A patent application (Publication Number: US20240018435A1) discloses a method for increasing the hydrogen content in the product gas stream of torrefied solid recovered fuel pellets. The method involves torrefying the pellets to charred pellets while generating torrefaction gas, which is converted to torrefaction syngas containing hydrogen and carbon monoxide. The syngas is then processed in a CO shift unit to react carbon monoxide with water steam, generating shifted syngas rich in hydrogen. This shifted syngas is further processed in a low-temperature heat recovery unit, where it is in thermal exchange with water streams used for heating during the production of the product gas stream.

Furthermore, the patent application describes a plant for converting solid waste into a hydrogen-rich product gas stream. The plant includes a torrefaction unit, a torrefaction gas processing unit, a CO shift unit, and a low-temperature heat recovery unit with multiple heat exchangers. The plant also features a saturation column for adjusting the water content of the torrefaction syngas and various heat exchangers for heating water used in different processes within the plant. Overall, the plant and method outlined in the patent application aim to efficiently increase the hydrogen content in the product gas stream through a series of well-defined steps and heat exchange processes.
