Abstract: A process for on-site hydrogen reforming is disclosed. The process includes providing a combined reformer heat exchanger component in which heated air, steam, and hydrocarbon fuel react to form process gas containing hydrogen, and the process gas is cooled via the heat exchanger. The combined components enable reductions in size, materials, costs, and heat loss. Additionally, as the heat exchanger side of the component operates at a cooler temperature, an uninsulated flange for access to the catalyst chamber can be used. A combined combustion heat exchanger component is also provided with similar advantages. Process gas is processed, and hydrogen gas is produced via a purification process.

Abstract: A process and arrangement for contacting a moving bed of compact particulate material, usually catalyst, with a radial flow of fluid maintains an unconfined surface of catalyst particles in place by passing fluid axially into the upper surface of the bed and maintaining radial gas flow across an inlet screen at an elevation that is above the upper most elevation of perforations for withdrawing gas flow from the particulate bed. Two vertical screens confine the bed of catalyst. Perforations cover substantially the entire length of the inlet screen. The outlet portion of the screen has perforations that end below the top of the free surface of the catalyst bed and define an upper bed portion therebetween. The inlet screen directs gas flow radially across the inlet screen into an upper portion of the bed and cause at least partial axial flow of gas through the upper portion of the particle bed.
