The utilization of bio-ethanol for production of 1-butanol catalysed by Mg-Al mixed metal oxides enhanced by Cu or Co
Original language description
The Guerbet reaction is a possible way for transformation of ethanol to 1-butanol (important for many kinds of industries), which consists of four steps: dehydrogenation, aldol condensation, dehydration, and hydrogenation. Due to the elimination of possible side-reactions, the selective catalysis is required to favour production of 1- butanol at temperature below 350 degrees C. The main aim of this work was the ethanol transformation via heterogeneous catalysis using active Mg-Al mixed oxides with copper or cobalt carried out in the microflow reactor in the reaction temperature interval 280-350 degrees C. The novelty lies in the statistical analysis of results from characterization of catalyst structure and surface with catalysis results providing more sophisticated perspective on the ethanol valorization. The series of Mg-Al catalysts containing copper showed an overall higher conversion of ethanol and selectivity to butanol compared to the series containing cobalt. Major difference of catalytic activity was at low reaction temperatures and at a lower copper content in the Mg- Al matrix, which is significant from the point of view of environmentally clean processes. A multi-step mechanism of the Guerbet reaction involving an aldol condensation was verified for both tested catalysts series and reaction conditions.
