| titleOfInvention | Method for preparing cyclopentene by selective hydrogenation of cyclopentadiene |
| abstract | The invention provides a method for preparing cyclopentene by selective hydrogenation of cyclopentadiene, which comprises the following steps: filling a nickel-copper-based catalyst into a reactor, introducing hydrogen to carry out reduction treatment on the nickel-copper-based catalyst, introducing a liquid-phase diluent and a regulator to carry out stable treatment on the nickel-copper-based catalyst after the reduction treatment, mixing cyclopentadiene, hydrogen, the liquid-phase diluent and the regulator in the presence of the nickel-copper-based catalyst after the reduction treatment and the stable treatment, and introducing into the reactor to carry out selective hydrogenation reaction to prepare cyclopentene; wherein the regulator is carbon monoxide; the method of the invention can remove the reaction heat in time, improve the selectivity, prepare cyclopentene with high selectivity, and has the advantages of high activity, good stability, prolonged service life, and resistance to poisoning of impurities such as sulfur, arsenic, etc. |
