US 2026/0097378 A1 · PROCESSES AND METHODS FOR PRODUCING HYDROGEN AND CARBON FROM HYDROCARBONS

Abstract

A system includes a pyrolysis reactor containing a bed of particulates, a solids heating section, and a separator in fluid communication with the pyrolysis reactor through the product gas outlet. The pyrolysis reactor comprises a feed gas inlet at a lower portion of the bed, a product gas outlet above the bed, a particulate outlet above the feed gas inlet, a particulate inlet near the top of the bed, and a solids product outlet in a lower portion of the pyrolysis reactor. The solids heating section is configured to accept a portion of the particulates from the pyrolysis reactor through the particulate outlet, heat the portion of the particulates to form heated particulates, and return the heated particulates to the pyrolysis reactor through the particulate inlet, and the separator is configured to separate any particulates in a product gas produced, and return the particulates to the pyrolysis reactor.
