Simulation of Hydrogen-Deuterium Exchange Behavior in the Sphere Pd-Filled Column[J]. Chinese Journal of Inorganic Chemistry, ;2013, 29(8): 1626-1632. doi: 10.3969/j.issn.1001-4861.2013.00.301

A hydrogen-deuterium exchange reaction model was constructed by combining the Sphere Particle Exchange Model (SPEM) and the Gas-Solid Surface Exchange Model, and programmed in terms of numerical algorithm using FORTRAN language to simulate the H-D exchange reaction in a column filled with palladium (Pd) particles. This model was then used to study the influence of the properties of Pd material, including its size and density in the column, the length of the column, the velocity of the gas flow and temperature, etc., on the exchange reaction. The calculation show that low flow velocity, high density and small size of Pd particles, longer column and higher temperature may accelerate the exchange reaction of D by H, while the diameter of column has no effect when the diffusion model used here holds.
