FIELD: chemistry.
SUBSTANCE: method includes burning an expanded exhaust from a turbine and a first fuel inside a first reformer to produce spent gas. Hydrocarbon is reformed in the first reformer to produce reformed hydrocarbon. Heat is transferred from the spent gas to a first medium. A cooling apparatus is powered by heat energy from the heated first medium and cools a second medium. Heat is transferred from one or more oxidants to the cooled second medium to produce cooled first and second oxidants. The cooled first oxidant and second fuel are fed into a gas turbine unit to produce expanded spent gas from the turbine and mechanical energy. The cooled second oxidant is compressed in a compressor which is actuated by the mechanical energy. The compressed second oxidant and the reformed hydrocarbon are fed into a second reformer to produce synthesis gas.
EFFECT: high output of synthesis gas and products therefrom.
