20100041932 | PROCESS FOR CONVERTING AN OXYGENATED FEED TO HIGH OCTANE GASOLINE - A process of modifying a zeolite catalyst to produce a modified zeolite catalyst wherein the modified zeolite catalyst has blocked pore sites. An oxygenated feed is flowed over the modified zeolite catalyst, wherein the oxygenated feed comprises hydrocarbons, methanol and dimethyl ether or a mixture thereof. The hydrocarbons, methanol and dimethyl ether in the oxygenated feed react with the modified zeolite catalyst to produce cyclic hydrocarbons, wherein the cyclic hydrocarbons produced has less than 10% durene and a median carbon number is C8. | 02-18-2010 |
20110124751 | SULFIDED FISCHER-TROPSCH CATALYST - Methods and compositions relate to a Fischer-Tropsch catalyst utilized to convert syngas into paraffins. The catalyst includes a given amount of sulfur content from contact of a catalytic supported metal with sulfur. Subsequent activation of the catalyst prepares the catalyst to be used for conversion of the syngas. The sulfur content maintained in the catalyst after being activated influences selectivity to paraffins over olefins and oxygenates. | 05-26-2011 |
20110230572 | Water-Forming Hydrogenation Reactions Utilizing Enhanced Catalyst Supports and Methods of Use - Improved reaction efficiencies are achieved by the incorporation of enhanced hydrothermally stable catalyst supports in various water-forming hydrogenation reactions or reactions having water-containing feeds. Examples of water-forming hydrogenation reactions that may incorporate the enhanced hydrothermally stable catalyst supports include alcohol synthesis reactions, dehydration reactions, hydrodeoxygenation reactions, methanation reactions, catalytic combustion reaction, hydrocondensation reactions, and sulfur dioxide hydrogenation reactions. Advantages of the methods disclosed herein include an improved resistance of the catalyst support to water poisoning and a consequent lower rate of catalyst attrition and deactivation due to hydrothermal instability. Accordingly, higher efficiencies and yields may be achieved by extension of the enhanced catalyst supports to one or more of the aforementioned reactions. | 09-22-2011 |
20120238647 | Methanation Reaction Methods Utilizing Enhanced Catalyst Formulations and Methods of Preparing Enhanced Methanation Catalysts - Enhanced mixed metal catalysts are provided which allow high conversions of carbon dioxide to methane, in some cases up to about 100% conversion. Methods of preparing enhanced mixed metal catalysts comprise a series of steps involving combining nickel and chromium salts with a nucleation promoter in a base environment to form a gel, allowing the gel to digest to form a solid and a mother liquor, isolating the solid, washing the solid, drying the solid, and thermally treating the solid to form a nickel-chromium catalyst. Methanation processes using the catalysts are also provided. The enhanced mixed metal catalysts provide more efficient conversion and lower operating temperatures for carbon dioxide methanation when compared to conventional methanation catalysts. Additionally, these enhanced catalyst formulations allow realization of higher value product from captured carbon dioxide. | 09-20-2012 |

20130116345 | LOW TEMPERATURE SULFUR TOLERANT TAR REMOVAL WITH CONCOMITANT SYNTHESIS GAS CONDITIONING - A catalyst comprising NiO, a metal mixture comprising at least one of MoO3 or WO3, a mixture comprising at least one of SiO | 05-09-2013 |
20130172650 | UPGRADING LIGHT OLEFINS - Methods and systems relate to upgrading light olefins, such as ethylene, propylene and butylenes, diluted in a gas mixture, such as refinery fuel gas. The upgrading yields products in a gasoline, distillate, lube oil or wax range without requiring purification or compression of the gas mixture prior to feeding the gas mixture to a reactor. In operation, the mixture contacts a solid oligomerization catalyst, such as silica supported chromium, within the reactor. This contact occurs at a first temperature suitable to produce oligomers that are formed of the olefins and adsorb on the catalyst in liquid or solid phases. Next, heating the catalyst to a second temperature higher the first temperature desorbs the oligomers that are recovered and separated into the products. | 07-04-2013 |
