Development of a Two-stream Concept to Increase the Gasification Efficiency of the SCWG Process

Short Introductive summary

Previous experiments with dry biomass showed gasification rates of about 60% (conditions: T ~ 650°C, p = 28 MPa). Continuous operation was possible for up to 8 h, but the experiments had to be stopped due to the formation of solid deposits in the reaction system, containing salts and coke. In the present work, inner temperature measurements were conducted to determine the temperature range in which these deposits form. After successful temperature measurements, a new reaction system configuration was developed to reduce the amount of deposits formed. With this second configuration, operation of up to 100 h was possible. Gasification rates increased significantly to about 90%.
