Epoxidation catalyst and process |
| abstract |
This invention relates to an ethylene oxide catalyst which contains silver and one or more alkali metal promoters supported on a carrier having a crush strength of at least 2.3 kg and a settled packing density of at least about 0.48 kg/litre which comprises first and second alpha alumina components with a first alpha alumina component in the form of particles having a median crystallite size of from 0.4 to 4 µm providing from 95 % to 40 % of the total weight of alpha alumina in the carrier and a second alpha alumina component generated in situ by a sol-gel process and providing the balance of the alpha alumina in the carrier. Titanic is optionally added to the carrier. |
