The stoichiometry calculator above shows the mole ratios/coefficients of the balanced equation, 4NH3 + 5O2 = 4NO + 6H2O. Enter the amount of any of the substances to determine the ideal amounts to maximize the theoretical yield of the reaction. To find the limiting and excess reagents when...
在原工艺中,化合物6在ACN/H2O体系中溶解度不好,因此flow工艺中偶尔会遇到管路堵塞现象。AbbVie认为CN杂质数据波动的原因也是由于这种堵塞现象,酰胺与过量的丙烯酰氯反应生成了氰基杂质。为了改变这种不可控的工艺,他们筛选了溶剂体系,最后选用THF/H2O体系作为溶剂(Scheme12)。先将酒石酸盐7游离得到freebase6,fre...

近日,北京科技大学唐晓龙教授团队于化工领域顶级期刊Chemical engineering journal(中科院一区,IF=16.744)上发表题为“Recent advances in NO reduction with CO over copper-based catalysts: reaction mechanisms, optimization strategies, and anti-inactivation measures”的综述文章。该论文系统总结了Cu基催化剂催化CO+NO...
nm reacts with water according to NO2*+H2O→HONO+OH. However, the estimated kinetic constant for this process in the gas phase is quite small (k≈10?15–3.4×10?14?cm3?molecule?1?s?1) suggesting minor atmospheric implications of the formed radicals. In this work, ab initio molecular ...
由于反应中生成的H2O可能导致L酸向B酸转化,且该转化受反应温度影响,因此不同酸性位机理可能没有本质区别, SCR反应关键是NH3吸附位的氧化性. SCR活性取决于NH3在催化剂表面的吸附量和阶段氧化程度. 催化剂应能吸附足够的NH3, 这与其表面酸碱性有关; 吸附的NH3要能被活化脱氢且程度不宜太高,这与表面氧化还原性有...
Reaction of NO2, NO, O2, and H2O to form HNO2 «on:January 06, 2018, 09:51:30 PM » This is translated from a different language, so the nuances of the problem might be altered, but the essentially, the problem is this: ...
realizable k-ε turbulence model, discrete ordinates radiative heat transfer model and steady flamelet combustion model together with the chemical reaction mechanism of diesel fuel (C10H22) have been applied. NOx modeling has been performed via post-proc...
