Processing solid recovered fuel pellets into hydrogen-rich product gas
A recently granted patent (Publication Number: US11952277B2) discloses a method for processing solid recovered fuel pellets. The method involves torrefaction of the pellets at a specific temperature range, milling the charred pellets, removing metal residues, gasifying the pellets to raw syngas, performing CO shift reactions, and generating a product gas stream rich in hydrogen through purification steps.
Additionally, the patent claims include details such as the thermal cracking of torrefaction gas for torrefaction syngas generation, milling charred pellets to specific particle sizes, removal of metal residues using eddy current technology, and the separation of hydrogen from syngas using pressure swing adsorption. The method also involves utilizing purge gas from the separation process for the CO shift reaction and as fuel gas, showcasing a comprehensive approach to processing solid recovered fuel pellets efficiently.
