Optimizing catalyst supports at single catalyst pellet and packed bed reactor levels: A comparison study

Using a catalyst support with optimal pore network and pellet structures is critical to the success of an industrial heterogeneous catalyst. This work optimizes the catalyst support of a dry reforming of methane catalyst at packed bed reactor level, that is, effects of concentration and temperature gradients in the reactor are accounted for. Meanwhile, the optimization at reactor level is also compared with that at single catalyst pellet level where fixed concentrations and temperature are imposed on the pellet surface. Results show that the optimal structures obtained at pellet level are similar to these acquired at reactor level, but the improvements in catalyst performance calculated at pellet level are overestimated. Therefore, when designing an industrial catalyst pellet, the preferred structures can be obtained from the optimization at pellet level, but the corresponding improvements in catalyst performance should be evaluated at reactor level to reflect the reality in industry.     

两种不同光谱类型的R-藻红蛋白的荧光性质研究

红藻中的R-藻红蛋白(R-PE)依照其吸收光谱可分为两种不同的光谱类型,即“双峰型”和“三峰型”.本文通过对不同pH条件下的R-PE的荧光光谱及荧光寿命的研究,发现“三峰型”R-PE的pH稳定范围较“双峰型”R-PE大.在R-PE浓度对荧光光谱的影响实验中,随着蛋白浓度的增加,荧光峰位置逐渐红移。荧光寿命逐渐增大,荧光强度先行增加而后减弱.用碘离子对其荧光进行猝灭,随着碘离子浓度的增大,荧光强度逐渐降低,荧光寿命逐渐缩短,并服从Stem-Volmer规则.     

Electrolyte wetting effects in the comparative polarization behaviour of the hydrogen evolution reaction at Ni-Mo-Cd electrodes in KF · 2HF and KOH · 2H2O melts

In the electrolyte process of fluorine production from KF · 2HF melts at 85° C, unusually high polarization arises both at the cell anodes (carbon) and cathodes (mild steel) at moderate current densities. The anomalous polarization behaviour in fluorine evolution at carbon anodes has been extensively studied but much less is known about the origin of hyperpolarization in hydrogen evolution at the cathodes. Here, the results of comparative polarization studies at a Ni-Mo-Cd composite cathode material in a KF · 2HF melt and a corresponding aquo-analogue melt of KOH · 2H₂O are reported. Large differences are observed which are attributed to the different wetting characteristics of these two melts at the interface of the Ni-Mo-Cd cathodes that are microporous. Such electrode material also offers a major improvement of cathode polarization over that at mild steel surfaces. Conclusions on wetting effects are based on: (i) a comparative determination of hydrogen-bubble contact angles at the electrode in the two melts and (ii) an evaluation of the double-layer capacitances of the electrode interfaces with the two melts as determined by the fast potential-relaxation method, at short times after current interruption. The apparent double-layer capacitances at a given electrode are very different in the two melts.     

Study of subbituminous coal chars: Effect of heat treatment temperature on their structural characteristics

Changes in the apparent surface area that are produced by carbonisation of a subbituminous coal at different temperatures are followed by adsorption of CO₂ at 273 K and 298 K, the Dubinin—Radushkevich equation being used. Activated diffusion effects are found for the char samples prepared at 973 and 1173 K. A maximum in the apparent surface area is found at 1073 K.     

Grundlagen der Blasenbildung an Einzelporen und Lochplatten

Basics on Bubble Formation at Single Pores and at Porous Plates Many processes in biotechnology (e.g., gas supply for fermentation vessels) and in process engineering (e.g., foaming with membranes) require the knowledge of how bubbles are formed at pores and at porous plates. Bubble build‐up at and release from the pores are both complex processes due to the constant change in bubble size, shape, and compressibility. The relevant literature to these processes is summarized here, and the bubble formation and bubble release processes in stationary and moving media are described. The factors that influence bubble formation and movement are deduced from the forces that act on a forming bubble. Empirical approaches from the literature are presented, which estimate the bubble size in dependence of the process parameters. Bubble formation depends on the one hand on the gas flow through the pores, on the other hand one has to distinguish between bubble formation in stationary and in moving media.

Temperature-dependent property development in hydrogels derived from hydroxypropylcellulose

Hydrogels constitute an important class of responsive materials that are employed in numerous biomedical and personal-care applications, most notably of which are controlled drug delivery, separations and superabsorbency. Since aqueous hydroxypropylcellulose (HPC) solutions exhibit lower critical solution behavior, hydrogels produced from this cellulose ether are temperature-responsive, swelling at low temperatures and contracting at high temperatures. If HPC hydrogels are synthesized at temperatures in the single-phase regime, they remain nonporous, whereas those crosslinked in the biphasic regime become microporous. In this work, we employ the modified temperature-induced phase separation (TIPS) protocol to generate nonporous and microporous HPC hydrogels crosslinked at different temperatures. The dynamic mechanical properties and swelling capacities of these hydrogels are reported as functions of crosslinking temperature.
