Development of a bioprocess for murine dimeric IgA production

Monoclonal IgA was produced under serum free conditions by a murine hybridoma cell line (ZAC3) in a hollow fiber, a continuous stirred tank and a fluidized bed reactor. Differences in the antibody adsorption to DEAE chromatog. matrixes, an essential step i ...

Development of a continuously operated reactor for the limited hydrolysis of whey protein by trypsin

Albert Renken, Antoine Margot

A continuously operated reactor was developed for the limited hydrolysis of whey protein using sol. trypsin. It consisted of a stirred tank followed by a tubular device. A stirred tank was used because it allows pH control to be achieved more easily. The t ...

Réacteur continu à écoulement segmenté pour la synthèse de poudres minérales par précipitation

Paul Bowen, Jacques Lemaître, Nathalie Jongen

A process for the production of powders by precipitation from a liquid reaction mixture comprises passing along a tubular reactor a segmented reaction flow comprised of discrete volumes of the reaction mixture separated by discrete volumes of a separating ...

Periodic operation of catalytic reactors -introduction and overview

Albert Renken

A review, with 89 refs., is presented on the subject of periodic operation of catalytic reactors by compn. forcing. Possible objectives of this mode of reactor operation are increased conversion, improved selectivity, reduced catalyst deactivation and insi ...

Direct dehydrogenation of methanol to formaldehyde in a circulating fluidized bed

Albert Renken

The direct dehydrogenation of MeOH to CH2O is presented. For the first time a circulating fluidized bed was used, which is very suitable because of its great heat transfer coeff. [on SciFinder (R)] ...

In-situ drift spectroscopy in a continuous recycle reactor: a versatile tool for catalytic process research

Albert Renken

Diffuse Reflectance IR Fourier-Transform (DRIFT) spectroscopy is an increasingly popular technique in catalysis research as it permits in situ observation of the reactor bed in powd. or granular form. However, DRIFTS in its conventional form suffers from t ...

Process development for the hydrolysis of lactose in whey by immobilized lactase of Aspergillus oryzae

Albert Renken

Immobilized lactose of A. oryzae was used for the hydrolysis of lactose in partially deproteinized whey in a fluidized-bed reactor packed with motionless mixers. The lactase was immobilized on chitosan-coated silica gel particles by means of glutaraldehyde ...

Engineering Aspects of Fluidized Bed Reactor Operation Applied to Lactose Treatment of Whole Whey

Albert Renken

An interesting possibility for the use of lactoserum in human nutrition is the hydrolysis of lactose to glucose and galactose, sugars which exhibit a better digestibility, a higher solubility, and which have a greater sweetening power than lactose. The hyd ...

Development of a tubular recycle membrane reactor for continuous operation with soluble enzymes

Albert Renken

The performance of steady-state flow ultrafiltration membrane reactors can be considerably increased by improving their hydrodynamic characteristics. A tubule recycle membrane reactor was designed and constructed. This type of reactor approximates plug flo ...
