20090158660 | Process to Maximize Methane Content in Natural Gas Stream - The present invention relates to a hydrogenolysis process and catalyst for conversion of ethane to methane in a natural gas stream when such streams contain large quantities of ethane. Such natural gas streams include the product of the in situ treatment of oil shale to produce oil and gas. Hydrogenolysis catalysts have been identified that produce high yields of ethane at low light-off temperatures. | 06-25-2009 |
20090209406 | Enhancement of Molecular Sieve Performance - A catalyst for converting methanol to light olefins and the process for making and using the catalyst are disclosed and claimed. SAPO-34 is a specific catalyst that benefits from its preparation in accordance with this invention. A seed material is used in making the catalyst that has a higher content of the EL metal than is found in the principal part of the catalyst. The molecular sieve has predominantly a roughly rectangular parallelepiped morphology crystal structure with a lower fault density and a better selectivity for light olefins. | 08-20-2009 |

20100078172 | Oil Recovery by In-Situ Cracking and Hydrogenation - Enhanced recovery of crude oil from an oil well is provided by in-situ cracking of an oxygenated organic compound to form hydrogen. The crude oil is then hydrogenated and hydrogenation reaction products and crude oil are recovered from the oil well. | 04-01-2010 |
20100081564 | PROTECTION OF SOLID ACID CATALYSTS FROM DAMAGE BY VOLATILE SPECIES - The invention provides a method to avoid catalyst damage and achieve longer catalyst life by selecting appropriate materials for reactor spacers, liners, catalyst binders, and supports, in particular, by not using crystalline silica-containing and high phosphorus-containing materials, if the presence of even small amount of steam is anticipated. In addition, alkali metals and alkaline earth metals are avoided due to potential damage to the catalyst. | 04-01-2010 |
20110027141 | Aromatics Co-Production in a Methanol-to-Propylene Unit - The present invention provides a reactor system having: (1) a first reactor receiving an oxygenate component and a hydrocarbon component and capable of converting the oxygenate component into a light olefin and the hydrocarbon component into alkyl aromatic compounds; (2) a separator system for providing a first product stream containing a C | 02-03-2011 |

20110245569 | Conversion of Acyclic Symmetrical Olefins to Higher and Lower Carbon Number Olefin Products - Processes for the conversion, under conditions and with a catalyst system effective for olefin metathesis, of hydrocarbon feedstocks comprising an acyclic symmetrical olefin (e.g., butene-2) are described. Olefin products of lower and higher carbon numbers (e.g., propylene and pentene) are formed in the presence of a catalyst comprising a solid support and a tungsten hydride bonded to alumina present in the support. This occurs despite the olefin metathesis reaction mechanism leading to a degenerative result, without any expected production of different carbon number products from acyclic symmetrical olefins. | 10-06-2011 |
20110245570 | Conversion of Butylene to Propylene Under Olefin Metathesis Conditions - Processes for the conversion, under conditions and with a catalyst system effective for olefin metathesis, of hydrocarbon feedstocks comprising butylene, for example all or a large proportion of a single C | 10-06-2011 |
20140058149 | HIGH EFFICIENCY PROCESSES FOR OLEFINS, ALKYNES, AND HYDROGEN CO-PRODUCTION FROM LIGHT HYDROCARBONS SUCH AS METHANE - High efficiency processes for producing olefins, alkynes, and hydrogen co-production from light hydrocarbons are disclosed. In one version, the method includes the steps of combusting hydrogen and oxygen in a combustion zone of a pyrolytic reactor to create a combustion gas stream, transitioning a velocity of the combustion gas stream from subsonic to supersonic in an expansion zone of the pyrolytic reactor, injecting a light hydrocarbon into the supersonic combustion gas stream to create a mixed stream including the light hydrocarbon, transitioning the velocity of the mixed stream from supersonic to subsonic in a reaction zone of the pyrolytic reactor to produce acetylene, and catalytically hydrogenating the acetylene in a hydrogenation zone to produce ethylene. In certain embodiments, the carbon efficiency is improved using methanation techniques. | 02-27-2014 |
20140058157 | PROCESS FOR INCREASING A MOLE RATIO OF METHYL TO PHENYL - One exemplary embodiment can be a process for increasing a mole ratio of methyl to phenyl of one or more aromatic compounds in a feed. The process can include reacting an effective amount of one or more aromatic compounds and an effective amount of one or more aromatic methylating agents to form a product having a mole ratio of methyl to phenyl of at least about 0.1:1 greater than the feed. | 02-27-2014 |
