Intrinsic kinetics of direct oxidative carbonylation of vapour phase methanol to dimethyl carbonate over Cu-based catalysts

In this paper, the process of direct oxidative carbonylation of vapour phase methanol to dimethyl carbonate (DMC) is investigated. The impregnation method is recommended to prepare the catalyst using CuCl 2 as precursor. Activated carbon AC1 is employed as support and heteropolyacid (HPA) as promote...

Description
Summary:In this paper, the process of direct oxidative carbonylation of vapour phase methanol to dimethyl carbonate (DMC) is investigated. The impregnation method is recommended to prepare the catalyst using CuCl 2 as precursor. Activated carbon AC1 is employed as support and heteropolyacid (HPA) as promoter or as the second support. The direct oxidative carbonylation of vapour phase methanol to DMC is a very complex reaction accompanied by by-products. By means of a modified Gauss–Newton method, an intrinsic double-rate kinetic model has been obtained. Residue analysis and variance tests show that the model is adequate.
