Disclosed are compounds of Formula : wherein: R1 is \u2014CH2CH2CF3; R2 is \u2014CH2CH2CF3, or \u2014CH2CH2CH2CF3; R3 is \u2014CH2CF3, \u2014CH2CN, \u2014CH2, pyridinyl, chloropyridinyl, or tetrahydropyranyl; Ring A is phenyl or pyridinyl; Ra, Rb, y, and z are defined herein. The powder is retained at the septum end of the container by the movable plug, which is displaced and pushed back as the solvent used for reconstituting the powder is introduced. After performing Fischer-Tropsch synthesis, the remaining hydrogen is separated from a hydrocarbon-rich stream using a hydrogen-permeable membrane, and the hydrocarbon-rich stream is returned to be subjected to steam reforming. The first gear train transmits power from the input shaft to the output shaft.
