Abstract
Thermodynamic calculation of isobutane dehydrogenation reaction have been finished in detail by EXCEL program. The relationships of reaction temperature in isobutane dehydrogenation with enthalpy, Gibbs free energy and chemical equilibrium constants have been obtained and the option conditions have been given. The influences of the side effects of the main reaction are estimated. The influence of temperature, total pressure, ratios of hydrogen to alkane and inert gas to hydrogen on isobutane equilibrium conversion have been discussed and the appropriate reaction conditions and process parameters have been obtained. The results indicate that all the reactions apart of R5 are endothermic. The isobutane dehydrogenation reaction can spontaneously carry out when temperature is more than 850K.The equilibrium conversion increases with temperature rising and total pressure dropping. The isobutane conversion increases with decrease of ratio for H2/C4 and rise of ratios for N2/ H2.
