| 摘要 |
The present invention relates to a method for the production of ethylene glycol using a feedstock comprising an oxalate and a catalyst containing copper and/or a copper oxide, comprising contacting the feedstock with the catalyst in a reactor under the conditions of a temperature in the range from about 170 to about 270° C., a weight hourly space velocity of the oxalate in the range from about 0.2 to about 5 h-1, a molar ratio of hydrogen to the oxalate in the range from about 40:1 to about 200:1 and a reaction pressure in the range from about 1.5 to about 10 MPa, to produce an effluent containing ethylene glycol, in which the reactor is a tube-array reactor using partitioned heat exchange and adopting outer and inner tubes configured in a double-tube structure to facilitate the heat exchange of the catalyst. |
