A sequential process for hydrogen production based on continuous HDPE fast pyrolysis and in-line steam reforming

A continuous process has been developed consisting in the flash pyrolysis (500 ºC) of high density polyethylene (HDPE) in a conical spouted bed reactor (CSBR) followed by steam reforming in a fluidized bed reactor (Ni commercial catalyst). The effect reforming temperature in the 600-700 ºC range, sp...
