| Abstract: | Coal gasification with in situ CO2 capture is believed to be able to produce highly concentrated H2 with little or no CO2 compared with the conventional process. This has been demonstrated by other researchers working on a single fluidised bed by continuously feeding the CaO sorbent. This work presents the results of coal gasification with in situ CO2 capture by a synthetic CaO sorbent in a 1 kWth dual fluidised-bed reactor at atmospheric pressure, which has not been reported in the literature. The synthetic CaO sorbent is cyclically used by going through multiple carbonation/calcination cycles during coal gasification. |
