“…The film was uniform, with a thickness varying from 60 to 65nm all over the substrate. This method was used for catalyst preparation [107] and also to deposit an intermediate oxide layer before zeolite deposition on microstructured reactors [108].…”

“…The advantage of a directly grown zeolite layer compared to the dip-coated support, is that a complete coverage of an oriented zeolite crystal layer can be achieved [158,156]. The preparation of directly grown MFI zeolite coatings on catalytic supports is largely reported [159,160,108]. The method is similar to sol-gel technology.…”

“…Small crystals of zeolite were synthesised to favour a better contact between the metal foil and the zeolite coating. In the case of Mies et al [108], molybdenum-containing plates were coated with ZSM-5. Different pretreatments, including chemical etching, ALD of TiO 2 and Al 2 O 3 , UV treatment of the TiO 2 layer, the use of a solution of templating agent.…”

“…The synthesis protocols and the scaleup procedure to obtain identical zeolitic coatings on 72 substrates are reported elsewhere. 5 The as-synthesized coatings were calcined and subsequently subjected to an ion exchange procedure in a 1 × 10 -4 M cobalt acetate solution to obtain Co-ZSM-5 coatings. 6 A total weight of 4.5 mg of Co-ZSM-5 was obtained per plate.…”

In this paper, the results of computational fluid dynamics simulations of flow, temperature, and concentration distributions used in the design of a microreactor for the high-throughput screening of catalytic coatings (Mies et al., Chem. Eng. J. 2004, 101, 225) are compared with experimental data, and good agreement is obtained in all cases. The experimental results on flow distribution were obtained from laser Doppler anemometry measurements in the range of Reynolds numbers from 6 to 113. The measured flow nonuniformity in the separate reactor compartments was below 2%. The temperature distribution was obtained from thermocouple measurements. The temperature nonuniformity between the reactor compartments was below 3 K at a maximum heat production rate of 1.3 W in ethylene oxidation at 425 °C over CuO/Al2O3/Al coatings. With respect to concentration gradients, a deviation from the average rate of reaction of only 2.3% was obtained at realistic process conditions in the ethylene ammoxidation process over identical Co−ZSM-5 coatings in all reactor compartments. The cross talking noise between separate compartments does not exceed 0.1% when the reactor parts have a smooth surface finish. This illustrates the importance of ultraprecision machining of surfaces in microtechnology, when interfaces cannot be avoided.

“…The reactions can be performed either using a (i) catalyst particles in a micro fixed bed configuration [2,25], (ii) magnetically-supported catalysts held at the reactor walls with magnetic field [26][27][28][29], (iii) introducing a slurry of solid catalyst particles into the reactant flow [30], (iv) catalytic wall coatings obtained via hydrothermal synthesis [31,32] or methods derived from dipcoating, spincoating or washcoating [33][34][35][36][37][38][39]. Micro fixed bed reactors with a typical pellet size below 100 m seem to offer a simple way of catalyst introduction and they are suitable for any catalyst.…”
