Nickel membranes for in-situ hydrogen separation in high-temperature fluidized bed gasification processes

In the experimental section several commercial nickel capillaries were tested for their hydrogen permeability and the results from a parameter study regarding the influence of synthesis gas components like CO, CH4 and H2O on permeation are shown. The nickel membranes were also tested in hydrogen containing H2S, which can be present in synthesis gas in concentrations of up to 1000 ppm.
