Production of hydrogen from plastic waste could be a prospective key to the ecological problems resulted from waste.
