Abstract
In a process for the production of higher alcohols, i.e. Calcohols, from syngas, the syngas is first reacted in a heterogeneous alcohol pre-converter (A) using an alcohol synthesis catalyst, whereby methanol as the main product in a concentration corresponding to or close to the equilibrium concentration is produced. Then the effluent from the pre-converter is mixed with unconverted wet recycle gas and reacted in a heterogeneous reactor for higher alcohols synthesis (B) containing a higher alcohols synthesis catalyst, and finally the effluent from the reactor for higher alcohols synthesis is separated into (i) unconverted syngas, which is recycled to the higher alcohols synthesis reactor, (ii) methanol and light alcohols, which are recycled to the higher alcohols synthesis reactor, and (iii) the final product consisting of higher alcohols.
