重整非芳催化裂解生产低碳烯烃研究

摘要

分析了重整非芳的组成,并利用微型固定床反应实验装置研究了重整非芳在平衡催化剂上生产低碳烯烃的裂解性能.结果表明:重整非芳中主要含有正构烷烃和异构烷烃及少量的环烷烃;反应温度对重整非芳转化率、总低碳烯烃产率和汽油性质的影响较大,随着反应温度的提高,重整非芳的转化率和干气以及焦炭产率呈上升趋势,液体产物产率和总低碳烯烃选择性呈下降趋势,汽油中异构烷烃含量降低,芳烃含量增加,烯烃略有减少.%The composition of reforming non-aromatic was analyzed, and the catalytic pyrolysis was investigated in a Miniature fixed bed reaction experiment device with equilibrium catalyst to produce light olefins. The experimental results show that reforming non-aromatic is mainly composed of normal paraffin and isomeric alkane and a small amount of naphthene. Reaction temperature had a greater influence on the conversion of reforming Non-aromatic and the yield of total light olefins and the gasoline properties. With the increase of reaction temperature, the conversion and the yield of dry gas and coke is on the rise, the liquid product yield and light olefins selectivity is on the decline, isomerization alkane content in gasoline is reduced, aromatic content is increased, the olefin reduced slightly.
