Patent number: 8722565Abstract: A method for applying a washcoat suspension to a support structure. To provide coatings with largely uniform thickness starting from washcoat suspensions, the method uses a device (10) set up to produce, by means of a process gas (40), a fluid bed of support structures in which the support structures circulate elliptically or toroidally, the method comprising the steps of: a) charging the device (10) with support structures and producing a support-structure fluid bed by means of a process gas (40), wherein the support structures circulate in the fluid bed elliptically or toroidally, preferably toroidally; b) impregnating the support structures with a washcoat suspension by spraying the support structures circulating elliptically or toroidally in the fluid bed with the washcoat suspension; c) drying the support structures sprayed with the washcoat suspension; and d) optionally calcining the support structures loaded with the solids contents of the washcoat suspension.Type: GrantFiled: June 2, 2008Date of Patent: May 13, 2014Assignee: Sued-Chemie IP GmbH & Co.

Patent number: 7696368Abstract: 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.Type: GrantFiled: May 7, 2008Date of Patent: April 13, 2010Assignee: SD Lizenzverwertungsgesellschaft mbH & Co.
