Abstract:
The invention discloses a method for converting methane to higher order hydrocarbons. This method includes synthesizing ammonia from natural gas and nitrogen in the presence of a source of hydrogen. The ammonia is converted to nitrous oxide in the presence of a source of oxygen. Methane is coupled in the presence of the nitrous oxide to provide higher hydrocarbons. The invention also discloses a method of balancing reaction heat requirements in a process for converting methane to higher order hydrocarbons.
Abstract:
A composite photonic crystal comprising an inverse opal structure defining an ordered array of voids with a filler composition received within the voids. A property of the filler composition changes in response to a stimulus, such as a temperature change, thereby changing the band gap of radiation that is reflected by the composite photonic crystal.
Abstract:
Photovoltaic modules are disclosed. The photovoltaic module comprises a front transparency, a potting material deposited on at least a portion of the front transparency, electrically interconnected photovoltaic cells applied to the potting material and a topcoat deposited on at least a portion of the electrically interconnected photovoltaic cells. Methods of making photovoltaic modules are also disclosed.
Abstract:
Disclosed are infrared reflective coating compositions and cured coatings deposited on a substrate, as well as multi-component composite coating systems. The coating compositions include an infrared transparent pigment and an infrared reflective pigment.
Abstract:
There is provided a process for producing high-purity meta-xylene by converting a hydrocarbon feedstream comprising at least about 5 wt % ethylbenzene and at least about 20 wt % meta-xylene, over a single molecular sieve catalyst under ethylbenzene conversion conditions sufficient to provide a primary product stream depleted of more than 50% of the ethylbenzene present in the feedstream. The process can further comprise stripping benzene and/or toluene by-products from the primary product stream to provide a secondary product stream comprising at least about 75 wt % mixed ortho-xylene and meta-xylene; and splitting the secondary product stream by removing substantially all of the ortho-xylene present therein to provide a tertiary product stream comprising at least about 95 wt % meta-xylene.
Abstract:
There is provided a process for reacting a 2-arylethanol, such as 2-phenethanol, with an aromatic compound, such as toluene, to produce a 1,2-diarylethane, such as 2-phenethyltoluene. The reaction involves the use of a catalyst comprising an acidic solid oxide, such as ZSM-5, zeolite Beta, MCM-22 or ZSM-12.

Abstract:
Zeolites (e.g. ZSM-5 and zeolite beta) enriched with hydroxyl groups are prepared by ammonia treatment of sieves which have suffered loss of tetrahedral aluminum from framework positions followed by careful calcination (200.degree.-450.degree. C.). The hydroxyl group created by this method are stable only to 500.degree. C.
