Catalytic microreactors constitute a crucial technology for process intensification in the production of hydrogen, particularly for on-site and/or onboard applications intended to feed fuel cells. This chapter describes ...

Regular structures of SiO2 microneedles and Si micromonoliths have been formed using processing methods similar to those used in the microelectronics field; then these structures have been used as supports for zeolite ...

La problemàtica en les reaccions de policondensació, és que l'equilibri entre els reactius i els productes és establert ràpidament, i per tant, la producció del producte desitjat , un polièster, s'atura. Es planteja la ...

Stainless steel plates were coated with cobalt talc (Co3[Si2O5]2(OH)2) and used in a catalytic plate microreactor for producing hydrogen from ethanol steam reforming at low temperature. Cobalt talc was deposited successfully ...

Macroporous silicon disks containing ordered channels of 2 µm side and 0.2 mm length (9 × 106 channels cm-2) have been functionalized with a thin layer of Au/TiO2 and Pt/TiO2 photocatalysts and tested in the photoproduction ...

A quartz microreactor containing 28 microchannels of 500 µm width and 105 mm length has been used to photoproduce hydrogen from liquid water-ethanol using an Au/TiO2 photocatalyst and UV light. The photomicroreactor has ...

A novel design of a silicon-based micro-reformer for onboard hydrogen generation from ethanol is presented in this work. The micro-reactor is fully fabricated with mainstream MEMS technology and consists of an active ...

Process intensification is a new paradigm in Chemical Engineering, aiming at achieving sustainability in the process industry, so the world’s requirements for energy and consumer products are met without compromising ...
