Abstract
In order to solve the problems of microwave plasma decomposition of 13CF4,such as com-plex operation process,harsh decomposition conditions and easy corrosion of reaction tubes,the ther-mal catalytic decomposition of 13CF4 to produce 13CO2 was studied.Under the condition of anhydrous and high temperature,13CF4 was decomposed into 13CO2 by gas-solid reaction between 13CF4 and solid defluorination agent,using γ-Al2O3 as solid defluorination agent,meanwhile,the metal oxide in the defluorination agent is converted into metal fluoride.The results show that when the flow rate of re-action gas is 120 mL/min,the loading amount of catalyst is more than 60 g,the content of O2 in feed gas mixture is more than 50%,and the temperature of high temperature tubular furnace is 900 ℃,the conversion of γ-Al2O3 catalyst to 13CF4 gas is over 90%,which has good catalytic decomposition per-formance and can realize continuous catalysis and decomposition.The catalytic decomposition process has the advantages of simple process,convenient operation and very high carbon yield,and can be used in industrial production.关键词
