中文摘要 | 本文主要係探討以金屬鎳為主的數種雙金屬觸媒,在常壓下進行氣相甲醇羰基化 反應。由實驗結果顯示,鉛鎳╱活性碳觸媒比其它雙金屬和鎳╱活性碳觸媒具有較佳的活性 ,並可使甲醇和一氧化碳反應得到較高的醋酸甲酯和醋酸選擇率。以鉛鎳╱活性碳觸媒和鎳 ╱活性碳觸媒反應所得產物分佈並沒有明顯的差異。活性碳是唯一可使觸媒有活性的載體。 一氧化碳在這些觸媒上的化學吸附量以鉛鎳╱活性碳觸媒為最高,但是氫氣在鉛鎳╱活性碳 觸媒的化學吸附量並沒有比鎳╱活性碳觸媒顯著增加。以鉛鎳╱活性碳觸媒進行反應時,其 反應時間對甲醇轉化率及產物分佈的影響,本實驗也有探討。 |
英文摘要 | Vapor phase carbonylation of methanol was investigated under atmospheric pressure on various nickel-based bimetallic catalysts. Pb-Ni/C was found as having a higher activity than the other four bimetallic catalysts and unleaded Ni/C in converting methanol and CO to methyl acetate and acetic acid. Product distributions between Ni/C and Pb-Ni/C did not markedly differ from each other. Catalyst with activated carbon support is the only one shown activity. Characterizing these catalysts by chemisorption of CO and H ��, the amount of adsorption of CO became substantially enhanced by the addition of Pb to Ni/C, while the amount of adsorption of H �� made no difference between Ni/C and Pb-Ni/C. The effect of time on stream on methanol conversion, as well as products distribution are also investigated in this research. |
