摘要：

Several Ru/Al2O3 glucose hydrogenation catalysts were tested in continuous operation. After use, spent catalysts were characterized by a variety of techniques to determine what changes had accompanied deactivation. The ruthenium tended to agglomerate, and changes in the physical properties of the Al2O3 support were observed. In addition, the buildup of iron, sulfur, and gluconic acid on the catalyst during use was detected. Experimental data strongly implicate these changes in causing catalyst deactivation. For example, when iron and gluconic acid poisoning is minimized, substantial improvements in catalyst stability are achieved.
