| titleOfInvention | Start process of highly selective ethylene oxide catalyst |
| abstract | A process for starting ethylene epoxidation is provided. The process includes initiating an epoxidation reaction by reacting a feed gas composition in a presence of an epoxidation catalyst at a first temperature of from about 180 ° C to about 210 ° C. The first temperature was raised to a second temperature of about 230 ° C. to about 290 ° C. over about 6 hours to about 50 hours simultaneously with addition of a sufficient concentration of moderator, and adsorbed to the catalyst after reaching the second temperature. The amount of moderator is about 10 to about 50 g / m 3 with respect to the catalyst. A second temperature is maintained while adjusting the feed gas composition to include about 0.5% to about 25% CO 2 for about 50 hours to about 350 hours. The moderator concentration is increased to a level exceeding the sufficient concentration, and at the same time the second temperature is lowered to the third temperature. |
