| Abstract
| - We examined the gasification of cellulose, xylan, and lignin mixtures in supercritical water at623 K and 25 MPa. Our results indicate that the lignin content significantly affects the amountand composition of the product gas. Thus, we surmised that cellulose or xylan is likely to functionas a hydrogen donor to lignin. A set of equations developed to estimate the amount and composition of the product gas accurately predicted the actual results using only the lignin fractionas a parameter. This confirmed the importance of the lignin fraction effect on supercritical watergasification characteristics.
