Optimum Temperature for Lactose Hydrolysis in Batch Reactors

In simple batch reactors, the initial enzyme concentration or loading can be increased to achieve faster or more complete hydrolysis, but the enzyme is expensive. Therefore, we may want to achieve the desired hydrolysis level with the minimum amount of enzyme loading possible.

Kinetics of formic acid-catalyzed cellulose hydrolysis .

Abstract. Hydrolysis is a reaction to produce sugars from lignocellulosic raw materials for biochemical production. The present study elucidates the hydrolysis of cellulose and formation of glucose decomposition products catalyzed by 5% to 20% (w/w) formic acid at 180 to 220 °C with an initial cellulose concentration of 10 to 100 g/L. Microcrystalline cellulose was used as a model compound.

Non-catalyticsteamhydrolysisoffatsandoils .

Hydrolysis products must be removed from the area of reaction to ensure a forward rate of reaction. A high degree of hydrolysis is ensured in the standard industrial process by using a large excess of water and withdrawing the aqueous glycerol-rich phase and replacing it with fresh water. High temperatures also accelerate hydrolysis [8].
