Abstract

Char and soot characterizationwas performed on samples obtainedfrom pilot-scale entrained flow gasification of coal bio-oil slurry(CBS) and coal/water slurry (CWS) at different operating conditions.The compositions and gasification reactivity of char and soot havebeen investigated to reveal the difference of CBS and CWS slurries.The results show that both char and soot obtained from CBS gasificationcontain alkali and alkaline earth metals which come from the bio-oil.These CBS char and soot alkali-containing samples exhibit higher gasificationreactivity than those from CWS gasification. For CBS gasification,soot has higher gasification reactivity compared with char. The gasificationreactivity may be caused by the catalytic effect of KCl and K₂SO₄ existing in char and soot. The reactivity ofchar and soot is also influenced by the gasification conditions (suchas H₂O/C ratio), and high CO₂ gasification reactivityis observed for chars exposed to high H₂O/C ratios in theentrained flow reactor.
