Abstract
Methods for discovering optimum catalysts and/or reaction conditions for performing endo-or exothermic reactions, in particular gas-to-liquid reactions, are disclosed. A combinatorial approach is used to identify optimum catalysts and/or reaction conditions for performing the reactions. The reactions are performed in the channels of a microchannel reactor. These results can be used directly to optimize large scale reactions performed in a plurality of microchannel reactors, or can be correlated to useful catalysts and reaction conditions for use in large scale reactors by taking into consideration the heat transfer effects in the microchannel reactor and the large scale reactor. The method can advantageously be used to generate a database of combinations of catalyst systems and/or reaction conditions which provide various product streams, such that as market conditions vary and/or product requirements change, conditions suitable for forming desired products can be identified with little or no downtime. The catalysts can be evaluated using varied reaction conditions, which can provide a) a combinatorial library of product streams and a database including the combination of catalysts and reaction conditions to provide each product stream and/or b) the optimum combination of catalysts and reaction conditions for obtaining a desired product stream.
