Oxidation process null to the ethylene oxide of the catalytic converter and the ethylene which preparation it is processed and are prepared of the catalytic converter for ethylene oxide generation

摘要

This invention although from ethylene and oxygen ethylene oxide is formed in the vapor phase, regards the improvement process which manufactures the useful silver catalyst. The inactive carrier impregnation is done with the silver content chemical compound of the quantity which catalyst is effective, the alkaline metal content chemical compound of the promotion quantity, and the transition metal content chemical compound of the promotion quantity. Calcining by at temperature of approximately 200 - approximately 600 the carrier which this impregnation is done heating, as it converts the silver in silver content chemical compound to metal silver, disassembling all organic materials substantially, it removes. Heating is done under the atmosphere which includes the combination with the inert gas and the gas of approximately 10ppm - approximately 5% oxygen content oxidation component at capacity.
