Assignee:

Syntroleum Corporation - Tulsa OK

International Classification:

B01J 3502

US Classification:

422211, 422224

Abstract:

A Fischer-Tropsch catalyst for the conversion of synthesis gas into Fischer-Tropsch products includes a stationary Fischer-Tropsch catalyst having a voidage ratio greater than approximately 0. 45 or 0. 6 and may further have a catalyst concentration for a given reactor volume of at least 10 percent. A Fischer-Tropsch catalyst has a structured shape promoting non-Taylor flow and/or producing a productivity in the range of 200-4000 vol CO/vol. Catalyst/hour or greater over at least a 600 hour run of a Fischer-Tropsch reactor with the catalyst therein. A system for converting synthesis gas into longer-chain hydrocarbon products through the Fisher-Tropsch reaction has a reactor for receiving synthesis gas directly or as a saturated hydrocarbon liquid or a combination, and a stationary, structured Fischer-Tropsch catalyst disposed within the reactor for converting at least a portion of the synthesis gas into longer-chain hydrocarbons through Fischer-Tropsch reaction. A Fischer-Tropsch reactor system having a structured Fischer-Tropsch catalyst may have an all-liquid saturated reactant feed, an all gas reactant feed, or a plethora of combinations therebetween. The systems may or may not include heat removal devices.

International Classification:

B01J 2034

US Classification:

502 41

Abstract:

A process for regenerating a slurry Fischer-Tropsch catalyst, which needs regeneration, involves de-waxing and drying the catalyst sufficiently to produce a free-flowing catalyst powder that is fluidizable; fluidizing the catalyst powder; treating the catalyst powder with an oxygen treatment; reducing the catalyst powder with a reducing gas to form a reduced catalyst powder; and mixing the reduced catalyst powder with hydrocarbons to form a regenerated, slurry catalyst. The oxidation and reduction steps may be repeated. An oxygen treatment includes using a fixed O level with ramped temperatures, fixed temperatures with increased O levels, or a combination.

US Classification:

95 50, 95 51, 95 96, 95130, 95139

Abstract:

A process for the removal of inert gases, such as nitrogen and carbon dioxide, from methane-containing gases, such as natural gas, including a first stage removal which lowers the total combined inert content to about less than 30% and a second stage removal utilizing a pressure swing adsorption process comprising one or more adsorbent beds comprising contracted titanosilicate-1 adsorbent, wherein the purified methane-containing gas contains less than about 6% total combined inerts.

US Classification:

518/704000, 422/189000

Abstract:

A system and method for converting normally gaseous, light hydrocarbons into heavier, longer-chain hydrocarbons includes a turbine; a first synthesis gas subsystem; a second synthesis gas subsystem that receives thermal energy from the turbine and which preferably includes a steam reformer; and a synthesis subsystem for receiving synthesis gas from the first synthesis gas subsystem and the second synthesis gas subsystem and for producing the heavier hydrocarbons. A method includes using a plurality of synthesis gas subsystems to prepare synthesis gas for delivery to and conversion in a synthesis subsystem.

International Classification:

C07C027/06
B32B027/04

US Classification:

518/710000, 422/140000

Abstract:

The invention is directed to reactor systems, apparatus, and processes which are useful for conducting chemical reactions that may be effected in a three phase slurry system. One particular application of the invention converts synthesis gas (syngas) into hydrocarbons. Syngas is comprised of carbon monoxide and hydrogen. In general, a low profile bed reactor is capable of conducting an exothermic catalytic conversion. The reactor may also include a catalyst contained in a moving fluid system which ascends in the reactor in one or more stages. A heat exchanger optionally may be used to remove heat, and water may be removed from the reaction as it proceeds from one stage to another. The reactor is designed in a relatively low profile horizontal design, and is usually more efficient and inexpensive to operate (or build) than taller vertically oriented reactors of the same type.
