Ethanol production method from synthesis gas

摘要

The system and process for converting biomass to ethanol by synthesis gas. The present invention relates to a process and apparatus for synthesizing ethanol using synthetic routes by means of synthesis gas. A process and apparatus for gasifying biomass, such as biomass, in a steam gasifier employing a fluidized bed and heating, using hot combustion gases from synthesis gas combustion, are described. The processes and apparatus for converting synthesis gas to ethanol are also described using stepped catalytic reactions to convert carbon monoxide and hydrogen to ethanol using catalysts including iridium acetate.
