Synthesis of chemicals and materials
There is an urgent need for novel climate-friendly routes for the synthesis of chemicals, catalysts, and materials. We are working on the production of basic chemicals such as hydrogen, synthesis gas, methane, methanol, olefins, acetylene, and ammonia. In most cases the process requires an appropriate catalyst and advanced reaction engineering. Chemical and physical models are developed that facilitate scale-up from laboratory to industrial scale.
In laminar flow chemistry, tubular reactors are often operated in the transition regime were neither the axial dispersion model nor the pure convection model are valid. This paper presents for solute transport under Poiseuille flow models for the residence time distribution (RTD) in the transition regime missing previously. …
