Chemistry is an experimental science, Quality Control of: Tetrapropylammonium bromide, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1941-30-6, Name is Tetrapropylammonium bromide
A series of Na-ZSM-5 zeolite supported Pd catalysts with different Si/Al ratios (Si/Al = 20, 40 and 80) were synthesized. And the effect of different Si/Al ratios on the catalytic combustion of VAM (with methane concentration below 1%) was investigated. The Pd/Na-ZSM-5-40 shows the best catalytic activity for VAM as to catalytic test. Through various techniques (XRD, SEM, HRTEM, XPS, H2-TPR and NH3-TPD), it is found that the advantage physicochemical properties of Pd/Na-ZSM-5-40 compared with Pd/Na-ZSM-5-20 and Pd/Na-ZSM-5-80: good dispersion and relatively small particle size of Pd particles, higher PdO and surface oxygen content, strong interaction between the active Pd species and the Na-ZSM-5 supports and more surface acid sites are all beneficial to methane oxidation. Furthermore, the CH4 conversion of Pd/Na-ZSM-5-40 at different GHSV (16000?112500 mL g?1 h?1) were remained after running for 50 h, suggesting a good stability.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Quality Control of: Tetrapropylammonium bromide, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1941-30-6, in my other articles.
