摘要
Abstract
This study is based on gas diffusion method,using methane as processing gas to explore the production technology route of high abundance carbon-13 isotopes.Single stage and four stage cascade diffusion separation experiments were conducted,and preliminary cascade calculations were carried out.Under the existing experimental conditions,the maximum total separation coefficient of methane in single-stage experiments reached 1.025,and in four stage cascade experiments,the maximum total separation coefficient reached 1.018.Based on the experimental results,cascade calculation and optimization were carried out,and the product with a carbon-13 abundance of over 90%can be obtained at the heavy fraction end through a three-step cascade of about 600 stages.This study verified the feasibility of using methane gas as processing gas for diffusion separation of carbon isotopes,and provided a technical basis for carbon isotope diffusion separation.关键词
