Epoxidation process

A method is provided for improving the performance of a silver-based epoxidation catalyst comprising a carrier. The carrier includes at least 80 percent alpha alumina and has a pore volume from 0.3 ml/g to 1.2 ml/g, a surface area from 0.3 m2/g to 3.0 m2/g, and a pore architecture that provides at least one of a tortuosity of 7 or less, a constriction of 4 or less and a permeability of 30 mdarcys or greater. ... Scientific Design Company Inc

Epoxidation process

A method for the oxidation of ethylene to form ethylene oxide which comprises: providing an aqueous stream containing ethylene glycol and impurities; introducing the aqueous stream in a first ion exchange treatment bed to reduce the content of these impurities; determining whether an outlet of the first ion exchange treatment bed has a conductivity greater than about 5 μs/cm; upon determining that the outlet of the first ion exchange treatment bed has a conductivity greater than about 5 μs/cm, introducing the outlet of the first ion exchange treatment bed into a second ion exchange treatment bed; and upon determining that the outlet of the first ion exchange treatment bed has a conductivity greater than about 60 μs/cm, redirecting the introduction of the aqueous stream to the second ion exchange treatment bed and regenerating the first ion exchange bed.. . ... Scientific Design Company Inc

Glycol ether process

A process for the preparation of glycol ethers by providing a diethylene glycol ether column bottoms mixture comprising triethylene glycol ether, tetraethylene glycol ether, and glycol ether catalyst; separating, in a stripping column, the column bottom mixture into a triethylene glycol ether vapor overhead and a liquid bottoms; and separating, in an evaporator, the liquid bottoms into a residue containing about 80% to about 90% tetraethylene glycol ether and an evaporator overhead comprising at least about 60% tetraethylene glycol ether.. . ... Scientific Design Company Inc

Porous bodies with enhanced pore architecture

A porous body is provided with enhanced fluid transport properties that is capable of performing or facilitating separations, or performing reactions and/or providing areas for such separations or reactions to take place. The porous body includes at least 80 percent alpha alumina and has a pore volume from 0.3 ml/g to 1.2 ml/g and a surface area from 0.3 m2/g to 3.0 m2/g. ... Scientific Design Company Inc

Epoxidation process

A method for producing ethylene oxide comprising: a) providing one or more feed components, wherein the one or more feed components contains at least ethylene obtained by dehydrating ethanol; b) contacting the one or more feed components with an ethylene oxide catalyst bed disposed in a reactor tube, the ethylene oxide catalyst bed comprising: (1) an upstream ethylene oxide catalyst having a first cesium concentration and (2) a downstream ethylene oxide catalyst having a second cesium concentration, wherein the first cesium concentration is higher than the second cesium concentration.. . ... Scientific Design Company Inc

Carrier treatment to improve catalytic performance of an ethylene oxide catalyst

A method for lowering the sodium content of different carriers which may have different physical properties as well as varying degrees of sodium is provided. The method, which lowers the sodium content from the surface, subsurface as well as the binding layer of the carrier, includes contacting a carrier with water. ...
