Table 2 Volatile, char and ash content of bioenergy feedstocks: high-lignin endocarp tissue versus perennial grasses and woody biomass feedstocksa
Feedstock | Volatile (wt%) | Char (wt%) | Ash (wt%) |
|---|---|---|---|
High lignin (drupe endocarp) | 77.0% | 23.0% | None |
Medium lignin 1 (switchgrass) | 82.7% | 17.3% | None |
Medium lignin 2 (Poplar) | 79.6% | 20.4% | < 0.5% |
Low lignin (tobacco) | 78.9% | 21.1% | 3.9% |
Moderate lignin (Arabidopsis) | 76.7% | 23.3% | 3.1% |
