Syngas Conversion over Perovskite-Like LaCuxTi1- xO3/KIT-6 Catalysts
Synthesis of alcohols from syngas is one of the methods used to produce biofuel. The use of methanol is the most efficient in internal combustion engines. Commercial methanol production is based on CuZn-containing catalysts. The promotion of copper catalysts with alkali or rare-earth metals makes it possible to increase the methanol yield or shift the distribution of products toward higher alcohols. High activity of copper-containing catalysts may be caused by the binding of the highly dispersed copper phase to the rare-earth oxide substrate, for example, in the perovskite structure. Earlier a considerable activity and selectivity in the methanol synthesis were demonstrated for massive perovskites of the LaCuxTi1-xO3 composition synthesized by the citrate method . Here we have studied the effects of the Cu/La, Cu/Ti ratios and the increase in the specific surface area by introducing template - KIT-6 mesoporous silica on the catalytic properties of the LaCuxTi1-xO3/KIT-6 system (x = 0.4÷0.8).
