compare the digestibility of lignocellulosic biomass, advantages, and disadvantages in acid pretreatment and alkaline pretreatment

Expert Solution

Comparison of different pretreatment of lignocellulosic biomass

Acid pretreatment	Alkaline pretreatment
Short duration of reaction	Longer than acid hydrolysis
Lesser residence time	Carbohydrate polymerization is reduced
removal of lignin and solubilization of hemicellulose	Reduction of cellulose crystallinity
very high glucose yield	Very effective removal of lignin
Increased chance of corrosion of containers for reaction process- costly instruments and reaction vessels are required.	Softwood digestibilty enhancement is low
costly acids are required for recovery.	need costly alkaline catalyst
Inhibitory sugars are formed as resultants or products of reaction	Less amount and number of inhibitors are only formed
Byproducts are degraded	lignin structure is altered

Maximum differences noted from various papers are included in the table. Please do not hesitate to give thumbs up. Happy learning. All the best. Stay safe.
