标 题 :Process for the synthesis of methanol with optimised syngas preparation and processing
发明人：YIU KAR CHI
权利人:JOHNSON MATTHEY DAVY TECHNOLOGIES LTD
摘要:A process for synthesising methanol is described comprising the steps of (i) reforming a hydrocarbon feedstock in a hydrocarbon reforming unit comprising a fired heater and an autothermal reformer in series to form a synthesis gas containing hydrogen, carbon monoxide and carbon dioxide; (ii) dividing the synthesis gas into a first portion and a second portion, (iii) converting the first portion of synthesis gas into a methanol product in a methanol synthesis unit comprising one or more methanol synthesis reactors; and (iv) recovering a purge gas stream from the methanol synthesis unit, wherein the second portion of synthesis gas is passed to a hydrogen production unit where it is subjected to one or more stages of water gas shift in a water-gas shift unit to form a hydrogen-enriched gas, the a hydrogen-enriched gas is subjected to a step of carbon dioxide removal in a carbon dioxide removal unit to form a hydrogen product stream and a carbon dioxide stream, the carbon dioxide stream is recovered and at least a portion of the hydrogen product stream is fed to the fired heater as a fuel.

标 题 :Solid state combustion synthesis of nano to macroscale portland cement and other high value nano particles
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.
