| titleOfInvention | A kind of selection front-end hydrogenation method of alkynes and/or alkadienes in carbon two, C3 fraction |
| abstract | The invention provides the selection front-end hydrogenation method of alkynes in a kind of carbon two, C3 fraction and/or alkadienes, this method includes, the cracking gas logistics for coming from predepropanization tower or the outflow of front-end deethanization column overhead is mixed with the hydrogen-rich stream containing carbon monoxide, obtain the stable mixing hydrogen-rich cracking gas logistics of carbon monoxide content, then with palladium supported selective hydrogenation catalyst haptoreaction.Front-end hydrogenation method provided by the invention can be effectively prevented from carbon monoxide fluctuation in the cracking gas as caused by preceding system and caused by hydrogenation reactor temperature runaway and leakage alkynes.Under conditions of high-speed, method provided by the invention can effectively improve catalyst activity and selectivity, save catalyst activity component dosage. |
