    摘要： Burner assembly comprising (a) an elongated body having a periphery, a discharge end adjacent a combustion zone, and an axis, wherein the axis extends into the combustion zone; (b) one or more oxidant nozzles disposed at the discharge end of the elongated body and adapted to discharge a gaseous oxidant into the combustion zone; and (c) one or more fuel nozzles disposed at the discharge end of the elongated body and adapted to discharge a fuel into the combustion zone. At least one of the oxidant and fuel nozzles is characterized by a shape factor, σ, that is greater than about 10, wherein σ is a dimensionless parameter defined as σ=P2/2A where P is the perimeter dimension of the discharge opening and A is the area of the discharge opening.

    摘要： The present invention provides a method for recovering a natural gas contaminated with high levels of carbon dioxide. A gas containing methane and carbon dioxide is extracted from a reservoir containing natural gas, where carbon dioxide comprises greater than 40 vol. % of the extracted gas. The extracted gas is scrubbed with a wash effective to produce a washed extracted gas containing less carbon dioxide than the extracted gas and at least 20 vol. % carbon dioxide. The washed extracted gas is oxidized with an oxygen containing gas in the presence of a partial oxidation catalyst to produce an oxidation product gas containing hydrogen, carbon monoxide, and carbon dioxide. The oxidation product gas is then utilized to produce a liquid methanol product.

    摘要： The present invention relates to a process for generating electricity with a solid oxide fuel cell system. First and second gas streams containing hydrogen are fed at independently selected rates to an anode of a solid oxide fuel cell. The first and second gas streams are mixed with an oxidant at one or more anode electrodes of the solid oxide fuel cell to generate electricity. An anode exhaust stream comprising hydrogen and water is separated from the anode of the fuel cell, and the second gas stream comprising hydrogen is separated from the anode exhaust stream and fed back to the anode of the fuel cell. The rates that the first and second gas streams are fed to the fuel cell are selected so the fuel cell generates a high electrical power density.
