Abstract
In order to understand the changing CO2 sequestration potential, oil shale ashes were produced at a 60 kWth CFBC facility in oxy-fuel mode. The ash was treated with water and CO2 in order to mimic the ash treatment technology currently in use in the industry. The ash bound 81 kgCO2/tash it means that 6 % of the CO2 emitted would be bound at the ash fields. Due to decreased decomposition of carbonates, when using oxy-fuel CFBC, the CO2 specific emission of combustion would decrease by 5 % compared to regular CFBC and 19 % compared to PF. Decreased CO2 production would result in reduced CO2 transportation and further utilization or storage cost.
