Production of ethanol from carbide production exhaust gases
Thread Content
The off-gases from calcium carbide production are rich in carbon monoxide, and ethanol is intended to be produced using a one-step process. Is the F-T synthesis method the one that can be industrialized at present? The key to Fischer-Tropsch synthesis lies in the choice of catalyst. Currently, there are rhodium-based catalyst systems and non-rhodium-based catalyst systems – which type of catalyst is more suitable for large-scale production? What is the status of the facilities and production capacity that have been built both domestically and internationally? Welcome to all marine friends for your analysis and advice.
It’s not appropriate, right? Is there enough hydrogen in the exhaust gas? Theoretically, ethanol can only be produced from one molecule of CO and at least two molecules of hydrogen, so it shouldn’t be cost-effective. Methanol can be considered, and then the dimethyl ether route can be used to produce ethanol; in this way, multiple products can all be obtained as outputs, which offers greater flexibility.

Nowadays, there is a biological fermentation process whereby microorganisms can metabolize CO in calcium carbide off-gases and hydrogen released from water to produce ethanol in one step. There are already commercial cases for producing ethanol from exhaust gases from CO-rich steel mills and alloy plants.
