[交流] [有奖回答] 关于甲烷选择氧化生成甲醇的问题

另外一个想法：
将你的催化反应过程拆成两步（第一步，将甲烷部分氧化制成合成气；第二步，将合成气制成甲醇；）这主要是基于热力学的考虑，两个反应的最佳反应温度还是有一定的差距，且最佳的反应催化剂也会有差 ...

Project title: Propane and Isobutane oxidations to (meth) acrylic acidsSummary


Selective oxidation of propane to acrylic acid and isobutane to methacrylic acid using formulations based on multicomponent mixtures  of Mo, V, Nb, Te, Sb, Ta, Ge, alkali metals and transition metals containing organic inorganic material for low temperature oxidations prepared by solvo thermal and hydrothermal synthesis techniques. The controlled variation of the crystal structure, the morphology, and the chemical composition allows deriving quantitative structure-activity relationships that will help designing the next generations of catalysts and adapted operating conditions.

Potential catalysts are investigated by means of in situ IR and RAMAN spectroscopy monitoring the interaction with propane/propene and isobutane/isobutene with surface functional groups functional species under the respective reaction conditions. Physico-chemical characterizations like the X-ray diffractograms, BET specific surface area, chemical composition, SEM, TEM, XPS and the acidic (adsorption/desorption of ammonia) and the basic properties (adsorption of CO2) and the redox properties (adsorption/desorption of O2, temperature programmed reaction with propane/isobutane) are also carried out.
