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： A method for the preparation of a carbon molecular sieve capable of separating acid gases and fluorocarbons of the formula C.sub.a H.sub.b X.sub.c F.sub.d, wherein a is from 1 to about 6, b is from 0 to about 13, c is from 0 to about 13, d is from 1 to about 14, and X is a halogen; on the basis of shape selectivity and size exclusion. A precursor resin is heated at about 0.2.degree. C. per minute to about 500.degree. C. Then the resin is soaked at about 500.degree. C. for about 6 hours in flowing inert gas.
