Methods for converting syngas and to optimize the conversion of syngas into products of higher molecular weight.And to quickly determine an appropriate set of reaction conditions and combinations of catalyst to form a desired product. Methods for conversion of syngas into products of higher molecular weight using Fischer Tropsch synthesis, and methods for optimizing the systems of catalyst in the synthesis, are disclosed.In one method, the methods using Fischer Tropsch catalysts of ruthenium cobalt / in combination with a catalyst for isomerization of olefin.That isomeriza double bonds in olefin C ~ 4 ~ + as they are formed.In another method, the methods using Fischer Tropsch catalysts that may or may not be a catalyst of cobalt and ruthenium.In combination with catalysts for isomerization of olefin which are acidic enough to isomerizar olefins of C ~ 4 ~ + but not too acid to cause rapid coking.A benefit of using relatively less acidic zeolites is the reason of ISO paraffins to aromatics is increased when more acids on zeolites are used.Also, the relatively less acidic zeolites coqueificam not so easily that zeolites with more acid.The methods may advantageously be optimized using combinatorial chemistry, in which a database of combinations of catalyst systems and, optionally, reaction conditions.Providing multiple streams of product are generated.As the market conditions vary and / or the requirements of product change, the appropriate conditions to form the desired products can be identified with little or no downtime.
