毛细管气相色谱测定改进费-托法合成汽油辛烷值的研究

Octane Number Determination for MFT Gasoline by Capillary Gas Chromatography

采用高分辨毛细管气相色谱法对改进费－ 托（ ＭＦＴ） 法合成汽油馏分进行了组成分析， 按其化学类型和各组分的辛烷值特性分组， 并与标准方法测定的辛烷值进行关联和线性回归分析， 获得了每组的有效辛烷值及计算ＭＦＴ合成汽油辛烷值的研究法辛烷值（ＲＯＮ） 和马达法辛烷值（ ＭＯＮ） 方程。该法的建立， 对正在研究开发中的ＭＦＴ合成汽油的工艺、动力学研究、催化剂评价等具有现实意义。

The chemical composition of modified Fischer _ Tropsch gasoline is determined by temperature _ programmed capillary gas chromatography. The constituents are divided into groups according to their chemical characteristics and octane numbers. These data are then correlated and regressed with the octane numbers measured by a standard method. On the basis of regression analysis, coefficients or effective octane numbers of all groups can be calculated. Formulae for the calculation of research octane number(RON) and motor octane number(MON) are provided in this paper. This work is of great interest for the development of MFT process, kinetic study and catalyst characterization.
