Mixed MgAl Oxide Supported Potassium Promoted Molybdenum Sulfide as a Selective Catalyst for Higher Alcohol Synthesis from Syngas MoS2/K2CO3 on Mixed Metal Oxides for Higher Alcohol Synthesis

A Mg/Al mixed metal oxide material (MMO) is introduced as a support for K 2 CO 3 promoted MoS 2 in CO hydrogenation reactions at 310 °C and 1,500 psig. The catalyst is shown to be more selective for C 2 –C 4 linear alcohols (substantially so for C 3 –C 4 linear alcohols) than for methanol and offers...

Summary:A Mg/Al mixed metal oxide material (MMO) is introduced as a support for K 2 CO 3 promoted MoS 2 in CO hydrogenation reactions at 310 °C and 1,500 psig. The catalyst is shown to be more selective for C 2 –C 4 linear alcohols (substantially so for C 3 –C 4 linear alcohols) than for methanol and offers good alcohol to hydrocarbon selectivity. Methanol selectivity of the MMO supported catalyst deviates greatly from the Anderson–Shultz–Flory distribution. Graphical Abstract
