研究了通过多元醇还原生产碳负载型铂催化剂的连续方法。将反应物分散体快速加热至反应温度，同时流过直接电加热的管，随后流过下游等温管式反应器。计算了与所需短加热时间对应的适当内径。内径的某个下限是由绕过稳态操作的颗粒团聚体的暂时性堵塞引起的。从加热时间和堵塞方面评价了管径。证明了利用管式反应器连续制备具有低粒度和均匀分布的颗粒的碳纳米管负载的铂催化剂是可能的。
A continuous process to produce carbon‐supported platinum catalysts by polyol reduction was examined. The reactant dispersion was rapidly heated up to reaction temperature while flowing through a directly electrically heated tube followed by a downstream isothermic tubular reactor. Appropriate inner diameters corresponding to the desired short heating‐up times were calculated. A certain lower limit for the inner diameter is caused by temporary pluggings of particle agglomerates circumventing steady‐state operation. Tube diameters were evaluated with respect to heating‐up times and plugging. It was proved that with a tubular reactor a continuous preparation of carbon nanotube‐supported platinum catalysts with a low particle size and evenly distributed particles is possible.
