❓ ATR: how does it work? ⤵️ Autothermal Reforming (ATR) is emerging as a promising technology to produce low-carbon hydrogen on a large scale. It is based on an advanced chemical process. Unlike traditional processes, which require large amounts of external heat, ATR combines two chemical reactions: partial oxidation and steam reforming. These two reactions occur simultaneously within a reactor, generating the heat needed for the process through an autothermal reaction. This means that the syste
