Abstract: A catalyst composition and process for preparing it and for using it to enhance the selectivity to light (C2 to C3) olefins in a Fischer-Tropsch conversion of synthesis gas is disclosed. The catalyst composition is an iron-based catalyst on an yttria/zirconia support. In a Fischer-Tropsch reaction the selectivity to ethylene may be enhanced by at least 20 mole percent and to propylene by at least 4 mole percent, in comparison with use of an otherwise identical catalyst that is free of yttria, in an otherwise identical Fischer-Tropsch reaction.

Abstract: A feedstream comprising hydrogen and a gas selected from carbon monoxide, carbon dioxide, or a combination thereof is converted to a product mixture containing a combination of saturated and unsaturated two carbon atom and three carbon atom hydrocarbons via contact with a mixed catalyst comprising a mixed metal oxide catalyst selected from a copper oxide, copper oxide/zinc oxide, copper oxide/alumina, copper oxide/zinc oxide/alumina catalyst, a zinc oxide/chromium oxide catalyst, or a combination thereof, in admixture with a molecular sieve catalyst having a CHA, AEI, AEL, AFI, BEA, or DDR framework type, or a combination of such molecular sieves. Exemplary molecular sieve catalysts include SAPO-34, SAPO-18, SAPO-5, and Beta. Advantages include reduced production of C1 hydrocarbons, C4 and higher hydrocarbons, or both; long catalyst lifetimes; desirable conversions; and desirable proportions of C2 and C3 paraffins.

Abstract: A method and an integrated system for reducing CO2 emissions in industrial processes. The method and integrated system (100) capture carbon dioxide (CO2) gas from a first gas stream (104) with a chemical absorbent to produce a second gas stream (106) having a higher concentration of carbon monoxide (CO) gas and a lower concentration of CO2 gas as compared to first gas stream. The CO gas in the second gas stream is used to produce C5 to C20 hydrocarbons in an exothermic reaction (108) with hydrogen (H2) gas (138). At least a portion of the heat generated in the exothermic reaction is used to regenerate the chemical absorbent with the liberation of the CO2 gas (128) captured from the first gas stream. Heat captured during the exothermic reaction can, optionally, first be used to generate electricity, wherein the heat remaining after generating electricity is used to thermally regenerate the chemical absorbent.

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.
