Stability of cellulose-based carriers in batch and packed-bed reactors

چکیده
Abstract: The selection of a suitable type of reactor for the reaction with enzymes immobilized on the carriers is extremely important to industry. In this study the possibility of using pre-selected cellulose-based carriers (Granocel) to conduct the reaction in a stirred batch reactor and a fixed-bed reactor was investigated. It was shown that non-activated Granocel did not undergo compression or crushing, so it was suitable for both types of reactors tested. Granocel activated with divinylsulphone can be used in the packed-bed reactor, but after earlier stabilization of the bed, and in the stirred reactor, but in a volume close to 50% of the reactor volume. Granocel activated with glutaraldehyde is not suitable for use in packed-bed reactors, because of its susceptibility to compression. It can be applied in a stirred reactor, but only in a volume close to 50% of the reactor volume.

In this study, immobilization of partially purified almond (Amygdalus communis) β-galactosidase on Con A layered calcium alginate-cellulose beads was investigated. Immobilized β-galactosidase retained 72% of theinitial activity after crosslinking by glutaraldehyde. Both soluble and immobilized enzyme exhibited the samepH and temperature optima at pH 5.5 and 50ºC, respectively. Howev...

The kinetics of cellulose hydrolysis under extremely low acid (ELA) conditions (0.07 wt%) and at temperatures >200°C was investigated using batch reactors and bed-shrinking flow-through (BSFT) reactors. The maximum yield of glucose obtained from batch reactor experiments was about 60% for α-cellulose, which occurred at 205 and 220°C. The maximum glucose yields from yellow poplar feedstocks were...

Chemical looping combustion is a promising technology for power production with integrated CO2 capture. High overall efficiencies can be reached, if the CLC reactors are operated at elevated pressures and high temperature, which can be accommodated in packed bed reactors. More possible oxygen carriers can be selected if the desired temperature rise for power production is achieved in a two stag...
