Preparation of Highly Enriched Carbonminus;13 by Thermal Diffusion of Methane

摘要

Methane, enriched to 93 in13C, was prepared by thermal diffusion in an 11hyphen;column, ninehyphen;stage isotope separation cascade. The experimental thermalhyphen;diffusion cascade was successfully operated at essentially steadyhyphen;state conditions after a transient period of 292 days. Behavior of the cascade during steady operation was found to be in good agreement with the predictions of binary cascade theory.
