Abstract
Methods for discovering optimum catalyst systems for the conversion of syngas to higher molecular weight products via Fischer-Tropsch synthesis are disclosed. A combinatorial approach is used to identify combinations of catalyst systems useful for performing the reactions. The combinations of catalyst systems include Fischer-Tropsch catalysts and olefin isomerization catalysts. The method can advantageously be used to generate a database of combinations of catalyst systems and/or reaction conditions that 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 are combined in a logical manner, for example in the form of arrays. The combinations of 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.
