Abstract

To reduce the amount of fuel and raw materials used, and to reduce the amount of water vapor used by reducing the molar ratio of carbon to carbon from 1.6: 1 to 2.5: 1, increasing the fraction of carbon monoxide in the synthesis gas, which is useful as a synthetic raw material such as high alcohol. It relates to a method for producing syngas.
