Abstract: The invention relates to a process for preparing methylamines by gas-phase reaction of methanol and ammonia as starting materials at a pressure in the range from 15 to 30 bar in the presence of heterogeneous catalyst. The starting materials are vaporized in one or more heat exchangers (1, 2, 3), superheated to produce a feed gas stream and subsequently fed into a reactor (4), with the mixing of the starting materials being able to be carried out in the feed stream to one of the heat exchangers (1, 2, 3) or at any desired position in a heat exchanger (1, 2, 3). A product gas stream comprising monomethylamine, dimethylamine and trimethylamine and also reaction by-products is taken off from the reactor (4). To control the reactor inlet temperature of the starting materials to a temperature in the range from 360° C. to 370° C., all or some of the feed gas stream or the product gas stream is passed through an adjustable valve (5) in order to vary the pressure and thus the condensation temperature.

Abstract: Producing porous catalyst pellets comprising rhenium on a support comprises preparing a mixture comprising the support and a pore-forming material (I), forming pellets from the mixture and simultaneously or subsequently removing (I) by heat treatment. The rhenium is predeposited on the support and/or added to the mixture and/or deposited on the pellets after heat treatment. Independent claims are also included for: (1) porous catalyst pellets produced as above; (2) metathesis of olefinic or acetylenic compounds by contact with porous catalyst pellets as above at 50-500[deg]C.
