Microreactors as tools for chemical research
نویسندگان
چکیده
The unique operational characteristics of microreactors are described in this article, with particular reference to their use as tools for chemical synthesis. With reference to the future automation, an example is presented to illustrate how microreactors can be readily integrated into current HPLC systems, to enable fully integrated chemical synthesis and product analysis to be performed.

Ultrasound-Assisted Biodiesel Production in microreactors
The ultrasound-assisted (UA) soybean oil methanolysis using KOH as a catalyst was studied at different reaction conditions in a microreactor. Box–Behnken experimental design, with three variables, was performed and the effects of three reaction variables i.e. reaction temperature, catalyst concentration and the methanol-to-oil molar ratio on fatty acid methyl ester (FAME) yield were evaluated b...

متن کاملA CFD Simulation of Hydrogen Production in Microreactors
In this study, the modeling of hydrogen production process in microreactors by methanol-steam reforming reaction is investigated. The catalytic reaction of methanol-steam reforming producing hydrogen is simulated considering a 3D geometry for the microreactor. To calculate diffusion among species, mixture average correlations are compared to Stephan-Maxwell equations. The reactions occurring in...
متن کاملFine structuration of low-temperature co-fired ceramic (LTCC) microreactors.
The development of microreactors that operate under harsh conditions is always of great interest for many applications. Here we present a microfabrication process based on low-temperature co-fired ceramic (LTCC) technology for producing microreactors which are able to perform chemical processes at elevated temperature (>400 °C) and against concentrated harsh chemicals such as sodium hydroxide, ...
متن کاملThermo-fluid Design Approach to Microreactors with Uniform Temperature and Residence Time Distribution
Recently, extensive studies have been carried out on micro chemical process technologies (Jensen, 2001; Fletcher et al., 2002). In particular, analysis of chemical reactions and transport phenomena in micro-space has been performed energetically. However, most microreactors are designed and fabricated by trial and error -there is no systematic procedure for developing microreactors. Therefore, ...
