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.
