Abstract:
本发明提供了一种高选择性γ‑戊内酯加氢制备1,4‑戊二醇和2‑甲基四氢呋喃的方法，具体来说以钙钛矿作为载体的负载型非贵金属Cu、Ni催化剂的制备和应用。本发明所述的催化剂可实现γ‑戊内酯高效催化加氢制备1,4‑戊二醇和2‑甲基四氢呋喃，反应可在连续、间歇釜式反应器以及连续固定床反应器中进行。催化剂具有高活性，高选择性及高稳定性，可以通过改变反应条件高选择性的调控目标产品，反应条件温和，工艺简单，具有良好的工业应用前景。
Abstract(English):

The invention provides a method for preparation of 1,4-pentanediol and 2-methyltetrahydrofuran by high-selectivity hydrogenation of gamma-valerolactone, specifically to preparation and application for a supported non-noble metal Cu/Ni catalyst by using perovskite as a carrier. The catalyst of the invention realizes preparation of 1,4-pentanediol and 2-methyltetrahydrofuran by catalytic hydrogenation of gamma-valerolactone with high efficiency, and the reaction is conducted in a continuous stirred tank reactora continuous batch reactor and a continuous fixed bed reactor. The catalyst has high activity, high selectivity and high stability, and the target products can be controlled with high selectivity by changing reaction conditions. The reaction conditions are mild, the process is simple, and the method has a good prospect of industrial application.
