CA_3139620_A1

Resumen de: US2023034215A1

A process for the production of direct reduced iron (DRI), with or without carbon, using hydrogen, where the hydrogen is produced utilizing water generated internally from the process. The process is characterized by containing either one or two gas loops, one for affecting the reduction of the oxide and another for affecting the carburization of the DRI. The primary loop responsible for reduction recirculates used gas from the shaft furnace in a loop including a dry dedusting step, an oxygen removal step to generate the hydrogen, and a connection to the shaft furnace for reduction. In the absence of a second loop, this loop, in conjunction with natural gas addition, can be used to deposit carbon. A secondary carburizing loop installed downstream of the shaft furnace can more finely control carbon addition. This loop includes a reactor vessel, a dedusting step, and a gas separation unit.

NºPublicación: AU2021297198A1 02/02/2023

Solicitante:

ROYAL MELBOURNE INSTITUTE OF TECH LIMITED

WO_2021258157_A1

Resumen de: AU2021297198A1

The invention relates to a proton flow reactor for use in storing and releasing energy. In use, a slurry of storage particles in a liquid electrolyte may pass through a first half cell of the proton flow reactor. When the proton flow reactor is in charge mode, protons are bonded or otherwise attracted to the storage particles to form charged storage particles charged with hydrogen, which can then be stored and/or transported for later use. When the proton flow reactor is in discharge mode, protons are removed from the charged storage particles to fuel an electrochemical reaction, thereby generating electricity. Alternatively, the proton flow reactor in discharge mode can be configured to generate hydrogen gas directly from the in-flowing charged carbon particles.
