A recently granted patent (Publication Number: US11964868B2) outlines a novel process for conducting an endothermic steam reforming of hydrocarbons to produce synthesis gas. The process involves utilizing a fluidized bed reactor with specific characteristics, including the presence of electrically conductive particles and a catalytic composition. The method includes steps such as heating the fluidized bed to a specific temperature range, conducting the steam reforming reaction in the presence of steam, and utilizing specific types of electrically conductive particles in the bed. Additionally, the process involves pre-heating the reactor and passing an electric current through the fluidized bed to achieve the desired reaction temperature.

Furthermore, the patent also describes an installation for performing the endothermic steam reforming process, which includes a fluidized bed reactor with specific components such as electrodes, a reactor vessel, and fluid nozzles for introducing gases. The installation is characterized by the presence of electrically conductive particles and a catalytic composition in the bed, with specific resistivity and composition requirements. The installation can consist of multiple fluidized bed reactors connected in various configurations, each serving different functions such as heating and reaction zones. Overall, the patented process and installation offer a unique approach to steam reforming of hydrocarbons, potentially leading to more efficient synthesis gas production.
