Abstract For previously studied Fischer–Tropsch nanosized Fe catalyst slurries, polymer compounds with or without polyconjugating structures are used as precursors to form the catalyst nanomatrix in situ, and several catalytic experiments and X-ray diffraction and atomic force microscopy measurements are performed. The important and different roles of the paraffin molecules in the slurry medium in the formation and function of composite catalysts with the two types of aforementioned polymer matrices are revealed. In the case of the polyconjugated polymers, the alkanes in the medium are “weakly” coordinated with the metal-polymer composites, which does not affect the effectiveness of the polyconjugated polymers. Otherwise, alkane molecules form a “tight” surface layer around the composite particles, which create transport complications for the reagents and products of Fischer-Tropsch synthesis and, in some cases, can change the course of the in situ catalyst formation.

基于聚共轭体系的超细金属聚合物催化剂用于费托合成

摘要 对于先前研究的 Fischer-Tropsch 纳米 Fe 催化剂浆料，具有或不具有多共轭结构的聚合物化合物被用作原位形成催化剂纳米基质的前体，并进行了一些催化实验和 X 射线衍射和原子力显微镜测量。揭示了浆液介质中的石蜡分子在与上述两种聚合物基体形成复合催化剂的形成和功能中的重要和不同的作用。在聚共轭聚合物的情况下，介质中的烷烃与金属-聚合物复合材料“弱”配位，这不会影响聚共轭聚合物的有效性。否则，烷烃分子会在复合颗粒周围形成“紧密”的表面层，
