表面分散剂对Ru/AC氨合成催化剂的影响

Influence of Surface Dispersant on Ru/AC Catalyst for Ammonia Synthesis

采用表面分散剂处理Ru/AC氨合成催化剂的钌盐浸渍液,研究了表面分散剂对钌催化剂活性、分散度及耐热性的影响,结果表明合适的表面分散剂能有效提高钌催化剂的Ru金属分散度从而提高催化性能。

The Ru /AC catalysts for ammonia synthesis were prepared by the surface dispersant in the impregnation solution which contains ruthenium salt.The influence of dispersant on activity,dispersion and heat resistance of ruthenium catalyst was studied and concluded that some appropriate surface dispersants will improve the capability of ruthenium catalyst effectively.
