while embodiments of the present invention operate effectively below about 250 psi to achieve the optimal desired product selectivity in this context u201c selectivity u201d refers to moles of referenced fuel product formed per mole of co converted in the preferred embodiment described herein the product is a diesel type fuel or diesel type fuel blendstock consisting of majority of c 8 c 24 hydrocarbons and a minimal amount of wax c 24 hereinafter the diesel fuel or diesel blendstock fraction that consists of hydrocarbons with a majority in the c 8 c 24 range is referred to as u201c diesel fuel u201d a process in accordance with the present invention described herein produces a diesel fuel and wax at a ratio of between about 5 1 and about 30 1 by weight the product produced directly from the application of this invention is a high cetane diesel fuel having a diesel fuel to wax ratio of greater than 5 to 1 by weight a traditional f t product has a product distribution where the ratio of diesel fuel to wax ratio is close to 1 1 contrary to the traditional f t product in embodiments of the invention the diesel fuel can be produced directly from syngas at high yields by passing the syngas through a f t reactor in a single pass without requiring hydrocracking or other additional processes in other embodiments unconverted syngas is recycled to the head of the reactor and blended with incoming feed gas the diesel fuel is liquid under ambient conditions e g.
