摘要:A ruthenium-phosphine complex can be used as a catalyst in a method for the catalytic synthesis of urea. The method may comprise more particularly a reaction of formamide or of formamide with ammonia in the presence of the catalyst to form urea and hydrogen. Through the use of the ruthenium-phosphine complex as the catalyst, catalytic preparation of urea from formamide or from formamide with ammonia is provided for the first time. This allows for synthesis under mild conditions and virtually no formation of byproducts. Further, using an acid as a cocatalyst in the catalytic synthesis or the reaction can lead to an improvement in urea yield.

摘要:The present invention relates to a mesoporous cobalt-metal oxide catalyst for the Fischer-Tropsch synthesis and a method of preparing the same. The mesoporous cobalt-metal oxide catalyst for the Fischer-Tropsch synthesis of the present invention can very stably maintain the mesoporous structure even under a H2-rich high-temperature reduction condition and under a reaction condition of the low-temperature Fischer-Tropsch synthesis, easily transport reactants to the active site of the catalyst due to structural stability, and facilitate the release of heavier hydrocarbon products after production thereof. Additionally, unlike the conventional cobalt-based catalysts which are prepared by adding various co-catalysts for the purpose of improving reducibility, activity, selectivity and increasing thermal stability, etc., the mesoporous cobalt-metal oxide catalyst for the Fischer-Tropsch synthesis can constantly maintain conversion and selectivity at high levels without further requiring co-catalysts and thus it can be very effectively used for the Fischer-Tropsch synthesis.

发明人：KILAMBI SRINIVAS
权利人:KILAMBI SRINIVAS; SRIYA GREEN MATERIALS INC
摘要:A method of making Portland cement, white cement, calcium aluminates, calcium aluminum silicates and similar oxides using solid state combustion synthesis is described. The method uses less energy and produces lower CO 2 emissions than conventional processes. The method uses green fuels like biomass and lignin and eliminates most of the coal used in traditional cement production. A batch reactor and a semi-continuous reactor that can be used for the combustion synthesis are also described.

摘要:Described herein are catalyst support materials for use in synthesizing ammonia (NH 3 ) from nitrogen gas (N 2 ) and hydrogen gas (H 2 ) and methods of making the same. The support material may comprise (MgO) x (BaO) y (Al 2 O 3 ) z and/or (MgO) x (SrO) y (Al 2 O 3 ) z , on which an ammonia synthesis catalyst such as ruthenium is dispersed. When the catalyst support material comprises (MgO) x (BaO) y (Al 2 O 3 ) z , x is from about 0.05 to about 0.7, y is from about 0.05 to about 0.6, and z is from about 0.3 to about 0.5. When the catalyst support material comprises (MgO) x (SrO) y (Al 2 O 3 ) z , x is from about 0.4 to about 0.7, y is from about 0.05 to about 0.5, and z is from about 0.05 to about 0.3.
