| titleOfInvention | Start-up of high selectivity catalysts in olefin oxide plants |
| abstract | A method to achieve a controlled start-up temperature of an expoxidation process which exceeds the maximum achievable temperature of the epoxidation reactor relative to using an external heat source. The method of the present invention employs an oxidation reaction within the reactor to bring the temperature of the reactor to a temperature that is suitable for conditioning a high selectivity catalyst. The method of the present invention includes first bringing a reactor including a high selectivity catalyst to a first temperature using the external heat source to the reactor, while staying within the reactor design limitations and maintaining a gas flow to the reactor that is within 25 to 100% of the design rates. Once the reactor has achieved the first temperature, at least an olefin, e.g., ethylene, and then oxygen are introduced to the reactor feed gas. The olefin and oxygen concentrations are adjusted to have a heat of reaction that will allow raising the reactor gas flow to 100% of design and then have sufficient heat of reaction to raise the reactor temperature to a second temperature which is greater than the first temperature and greater than the temperature of the reactor achievable by the external heat source. |
