From: Impact of moisture content on instant catapult steam explosion pretreatment of sweet potato vine
Pretreatment | Biomass | Sugar yield | Advantage | Disadvantage | Refs. |
---|---|---|---|---|---|
Ionic liquid | Switchgrass | 70% | Decrease the cost of ionic liquid pretreatment | The existence of water will hamper the efficiency of pretreatment | Shi et al. (2014a) |
Grinding | Wheat straw, corn stover etc. | NA | NA | Result in additional energy requirement and higher final particle size | Barakat et al. (2015) |
Supercritical CO2 | Southern yellow pine | 84.7% | The increase of initial moisture content will obtain higher final sugar yield | NA | Kim and Hong (2001) |
Steam explosion | Corn stover | 90% | Improve the sugar yield | Not benefit for the quickly heating of biomass during pretreatment | Sui and Chen (2015) |
Ammonia fiber steam explosion | Corn stalk | 80% | Increase of moisture content does not hamper the enzymatic hydrolysis of lignocellulose | Ditto | Moniruzzaman et al. (1997) |
Steam explosion | Softwood | 60–90% | Prompt the enzymatic hydrolysis and reduce the hydrolysis of hemicelluloses content | Ditto | Cullis et al. (2004) |
Acid steam explosion | Corn stover | >Â 90% (Xylose) | High soluble sugar yield | Ditto | Emmel et al. (2003) |
