F-T合成产物分布的数理统计处理

PROBABILISTIC TREATMENT OF PRODUCT DISTRIBUTION OF THE FISCHER-TROPSCH SYNTHESIS

F-T合成是一结构敏感的表面聚合反应,其产物分布比较复杂,许多模型只能近似地描述F-T合成反应的产物分布规律。本文系统总结了近几年用数理统计法对F-T合成产物分布的处理结果,这些方法的共同假设是F-T合成的三类主要产物——烷烃、烯烃和含氧有机物——是经由同一中间体形成的,只是链终止的方式不同。详细介绍了T-W模型和Basini模型,以及对ASF分布的深入分析。

The Fischer-Tropsch synthesis can be considered as a structure-sensitive non-trival surface polymerization. Its product distribution may be described by several models approximately. The focus of the review is on probabilistic treatment of the Fischer-Tropsch synthesis. This is done by assuming that common intermediates originate three classes of products-alkanes(paraffines), olefines, alcohols through different types of chain termination. The T-W(Taylor-Wojciechowski) model and the Basini model are introduced in detail, and the ASF distribution has been further discussed.
