iso-paraffin

The effect of integral mode on the quantitative results of n-, and iso-paraffins and carbon number distributions of paraffin waxes determined by GC is discussed.

本文考察了积分方式对气相色谱法测定石蜡中正异构烃及相应的碳数分布定量结果的影响,并与分子筛吸附法测定石蜡正异构烃结果对比,验证了其准确性。

The mechanism of iso-alkanes synthesis by the hydrogenation of carbon dioxide over Fe-Zn-Zr/HY composite catalyst at 340℃,5.

实验结果表明:(1)催化剂的作用主要来源于Fe-Zn-Zr和HY分子筛两种催化剂的独立作用;(2)甲醇是整个反应的中间产物;(3)CO不是异构烃合成的必须中间产物,CO与CO2加氢合成烃类的途径截然不同;(4)Fe-Zn-Zr和HY都与异构烃的形成有着直接的关系。
