Combined Coal Gasification and Methane Reforming for Production of Syngas in a Fluidized-Bed Reactor

---

The concept of combining coal gasification and methane reforming for syngas production in a
fluidized-bed reactor, as a means for utilization of both coal and coal-bed methane, was proposed
and evaluated experimentally. Preliminary experiments were performed in a laboratory-scale
fluidized-bed reactor operating at 1000 °C, using two Chinese coals: a bituminous coal (Coal
A) and an anthracite (Coal B). To demonstrate combined coal gasification and methane reforming,
the reactor was fed with 1.5-2.5 kg/h coal, 0.4-0.5 Nm3/h methane, 1.45-2.0 Nm3/h oxygen, 0.4
Nm3/h air, and 2.0-2.4 kg/h steam. Up to 90% methane conversion and 70% carbon conversion
were achieved, and the resulting syngas had a composition of 35%-39% H2, 31%-34% CO, and
20%-22% CO2, balanced by N2. For comparison, the results of the gasification of Coal A and
Coal B without added methane were also reported. These results proved the feasibility of such
an integrated coal gasification and methane reforming process. Further kinetic studies and process
development opportunities were also identified.
