Catalytic static mixers, 3D printed from nickel alloys, were treated with etching or leaching solutions to activate their surfaces for use in hydrogenation of alkenes, aldehydes and nitro-groups. Their performance was benchmarked against industrial standard alumina catalysts, using a tubular continuous flow reactor. These novel structured catalysts were additively manufactured from printer-grade Monel and Inconel powders. Especially the Monel-type catalysts, consisting predominantly of nickel and copper by weight, presented a surface layer significantly enriched in nickel after the leaching protocol, which resulted in a high catalytic activity and a surprising selectivity towards unsubstituted double bonds.

通过腐蚀性化学处理制成的 3D 打印镍催化静态混合器,用于连续流加氢

由镍合金 3D 打印的催化静态混合器用蚀刻或浸出溶液处理以活化其表面,用于烯烃、醛和硝基的氢化。它们的性能与工业标准氧化铝催化剂相比,使用管状连续流动反应器进行了基准测试。这些新型结构化催化剂由打印机级蒙乃尔合金和因科镍合金粉末增材制造。特别是蒙乃尔型催化剂,按重量计主要由镍和铜组成,在浸出方案后呈现出显着富含镍的表面层,这导致了高催化活性和对未取代双键的惊人选择性。
