摘    要:在轻烃芳构化催化剂上进行异丁烷和富含异丁烷的碳四芳构化产品液化气的芳构化反应研究,考察了反应温度、反应压力及进料空速对异丁烷转化率的影响。结果表明,富含异丁烷的碳四芳构化产品液化气在反应温度为400 ℃、进料质量空速为0.5 h-1、反应压力为1.0 MPa的条件下,经过催化反应可以得到60.05%的丙烷和11.57%的汽油馏分,分别可用作乙烯裂解原料和高辛烷值汽油调合组分,(干气产率+损失)小于3%。

关 键 词:异丁烷  芳构化  催化剂  液化气

Abstract:The aromatization of i-butane over light hydrocarbon aromatization catalyst was investigated using pure i-butane and LPG rich in i-butane from C4 aromatization unit as feed respectively. The effect of reaction temperature, reaction pressure and space velocity on the conversion of i-butane was studied. Results showed that with LPG rich in i-butane as feed, under the conditions of a WHSV of 0.5 h-1, a reaction temperature of 400℃and a reaction pressure of 1.0 MPa, the yield of propane, gasoline fraction and dry gas plus loss was 60.05%, 11.57% and less than 3%, respectively. The propane can be used as feed of ethylene cracking, and the produced gasoline fraction is a high octane gasoline blending component.
