The partial oxidation of ethane to ethylene and acetic acid on supported MoVNbPd/TiO₂ (P25 of Degussa) has been investigated. Pd was added in a nano-metallic form. The catalyst composition was also different from similar studied catalysts. This results in a better selectivity towards acetic acid formation. The reaction was carried out in a tubular reactor at temperature range 225–275 °C, total pressure range 0–200 psig and oxygen percentage in the feed gas of 10–40%. The feed gas contains ethane and oxygen. In this work, we develop a kinetic model for the reaction for the developed catalyst. In this model, we assume that oxidation reactions take place on different sites; ethane oxidation takes place on one site, ethylene oxidation on another site, and CO is oxidized to CO₂ on a third site. The model exhibits good agreement with the experimental data.

乙烷部分氧化为乙酸的反应动力学

已经研究了在负载的MoVNbPd / TiO ₂（Degussa的P25）上乙烷部分氧化为乙烯和乙酸。以纳米金属形式添加Pd。催化剂组成也不同于类似的研究催化剂。这导致对乙酸形成的更好的选择性。反应在管式反应器中于225–275°C的温度，总压力范围0–200 psig的条件下进行，进料气中的氧气百分比为10–40％。进料气体包含乙烷和氧气。在这项工作中，我们为开发的催化剂开发了动力学模型。在这个模型中，我们假设氧化反应发生在不同的位置。在一个位置发生乙烷氧化，在另一个位置发生乙烯氧化，CO被氧化为CO ₂在第三个网站上。该模型与实验数据吻合良好。
