Abstract
Woody biomass was gasified in steam at high temperature (∼923K) and pressure (∼6.5MPa) in the presence of a CO2 sorbent using a batch reactor with 50cm3 capacity; this process is termed “in situ CO2 removal gasification.” Gas, tar, and char were obtained as the products. The evolved CO2 was completely absorbed in the sorbent, and no CO2 was in gas phase. The product distribution at different reaction temperatures ranging from 473 to 923 K was examined to obtain fundamental information on the biomass degradation during the gasification. The reaction model proposed by Shafizadih and Chin was applied. The kinetic constants of the primary and secondary degradations were calculated from the product distribution.
