fischer-tropsch synthesis is a promising route for production of light olefins via co hydrogenation over transition metals. co is one of the most active metals for fischer-tropsch synthesis. some different variables such as preparation parameters and operational factors can strongly affect the selectivity of fischer-tropsch synthesis toward the special products. in the case of preparation varia...

The purpose of this work is to develop a reasonably detailed dynamic model of a Lurgitype industrial methanol synthesis reactor so as to determine important simplifications, to identify application/operating model limits, and to preliminary check the feasibility for the Nonlinear Model Predictive Control (NMPC) methodology. To do so, a Partially Differential Equation (PDE) system is formulated ...

Titanium dioxide was applied as an immobilized photocatalyst in a microstructured falling film reactor for the continuous-flow C–H arylation of heteroarenes with aryldiazonium salts as the starting material. Detailed investigations of the catalyst and a successful long-term run proved its excellent usability for this process. Very good yields up to 99% were achieved with broad substrate scope a...

This paper introduces a novel fabless, polyurethane microfluidic reactor (PMR) for the production of magnetic nanoparticles using droplet-based flow. The PMR system is the most chemically robust polymer platform to date for nanoparticle synthesis; unlike other polymeric microfluidic platforms such as polydimethylsiloxane (PDMS), it does not absorb aqueous solvents, alcohols or organic materials...

ru/al2o3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of rucl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. the samples were characterized by tem, xrd and tpr techniques. the catalytic performance tests were carried out in a fixed-bed micro-reactor under different operating conditions. ethylene g...

in this research, the thin films of n-s doped titanium dioxide (tio2) were successfully prepared by simple sol-gel method in the presence of tetrabutylorthotitanate as a starting reagent. furthermore, titanium dioxide (tio2) was functionalized with thiourea. furthermore, n-s doped titanium dioxides (nsto) were fixed on glass balls by glass balls fixed-bed reactor system. besides, the effect of ...

UNLABELLED An integrated elastomeric microfluidic device, with a footprint the size of a postage stamp, has been designed and optimized for multistep radiosynthesis of PET tracers. METHODS The unique architecture of the device is centered around a 5-microL coin-shaped reactor, which yields reaction efficiency and speed from a combination of high reagent concentration, pressurized reactions, a...

Mathematical models, especially when coupled with modern computer techniques, prove to be very effective in searching for optimal operating conditions and creating an optimal microenvironment for the biocatalyst in order to optimise productivity. Therefore, the study of the theoretical model for the enzyme reaction system is of interest for the industrial application of the biocatalyst. Theoret...
