氧对丙烷脱氢反应体系影响的热力学分析
Thermodynamic analysis of effects of oxygen addition on dehydrogenation of propane
摘要
Abstract
The thermodynamics of both oxidative dehydrogenation and dehydrogenation-oxidation of propane were analyzed and compared with that of simple dehydrogenation of propane. Twenty seven products from the reactions of cracking,partial oxidation and deep oxidation of propane were taken into consideration. The molar fractions of the feed and the products in the Gibbs reactor under isotonic and isothermal conditions were calculated by using Aspen Plus simulation software. The effects of oxygen addition on the molar fraction of target product propylene and the composition of other products under pressure of 0.1MPa and in the temperature range of 300—700℃ were discussed. For whichever propane dehydrogenation system,i.e. adding oxygen before or after the dehydrogenation, addition of oxygen was extremely harmful to production of propylene. The higher the temperature and the larger the oxygen addition amount,the less the propylene production and the greater the feed loss. The major byproducts were CH4 and CO rather than CO2 and H2O.关键词
