【摘要】 为研究和考察异丁烷在本体催化剂Cr2O3上的脱氢反应性能和效果,在自行设计的微型床反应器装置上进行了脱氢反应性能试验,结果表明,在常压下,反应温度600℃,原料流速20mL·min-1时,该催化剂表现出良好的催化性能。用XRD等手段对催化剂的结构进行了研究,结果表明碱源与催化剂的晶相特征有关,K:Cr=2催化剂有最高的产率和稳定性。更多还原

【Abstract】 The experiment was proceed at microreactor device to validate dehydrogenation and effect of Cr2O3 catalyst acted by isobu-tane.We could draw a conclusion from the experiment result that isobu-tane had a better catalysis capacity at normal pressure force,600℃ and raw material current velocity 20 mL·min-1.Catalyst structure was researched by XRD means,the result indicated that alkali source was related with crystalline phases character of catalyst,K-Cr-2 catalyst had maximal productive rate and stability.更多还原
