在常规反应器和膜反应器中研究了以爆轰纳米金刚石（DND）为载体的Pt-Ni和Pt-Ru纳米催化剂在乙醇水蒸气重整制氢（ESR）过程中的催化性能。在Pt-Ru/DND催化剂的情况下，在总金属含量为0.3%和原子Pt/Ru比为9/1时，获得最高的氢气产率和纯度。它表明，实现ESR过程中的膜反应器中的同时通过钯钌膜去除氢产生高纯度的氢气，没有任何其他气体产物。
Production of hydrogen in the course of ethanol steam reforming (ESR) on bimetallic Pt-Ni and Pt-Ru nanocatalysts supported on detonation nanodiamonds (DND) was studied in conventional and membrane reactors. The highest hydrogen yield and purity were achieved in the case of Pt-Ru/DND catalysts at total metal content of 0.3% and atomic Pt/Ru ratio of 9/1. It is shown that realization of ESR process in the membrane reactor with simultaneous hydrogen removal through the Pd-Ru membrane produces hydrogen of high purity, free of any other gaseous products.
