RECYCLE CONTENT AMMONIA

A process for making recycle content ammonia by reacting hydrogen with nitrogen. At least a portion of the hydrogen is obtained directly or indirectly by molecular reforming a mixed plastic waste or pyrolysis product feedstock. The molecular reforming can be a steam reforming process or a partial oxidation process, such as a partial oxidation gasifier, to generate the syngas used as a source of hydrogen. The recycle content associated with the ammonia can be obtained from the mixed plastic waste, the recycle content in the pyrolysis product, such as pyoil or pygas, or the recycle content in the syngas or the purified hydrogen stream from the syngas.
