     With reduced Cu as catalyst, 87% of the gas CO+H₂ is converted to CH₃OH at 250° and 100 atm.  S compounds, hydrocarbons of the C₂H₂ series, and gaseous Fe-group compounds are poisonous to Cu oxide catalysts but have less effect on Zn oxide catalysts.  A special catalyst operating at 230° and 100 atm. has been in use over a month with but slight decrease in CH₃OH yield.  The gas is obtained directly from a gas generator with coal as a raw material.
