Abstract
An H2- and CO-containing synthesis gas is made by separating coke-oven gas from a coke-oven process into hydrogen and a residual gas stream containing hydrocarbons and obtaining a CO-rich synthesis-gas stream from a top gas of a blast furnace. The hydrogen separated from the coke-oven gas is fed into the CO-rich synthesis gas stream obtained from the top gas of a blast furnace to make the synthesis gas, and the hydrocarbon-containing residual gas stream is fed into the blast furnace as feedstock.
Claims6
A method of making an H2- and CO-containing synthesis gas, the method comprising the steps of:
- separating coke-oven gas from a coke-oven process into hydrogen and a residual gas stream containing hydrocarbons,
- obtaining a CO-rich synthesis-gas stream from a top gas of a blast furnace,
- feeding the hydrogen separated from the coke-oven gas into the CO-rich synthesis gas stream obtained from the top gas of a blast furnace to make the synthesis gas, and
- feeding the hydrocarbon-containing residual gas stream into the blast furnace as feedstock.
