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.
