摘要 为了充分利用瓦斯资源,对瓦斯液相催化氧化制甲醇的反应溶剂和催化剂进行了研究和筛选,并讨论了反应温度和时间对瓦斯部分氧化反应的影响。结果表明,瓦斯在酸性条件下可发生选择性氧化反应生成甲醇,且溶剂酸性越强,目标产物的生成量越高;在CH3COOH水溶液作溶剂时,Pd(OAc)2-对苯醌-CO用作瓦斯部分氧化合成甲醇的催化剂体系较合适;延长反应时间和适当升高反应温度,有助于目标产物的生成。此外,还分析了瓦斯选择性氧化合成甲醇的反应机理。该研究为防治瓦斯事故,减少因瓦斯排放引起的温室效应及合理利用瓦斯资源提供了理论依据。 Aimed at a fuller use of mine gas resource,this paper describes the way in which the reaction solvent and catalyst system for the partial oxidation of mine gas to methanol are screened and introduces the effect of reaction temperature and time on the methane partial oxidation reaction.The results show that mine gas is subjected to selective oxidation in acidic conditions to form methanol and the stronger acidity of the reaction solvent leads to the higher yield of target product.Choosing CH3COOH solution as solvent allows the Pd(OAc)2-p-benzoquinone-CO system to be a suitable catalyst system for partial oxidation of mine gas to methanol.A longer reaction time and appropriate rise in reaction temperature facilitate the production of the objective products.The paper also discusses the reaction mechanism in which mine gas subjected to selective oxidation forms methanol.This study provides a theoretical basis for preventing gas accidents,reducing greenhouse effect caused by gas emission,and utilizing mine gas resource.
