新型蒽醌加氢催化剂的制备及加氢性能研究

在蒽醌法生产过氧化氢中，采用蝶形氧化铝载体，通过控制贵金属浸渍条件，制备出蛋壳分布的新型钯催化剂。催化剂贵金属负载量低，活性组分浸渍层薄，催化剂活性高及反应稳定性好。实验室和工业模式评价实验表明，制备的催化剂表现出良好的活性及稳定性，其时空产率为工业用催化剂的1.5倍以上。

Investigation of anthraquinone hydrogenation over a new catalyst

A novel anthraquinone hydrogenation catalyst for hydrogen peroxide production was prepared with papilionaceous alumina carrier by impregnation method. The catalyst had low Pd loading and thin active layer. High catalytic activity and stability were obtained in the anthraquinone hydrogenation process in the lab test and pilot experiments. The space time yield over the catalyst was as 1.5 times as that over commercial catalysts.
