铜基催化剂及其制备方法和使用该催化剂制备乙二醇的方法
摘要：
本发明涉及一种铜基催化剂，该催化剂包含载体和负载在该载体上的铜活性成分，其中所述载体为SiO2/Al2O3摩尔比≥3000的微孔分子筛。本发明还涉及所述催化剂的制备和使用该催化剂由DMO加氢制备EG的方法。通过选用前述微孔高硅分子筛作为催化剂的载体，当该催化剂用于催化DMO加氢制备EG时，可以将1,2-BDO的选择性控制得非常低，通常低至0.2％以内，同时还能保持高的DMO转化率和高的EG选择性。
摘要（英）：

Provided is a copper-based catalyst. The catalyst comprises a carrier and a copper active ingredient supported on the carrier, wherein the carrier is a microporous molecular sieve of which the molar ratio of SiO2/Al2O3 is ≥ 3000. Also provided is a method for preparing the catalyst, and a method for preparing EG from DMO using the catalyst by means of hydrogenation. By selecting the microporous high silicon molecular sieve as a carrier of a catalyst, when the catalyst is used in the preparation of EG by catalyzing DMO by means of hydrogenation, the selectivity of 1,2-BDO can be controlled to be very low, usually as low as 0.2% or less, and at the same time, a high conversion rate of DMO and a high selectivity of EG can also be maintained.
