法国石油研究院开发的Ｐｏｌｙｎａｐｈｔｈａ和Ｓｅｌｅｃｔｏｐｏｌ拟烷基化工艺可以将轻质含烯烃馏分转化为汽油和煤油,且转化率高。这一费用低的工艺使得炼厂对原料和产品分布具有广泛的选择性。工艺的原料是丙烯和混合丁烯或碳三碳四馏分,如来自裂化工艺的碳三碳四馏分。 The Polynaphtha and Selectopol pseudometharification processes developed by the French Petroleum Institute convert light olefin-containing fractions into gasoline and kerosene at high conversion rates. This low-cost process allows the refinery to have a wide range of feedstock and product distribution options. Raw materials for the process are propylene and mixed butenes or carbon three carbon four fractions, such as carbon three carbon four fractions from the cracking process.
