- 中文摘要: 在一氧化碳或重組氣中,混入各種毒素,進行一氧化碳低溫轉化觸媒之中毒試驗,以研討影響觸媒中毒之各種因素及其中毒作用。 硫化氫、二氧化硫、乙炔等均可使觸媒中毒而減少其活性。在毒素濃度較高時,其中毒作用係依硫化氫、二氧化硫、乙炔順序而增大。此種觸媒之活性,隨反應溫度之減低、毒素濃度之增加或氧化銅含量之減少,均有減低之趨勢。以純一氧化碳為原料時,硫化氫對觸媒之中毒作用為不可逆性。自製觸媒LC-92對硫化氫之耐毒性在175C~300C之間與工業觸媒G-66B近似。
- 英文摘要: The poisoning of catalysts by various poisons in the lowtemperature CO conversion was studied. Experimental results showed that , and all tended to poison the catalyst and decrease its activity. In high concentration of poisons,the poisoning effect increased in the order of , , . The activity of catalysts tended to decrease with increasing concentration of poisons ingases and decreasing reaction temperature or CuO content. With pure CO as rawmaterial, the catalyst was irreversibly poisoned by . The resis-tivity against poisoning of the self-made LC-92 catalyst between 175C-300Capproximated to that of G-66 Bcatalyst.
