NO2还原O2/CO2燃烧碱金属准东煤The influences of reaction temperature,ash,minerals and reaction atmosphere on the NO2 reduction behavior were investigated in a fixed bed reaction system to explore the mechanism of NO2 reduction under O2/CO2 combustion condition.Experimental results indicate that NO2 ...
设计可以共吸附并还原 CO2 与 NO-3 / NO-2 的材料是电催化合成尿素所面临的的关键 挑战. 前期研究表明引入缺陷和 / 或掺杂异质原子等方式是改善催化剂电子结构,实现 CO2 和 NO-3 / NO-2 共吸附,提升尿素合成效率的有效方式. 针对尿素合成的机理,报道最多的是由∗CO 和 ∗NH2中间体或∗COOH 和∗...
In situ measurements of the negative ions have not yet been performed and so ion chemical modelling is relied upon, which indicate that nitrite anions, NO2?, are important. Thus, in the present work the gas phase reaction of NO2? with carbon dioxide molecules, CO2, has been studied at ...

最有希望的缺陷MXene是含有Hf空位的Hf2NO2,具有0.45 V的低过电势。更重要的是,通过电子结构分析可以观察到,在存在空位时,MXenes的费米能级发生了显著的变化,这表明费米能级的变化,可以作为一种理想的描述符,来快速预测缺陷MXenes的催化性能。这种评价策略,适用于MXenes及以外其他的催化剂,这可以增强高通量筛选工...
Instead, the occupation of the open metal sites is governed by kinetics, whereby the interaction of the guest molecules with the MOF organic linkers controls the reaction barrier for molecular exchange. Specifically, the displacement of CO2 adsorbed at the metal center by other molecules such as ...
废物流,特别是各种燃烧气体的废物流,可以包含一种或多种另外的非co2组分,仅例示地如水、nox(一氮氧化物:no和no2)、sox(一硫氧化物:so、so2和so3)、voc(挥发性有机化合物)、重金属(例如但不限于汞)、以及微粒物质(悬浮在气体中的固体或液体颗粒)。烟道气温度也可以变化。在一些实施方案中,包含co2的烟道气...
II. Estimation of kinetic parameters of the stages involving NH2O2, HNOOH, and NH2O This work extends the first part of the study [Fizika Goreniya i Vzryva, 30 , No. 1, 60–65 (1994)] of the kinetic mechanism of the reaction of NH 2 with O 2 . The rate constants of possible ...
1.1.6. Chemical absorption Chemical absorption involves the reaction of CO2 with a chem- ical solvent to form a weakly bonded intermediate compound which may be regenerated with the application of heat pro- ducing the original solvent and a CO2 stream (IPCC, 2005). The selectivity of this ...
C3H5(NO3)3 + O2 = CO2 + H2O + NO2 is a Combustion reaction where four moles of Nitroglycerin [C3H5(NO3)3] and eleven moles of Dioxygen [O2] react to form twelve moles of Carbon Dioxide [CO2], ten moles of Water [H2O] and twelve moles of Nitrogen Dioxide [NO...
