PROCESS FOR THE SELECTIVE PREPARATION OF 1-PROPANOL, ISO-BUTANOL AND OTHER C3+ ALCOHOLS FROM SYNTHESIS GAS AND METHANOL

摘要

Process for the preparation of a product alcohol mixture comprising the steps of : (a) providing a synthesis gas comprising carbon monoxide and hydrogen (b) providing an amount of methanol and a second source alcohol Rn-CH2-CH2-OH comprising n+2 carbon atoms (Rn=CnH2n+1, n=O) to the synthesis gas to obtain a selective alcohol synthesis mixture (c) converting the selective synthesis mixture in presence of one or more catalysts catalysing the conversion of the synthesis gas mixture into a product alcohol mixture in which the initially dominating alcohol is a preferred Cn+3 alcohol having the structure Rn-CH (CH3) -CH2-OH (d) withdrawing the product alcohol mixture of step (c).
