The tableted catalyst support is an alpha-alumina catalyst support obtained with high geometrical precision and displaying a high overall pore volume, thus allowing for impregnation with a high amount of silver, while exhibiting a surface area sufficiently large so as to provide optimal dispersion of catalytically active species, in particular metal species.

The invention moreover relates to a compacted body obtained by tableting a free-flowing feed mixture which comprises, based on inorganic solids content, at least 50 wt.-% of a transition alumina having a loose bulk density of at most 600 g/L, a pore volume of at least 0.6 mL/g, as determined, and a median pore diameter of at least 15 nm. The invention moreover relates to a shaped catalyst body for producing ethylene oxide by gas-phase oxidation of ethylene, comprising at least 15 wt.-% of silver, relative to the total weight of the catalyst, deposited on the tableted alpha-alumina catalyst support.

Abstract: A method for producing a catalyst effective in the oxidative conversion of ethylene to ethylene oxide, the method comprising: (i) impregnating a porous refractory carrier with a sub-catalytic level of silver ion in a range of 0.1 wt% to 1 wt% of silver by weight of the carrier and silver, and at least partially reducing said silver ion to elemental silver to produce a low-silver catalyst precursor having isolated silver atoms or silver nanoparticles on surfaces of said refractory carrier; and (ii) further impregnating the low-silver catalyst precursor with a catalytic amount of silver ion of at least 10 wt% total amount of silver and at least one promoting species by weight of the carrier and silver, and subjecting the further impregnated carrier to an elevated temperature of at least 200C to completely reduce silver ion to elemental silver in the carrier. The low-silver catalyst precursor produced in step (i) is also described in detail. Methods for using the catalyst produced in step (ii) for the oxidative conversion of ethylene to ethylene oxide are also described.

Abstract: Disclosed herein are methods of using scaled selectivities to assist in determining whether changes to the value of a target ethylene oxide production parameter—such as ethylene oxide production rate—used in the process of epoxidizing ethylene with a high-selectivity catalyst, have caused the process to move away from optimal operation. If the deviation from optimal operation has not worsened, it is generally unnecessary to perform a full optimization study even if the value of a target ethylene oxide production parameter has changed, which reduces or eliminates process disturbances caused by carrying out such studies. Methods are also disclosed which use both scaled selectivities and scaled reaction temperatures. If scaled selectivities reveal that a change in the value of a target ethylene oxide production parameter has moved the process away from optimal operation, scaled reaction temperatures can, under certain conditions, provide an indication of the directions in which the reaction temperature and/or overall catalyst chloriding effectiveness should be changed to move toward optimal operation. If a change in the value of a target ethylene oxide production parameter has improved the scaled selectivity, the scaled reaction temperature may also be used to guide further adjustments which may further improve scaled selectivity.

Abstract: A silver-based ethylene oxide catalyst is provided that has enhanced stability. The enhanced stability is obtained in the present invention by providing a silver-based ethylene oxide catalyst that includes from 100 ppm to 1000 ppm of zinc, and from greater than 450 ppm to less than 800 ppm of cesium. Zinc and cesium are promoters that are introduced to a finished carrier either prior to, coincidentally with, or subsequent to the deposition of the silver. The silver-based ethylene oxide catalyst can be used in the epoxidation of ethylene to ethylene oxide.

Abstract: A novel process and apparatus is disclosed for performing chemical reactions. Highly compressed gaseous streams such as H2, CO, C02, H20, 02, or CH4 are raised to Mach speeds to form supersonic jets incorporating Shockwaves. Two or more such jets are physically collided together to form a localized reaction zone where the energy from the Shockwaves causes endothermic reactions wherein the chemical bonds of the reactant gases are broken. Between and among reactants molecular surface interaction and molecular surface chemistry take place. In the ensuing exothermic reactions a desired new chemical product is formed and this product is locked into a lower state of enthalpy (state of energy of formation) through adiabatic cooling by means of a free-jet expansion.
