INTRODUCTION

In a chemical reaction, the process of catalysis is the increase or decrease in rate of a chemical reaction (reaction kinetics) caused by a catalyst.
Nowadays, research and development of catalysts are extremely important in the chemical industry. It is thought that approximately 90% of industry-made chemical products involve some catalytic process in their processing.
One of the main characteristics of catalysts is that they are not consumed by the chemical reaction, although they may suffer some deterioration. This deterioration is due to the loss of their catalytic features. For that reason, it is important for the students to understand the immobilization of catalysts in the reactors, a fact that prevents them from being dragged by the final products.
The Computer Controlled Batch Enzyme Reactor “QREC” is a batch enzyme reaction unit designed to perform glucose isomerisation and analyse the glucose and fructose concentrations with a polarimeter.

EXERCISES AND PRACTICAL POSSIBILITIES TO BE DONE WITH THE MAIN ITEMS

1. Study of the principles of catalytic batch reactors.
2. Study of the type of enzyme in the specific activity of a catalytic batch reactors.
3. Determination of optical rotation of fructose and glucose.
4. Demonstration of Biot’s law.
5. Study of the principles of polarimetry.
6. Determination of the glucose and fructose concentration by polarimetry.
7. Study of the influence of different variables (solution concentration, reaction temperature, reaction pH) on enzyme activity.
8. Determination of Michaelis-Menten rate equation constants in a batch enzyme reactor.
9. Determination of the enzyme specific activity through Michaelis- Menten equation and Lineweaver-Burke plots.
10. Study of the principles of batch enzyme kinetics.
    Additional practical possibilities:
11. Sensors calibration.
    Other possibilities to be done with this Unit:
12. Many students view results simultaneously.
    To view all results in real time in the classroom by means of a projector or an electronic whiteboard.
