2?PRODUCTION OF SYNGAS USING RECYCLED COVIA COMBINED DRY AND STEAM REFORMING OF METHANE

A process wherein CO2, methane, and steam react at high temperatures, for instance approximately 1600° C., to form a synthetic gas or syngas. This syngas can then be used in a methanol production plant. The carbon dioxide used to produce the syngas may also comprise recovered emissions from the prod...

More Information
Summary:A process wherein CO2, methane, and steam react at high temperatures, for instance approximately 1600° C., to form a synthetic gas or syngas. This syngas can then be used in a methanol production plant. The carbon dioxide used to produce the syngas may also comprise recovered emissions from the production of methanol or urea, such that CO2 is recycled. The rich syngas is produced by the bi-reforming of methane, featuring a combination of dry reforming of methane and steam reforming of methane, via the reaction CO2+3CH4+2H2O→4CO+8H2, such that the H2:CO ratio is 2. A plasma reactor may be provided for the reaction. Excess heat from the syngas may be used for heating the water that is used as steam for the reaction.
