摘　　要：裂解C5馏分选择性加氢饱和二烯烃后,醚化产物作为高辛烷值汽油调合组分是一条投资少、见效快的工艺路线。本文主要考察和研究了反应压力、空速、反应温度、醇烯摩尔比对叔戊烯转化率的影响。脱除甲醇后,裂解C5馏分选择性加氢后的醚化产物的研究法辛烷值为95左右,烯烃含量小于35%(ω),硫含量小于10×10-6(w),芳烃含量小于1%(w),是一种优质、清洁的高辛烷值汽油组分。与FCC汽油组分调合,可以提高汽油辛烷值,增加汽油氧含量,改善汽油的性能。It is a process with low investment and great profit to use the C_5 etherealization product as the blending component of gasoline with high octane number.The C_5 fraction is cut from steam cracking and it's diolefins are saturated by selective hydrogenation. This paper mainly studies the effect of pressure, LHSV, temperature and mole ratio of alcohol and alkene on conversion ratio of tertiary amylene. After methanol is taken out, the research octane number of C_5 etherealization product is about 95. The alkene content is less than 35%, the sulfur content is less than 10μg/g and the aromatics content is less than 1%, it is a clean and high quality gasoline component with high octane number. It will improve gasoline quality and increase the octane number and the oxygen content after it is blended with FCC gasoline.
