Abstract:
The behavior of a downstream fixed-bed of porous particles (a mixture of activated alumina and charcoal) was investigated as a low-cost alternative for upgrading the pyrolysis gas released from a biochar production process (slow pyrolysis in a fixed-bed reactor). Results showed that both pressure and bed composition (in terms of charcoal mass fraction) had significant effects on the yield of producer gas, as well as on its composition. Both porous materials exhibited a relatively good performance in terms of tar removal. The best results (highest yield of gas and maximum H2 content) were obtained when the fixed-bed was composed entirely of charcoal and the absolute pressure was increased from 0.1 to 1.0 MPa.
