Membrane reactor microstructured by filamentous catalyst

Chemically-modified cellulose paper as a microstructured catalytic reactor.

We discuss the successful use of chemically-modified cellulose paper as a microstructured catalytic reactor for the production of useful chemicals. The chemical modification of cellulose paper was achieved using a silane-coupling technique. Amine-modified paper was directly used as a base catalyst for the Knoevenagel condensation reaction. Methacrylate-modified paper was used for the immobiliza...

Novel design of a microstructured reactor allowing fast temperature oscillations

Two types of stainless steel microstructured reactors for catalytic gas-phase reactions have been developed and characterized with respect to heir thermal behaviour under non-stationary temperature conditions. One of the reactors used (FTC-I) allowed periodic temperature changes up to 00 K with a frequency of 0.05 Hz. However, a broad temperature gradient of 80 K developed inside the reactor. A...

A packed bed membrane reactor for production of biodiesel using activated carbon supported catalyst.

In this study, a novel continuous reactor has been developed to produce high quality methyl esters (biodiesel) from palm oil. A microporous TiO2/Al2O3 membrane was packed with potassium hydroxide catalyst supported on palm shell activated carbon. The central composite design (CCD) of response surface methodology (RSM) was employed to investigate the effects of reaction temperature, catalyst amo...
