High Throughput Experimentation

The high-throughput experimentation technique was used to verify the testing conditions due to the effects of catalyst structure modifications and/or due to reaction parameter variation in parallel. In this paper, the design of experiment and catalytic results are discussed in the development of selective oxidation catalyst, to demonstrate the importance and versatility of such technology. It is used for the automated parallel testing of selective oxidation of propane to acrylic acid over some types of multi metal oxide catalysts. The catalysts used for performance test were Mo (molybdenum), cat-1 (unsupported Mo1V0.3Te0.23Nb0.125O), and cat-2 (supported Mo1V0.3Te0.23Nb0.125O). All catalysts were dried using spray drier. The effect of some reaction parameters, such as the amount of oxidant, presence of steam and reaction temperature was also investigated during the test. The configuration of the ‘nanoflow’ is shown to be suitable to screen catalytic performance. The results obtained gave very good reproducibility.

<p>The use of high throughout and combinatorial experimentation is becoming commonplace in catalytic research. The benefits of parallel experiments are not only limited to reducing the time-to-market, but also give an opportunity to study processes in more depth, by generating more data. To investigate the complete parameter space, multiple experiments must be performed and the variability between these experiments must be quantifiable. In this project, the reproducibility and variance in high throughput catalyst preparation and parallel testing were determined. High-performance equipment was used in a catalyst development program for fuel processing, the production of fuel cell-grade hydrogen from hydrocarbon fuels. Four studies, involving water-gas shift conversion and high-temperature steam methane reforming, were performed to determine the reproducibility of the workflow from automated catalyst preparation to parallel activity testing. Statistical analyses showed the standard deviation in catalytic activities as determined by conversion, to be less than 6% of the average value. Copyright © 2017 BCREC GROUP.

Adsorption Desorption

The Adsorption – desorption is considered as one of the most promising VOCs treatment technologies due to its cheap operational cost and low energy consumption. However, there are a huge amount of adsorbed VOCs released in desorption process. That is the reason why this study focused on the combination of adsorption-desorption with catalytic oxidation to treat completely VOCs as toluene. The adsorption catalyst MnCoCe/AC (metal oxide catalyst MnO2-Co3O4-CeO3 on Actived carbon) and oxidation catalyst Au/MnCoCe (Au supported on metal oxide catalyst MnO2-Co3O4-CeO3) were investigated and characterized by SEM - EDX, BET. The catalytic activity test were carried out on a micro-flow reactor system connected with GC online using a TCD detector.The results shown that Au/MnCoCe is a potential catalyst for the complete oxidation of toluene with the temperature for 100% toluene conversion of 300oC. The combination of adsorption-desorption  with catalytic oxidation decreased the temperature for 100% toluene conversion to 250 oC.

Excellent Catalytic Performance

AbstractSmall amount of different nickel precursors (nickel nitrate or nickel molybdate) were incorporated into MoBi-based catalyst to produce a series of modified composite oxides catalysts for the selective oxidation of isobutene (IB) to methacrolein (MAL). Nickel nitrate introduction can effectively improve IB conversion and nickel molybdate introduction can remarkably enhance the selectivity of MAL. The XRD results show that nickel introduction has some influence on the catalyst structure. The catalyst modified with NiMoO4 showed the highest MAL yield of 87.8%. According to the H2-TPR, BET and XPS results, the catalyst modified with NiMoO4 exhibits lower reduction temperature, higher pore volume and better lattice oxygen mobility, which were confirmed to be responsible for excellent catalytic performance for the title reaction. In the case of an excess of O2, an empirical kinetic model was used to evaluate the rate data. The activation energy (Ea) was found to be 172.4 kJ mol−1.
