- Abstract
In order to promote the dispersion of Cu species in the catalyst, oxalic acid, formic acid, and citric acid were added to the metal nitrates, and Cu/ZnO/In2O3 catalysts were synthesized by solid-state grinding. The results showed that the addition of oxalic acid had the best dispersion effect on Cu, and a maximum methanol yield of 2.1 mmol·gcat-1·h-1 was obtained at 280 ℃, 2 MPa, 3.6 L·gcat-1·h-1, V(H2)∶V(CO2)= 3∶1. However, formic acid decomposed into CO2 and H2 at high temperatures, leading to partial reduction of the CuO/ZnO/In2O3 catalyst, followed by over-reduction after H2 pretreatment, forming Cu3In7 alloy phase, thereby reducing the methanol yield.
