  • Methanol production in a paraffinic medium
    Patent number: 4031123
    Abstract: Methanol is prepared from a feed gas containing carbon oxides and hydrogen by passing the feed gas through a catalyst bed in contact with an inert hydrocarbon liquid of the paraffinic or cycloparaffinic type under reaction conditions such that the equivalent methanol concentration in the liquid medium (corrected to 250.degree. C and 1000 psig) does not exceed 1.0 wt. %. The use of paraffinics and cycloparaffinics has significant advantages in reactor productivity over the use of other inert hydrocarbon liquids such as aromatics.
