WebInterestingly, it is found that introducing TMA + into H-MOR zeolites significantly improves the catalytic activity and stability in DME carbonylation reaction as a result of depressing the methanol-to-hydrocarbons reactions. The 3TMA-H-MOR catalyst shows high stability for 210 hours on stream. WebDimethyl carbonate (DMC) has considerable potential as both a chemical intermediate and a fuel additive [1]. It can also be used as a precursor for carbonic acid derivatives and as a methylating agent [2]. Because of its high oxygen con-tent, DMC has been proposed as a replacement for methyl tert-butyl ether (MTBE) as a fuel additive[1]. DMC is ...
