The coexistence of acid and basic sites promoted the selective transformation of ethanol into valuable products. Thus, MgO catalyst promoted the Guerbet reaction obtaining n-butanol as product while the incorporation of La2O3 in the catalytic system improved the ethanol conversion notably, obtaining ethylene as the main product due to a dehydration reaction. The highest ethylene yield was obtained for the catalyst with a Mg/La molar ratio of 1.Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)EthanolEthyleneAcetaldehydeButanolGas-phaseHeterogenous catalystArtículo10.1016/j.cattod.2023.114470Abierto
