Abstract
A pulsed flow process for the reduction of UF.sub.6 where the process may be continuous or batch starting without a seed bed. The initial amplitude and frequency of the pulsed flow is altered as a bed of particle-form material is formed and thereafter the particle-form product of the reaction is removed from the reaction zone.
Claims1
A process for the treatment of uranium hexafluoride which comprises the steps of passing a flow of gaseous uranium hexafluoride to a reaction zone, passing a pulsed flow of a gaseous reactant medium comprising an organic halide into the reaction zone to maintain a zone temperature on the order of 600.degree. F and a pressure slightly above atmosphere to enable the uranium hexafluoride to initially form only from said gases fine solid particles containing substantially only UF.sub.4, continuing the treatment of the uranium hexafluoride within said reaction zone to increase the size of the formed fine particles and to accumulate further fine particles in the reaction zone, and adjusting the rate of pulsed flow of reactant medium to the reaction zone by increasing the pressure of the reactant medium to a maximum pressure about twice atmospheric while simultaneously reducing the frequency of the pulsed flow in accordance with the amount of solid particles therein.
