Based on experiments and DFT studies, CeO2-TiO2 catalyst was found to be deactivated by KCl or K2O, and the poisoning effect of K2O was more serious than that of KCl. The characterization results showed that compared with KCl, K2O could lead to a greater decrease in surface acidity, ...
Balance KCl3 + O2 = K2O + Cl3 Using the Algebraic Method Step 1: Label Each Compound With a Variable Label each compound (reactant or product) in the equation with a variable to represent the unknown coefficients. a KCl3 + b O2 = c K2O + d Cl3 Step 2: Create a System of ...
Additionally, it was noteworthy that the performance of the physical mixing catalysts showed different catalytic performance, due to different mole ratio of K2O and KCl. Though K2O and KCl were the main active components, there is a huge difference between the physical mixing catalysts and the ...

In laboratory tests, as-received high-duty and superduty fire-clay brick and 70% alumina brick treated with KCl-K 2 CO 3 mixtures showed no peeling at a temperature of 1600掳F. Cracks were found in high-duty brick that were treated with KCN at 1500掳F. under partially reducing ...
O-NaCl-B2O3 and K2O-KCl-B2O3 glasses]]>Absorption and emission spectra of two Na 2 O-NaCl-B 2 O 3 and two K 2 O-KCl-B 2 O 3 glasses, with large thallium concentrations (about 0.01 mol thallium per litre glass) have been studied. Absorption bands have been observed at 49 000, ...
