Abstract: Form liquid product stream that has a C13 to C20 hydrocarbon content of less than 5.0 wt % based upon a total weight of the liquid product stream via a process that includes contacting synthesis gas with a sulfurized Zeolite Socony Mobil-5 catalyst. The sulfurized Zeolite Socony Mobil-5 catalyst can include ZSM-5, cobalt, an alkali metal, sulfur, and a reduction promoter.

Abstract: Preparation of a catalyst suitable for use in Fischer-Tropsch Synthesis reactions using a two step process in which the steps may be performed in either order. In step a), impregnate an iron carboxylate metal organic framework selected from a group consisting of iron-1,3,5-benzenetricarboxylate (Fe-(BTC), Basolite™ F-300 and/or MIL-100 (Fe)), iron-1,4 benzenedicarboxylate (MIL-101(Fe)), iron fumarate (MIL-88 A (Fe)), iron-1,4 benzenedicarboxylate (MIL-53 (Fe)), iron-1,4 benzenedicarboxylate (MIL-68 (Fe)) or iron azobenzenetetracarboxylate (MIL-127 (Fe)) with a solution of a promoter element selected from alkali metals and alkaline earth metals. In step b) thermally decompose the iron carboxylate metal organic framework under an inert gaseous atmosphere to yield a catalyst that is a porous carbon matrix having embedded therein a plurality of discrete aliquots of iron carbide. If desired, add a step intermediate between steps a) and b) or preceding step b) wherein the metal organic framework is impregnated with an oxygenated solvent solution of a polymerizable additional carbon source and the polymerizable additional carbon source is thereafter polymerized.

Abstract: A Fischer-Tropsch catalyst, useful for conversion of synthesis gas to olefins, is prepared from a catalyst precursor composition including iron oxide and an alkali metal on a substantially inert support, and then treated by a process including as ordered steps (1) reduction in a hydrogen-containing atmosphere at a pressure of 0.1 to 1 M Pa and a temperature from 280° C. to 450° C.; (2) carburization in a carbon monoxide-containing atmosphere at a pressure from 0.1 to 1 M Pa and a temperature from 200° C. to less than 340° C.; and (3) conditioning in a hydrogen- and carbon monoxide-containing atmosphere at a pressure from 0.1 to 2 MPa and a temperature from 280° C. to 340° C. The resulting catalyst exhibits at least one improvement selected from (1) increased overall activity; (2) reduced break-in time; (3) slowed rate of deactivation; and (4) increased time to onset of deactivation; when compared to an otherwise identical catalyst precursor composition treated by one or some, but not all, of the given steps and/or under different conditions.
