Title: Process of producing methanol
Inventor: KONIG PETER
IPC: C07C29/151
Filed: 1995-05-09
Granted: 2005-10-18
Abstract: From a synthesis gas which contains hydrogen and carbon oxides, methanol is produced on copper-containing catalysts under pressures in the range from 20 to 120 bars and at temperatures in the range from 200 to 350°C. The synthesis gas is passed through a first synthesis reactor, which consists of a shaft reactor and contains a fixed bed of a copper-containing catalyst. The reaction in the shaft reactor is carried out adiabatically and without a recycling of synthesis gas. Together with recycle gas, the gas mixture which has not been reacted in the first synthesis reactor is passed through a second synthesis reactor, which contains a copper-containing catalyst, which is disposed in tubes and is indirectly cooled through boiling water. 10 to 30% of the carbon oxides of the synthesis gas are reacted in the shaft reactor to form methanol.
