Heat and mass transfer in hydrogen production by electrolysis of a water-coal suspension

The possibility of electrochemical gasification of a water-coal suspension at a temperature of 180–460°C and a pressure of 7–20 MPa has been proved experimentally. The obtained producer gas contains mainly hydrogen and carbon dioxide as well as traces of methane, propane, and carbon monoxide. After...

Description
Summary:The possibility of electrochemical gasification of a water-coal suspension at a temperature of 180–460°C and a pressure of 7–20 MPa has been proved experimentally. The obtained producer gas contains mainly hydrogen and carbon dioxide as well as traces of methane, propane, and carbon monoxide. After washing carbon dioxide with weak alkaline solutions hydrogen is dispatched for use in power engineering. The liquid phase contains an insignificant amount of hydrocarbons. Heat and mass transfer between reacting media in the electrolyzer under the conditions of phase transitions with partial absorption of the formed gases has been considered.
