Abstract
A process is disclosed for selectively producing 2-butanol from GVL by using at least one transition metal catalyst selected from the group consisting of iron, ruthenium, cobalt, rhodium and iridium.
Claims20
A process for selective production of 2-butanol from γ-valerolactone (GVL), the process comprising:
- a. providing in a reactor at least one transition metal catalyst selected from a group consisting of iron, ruthenium, cobalt, rhodium and iridium;
- b. heating a feedstock containing GVL, thereby forming a heated GVL feedstock;
- c. forming a reaction mixture by feeding into the reactor:
- i. the heated GVL feedstock;
- and
- ii. hydrogen gas;
- and
- d. maintaining a temperature of the reaction mixture in a range of 200−300° C. to allow selective production of reaction products containing 2-butanol,
- wherein no water is fed into the reactor during the process.
6 more elements
A method comprising:
- applying a catalyst containing at least one transition metal selected from a group consisting of iron, ruthenium, cobalt, rhodium and iridium, in a selective production of 2-butanol from GVL, wherein no water is fed into the method during the selective production of 2-butanol from GVL.
