The present application relates to an apparatus and process for producing dimethyl carbonate, in particular a system (apparatus or process) for DMC synthesis without the need of using a dehydrating agent. More particularly, the feed mixture for the process can be selected from the following options: a) carbon monoxide, methanol and flue gas from the process, b) synthesis gas without CO2 and flue gas from the process, c) synthesis gas with CO2 and added synthesis gas from purified flue gas from the process. The process uses a catalyst cluster comprising a specific combination of different groups of heterogeneous catalysts wherein each group has a different function. Also the invention relates to an apparatus comprising a specific combination of heterogeneous catalysts for applying different routes to produce dimethyl carbonate from each feed mixture option, on continuous basis.
Apparatus for producing dimethyl carbonate (DMC), comprising a DMC reactor for synthesizing DMC from a feed mixture at least comprising MeOH, CO2, and CO, wherein the DMC reactor comprises a mixture of at least two heterogeneous catalyst groups comprising catalysts C2 and C3, wherein catalyst C2 promotes the reaction of MeOH with CO2 to produce DMC and H2O as byproduct, and catalyst C3 promotes the transformation of CO and H2O to H2 and CO2.
Process for producing dimethyl carbonate (DMC), comprising the step of synthesizing DMC from a feed mixture at least consisting of MeOH, CO2, and CO by heterogeneous catalysts in a DMC reactor comprising a mixture of at least two heterogeneous catalyst groups comprising catalysts C2 and C3, wherein catalyst C2 promotes a reaction of MeOH with CO2 to produce DMC and H2O as byproduct, and catalyst C3 promotes the transformation of CO and H2O to H2 and CO2.
