    摘要: The present invention relates to an improved catalyst for the selective synthesis of monomethylamine (MMA) and dimethylamine (DMA) at the expense of trimethylamine (TMA) for a starting feed of methanol and/or dimethyl ether and ammonia. The current industrial catalyst for this process is a standard SiO.sub.2 /Al.sub.2 O.sub.3 material. The present invention combines this standard catalyst with microporous carbon molecular sieves (CMS) to form a composite material (i.e., a CMS/SiO.sub.2 /Al.sub.2 O.sub.3 material) with higher selectivity for the desired products MMA and DMA. The invention also relates to methods of making the improved catalyst and a process of using the improved catalyst material in the production of MMA and DMA.

    摘要: In the preparation of dimethyl ether by the catalytic dehydration of methanol, reaction rate is enhanced and catalyst coking and byproduct formation are significantly reduced when an aluminotitanate containing 0.1-20% of titania and 80-99.9% of alumina is used as the catalyst.
