Pretreatment an overview ScienceDirect Topics

Some pretreatment methods have been more commonly investigated than others, such as steam pretreatment, dilute-acid pretreatment, wet oxidation and AFEX. Dilute-acid pretreatment is performed by soaking (or by spraying) the material using a dilute acid solution and then by heating to temperatures between 140 and 200 °C for a certain time (from several minutes up to an hour).

The role of pretreatment in improving the enzymatic

However, the physical and chemical structure of lignocellulosic materials forms strong native recalcitrance and results in relatively low yield of ethanol from raw lignocellulosic materials. An appropriate pretreatment method is required to overcome this recalcitrance. For decades various pretreatment processes have been developed to improve the digestibility of lignocellulosic biomass.
