Claim Text:
1. A process for conducting a Fischer-Tropsch reaction, comprising: flowing a reactant mixture in a microchannel reactor in contact with a catalyst to form a product comprising at least one higher molecular weight hydrocarbon product, the microchannel reactor comprising at least one process microchannel and at least one heat exchange channel in thermal contact with the at least one process microchannel, the catalyst being in the at least one process microchannel, the at least one heat exchange channel having a heat exchange fluid in it for exchanging heat with the at least one process microchannel; wherein the product further comprises tail gas, at least part of the tail gas being separated from the higher molecular weight hydrocarbon product and combined with fresh synthesis gas to form the reactant mixture, the volumetric ratio of the fresh synthesis gas to the tail gas in the reactant mixture being in the range from about 1:1 to about 10:1; the reactant mixture comprising H wherein the conversion of CO from the fresh synthesis gas in the reactant mixture is in the range from about 88% to about 95%, and the deactivation rate of the catalyst is less than about 1.4% per day; and the selectivity to methane in the product is in the range from about 0.01 to 10%.
