Converting coal to gas using gas solid reactions primarily featured the reaction of the carbon in coal with steam at pressures lower than 10 MPa and temperatures above 750°C. The coal gasification process would produce hydrogen, ammonia, methanol and hydrocarbons, and they were also used with steam to create synthetic natural gas (SNG).

Therefore in this work it is suggested to combine a coal gasification unit with a Graz Cycle power plant, an oxyfuel technology of highest efficiency. The firing of the syngas from coal gasification with pure oxygen avoids the expensive precombustion CO2 sequestration and leads to a working fluid of CO2 and steam, where CO2 is captured by simple steam condensation.

The inherent problem of coal gasification is the hightemperature required to achieve a practical rate of reaction of coal with steam. The temperature varies—depending on the reactivity of the coal and the choice of gasifier—from about 800 °C to 1650 °C (1500 °F to 3000 °F) for uncatalyzed gasification.

IGCC is a type of power plant that generates synthetic gas (syngas) from coal and then burns that syngas to power a gas turbine (similar to a jet engine). The heat from the gas turbine exhaust then generates steam to run a steam turbine. None of the basic technologies – coal gasification, gas turbines and steam turbines – are new.
