| 摘要 |
The present invention relates to a method for reducing carbon dioxide emissions while increasing the amount of manufactured synthesis gas in a system for manufacturing synthesis gas using coal gasification. According to the method, power generation and chemical material production are increased by using part of carbon dioxide, which is captured in a coal gasification system, in manufacturing synthesis gas via dry reforming with methane, which is supplied from the outside separately, and adding the synthesis gas to synthesis gas manufactured by the coal gasification system. Energy necessary for dry reforming can be minimized by recovering heat from the synthesis gas at temperature of 1200°C or higher being discharged from the coal gasification system instead of receiving energy, which is necessary for the endothermic dry reforming reaction at temperature of 700°C or higher, from the outside. |
