Latest Patents
Renner's latest patents focus on innovative silver catalysts and processes for their preparation. One of his patents describes a silver catalyst containing lithium and cesium as promoters for the direct oxidation of ethylene with oxygen to produce ethylene oxide. This catalyst is applied to a porous carrier, primarily consisting of α-alumina, and includes specific amounts of soluble calcium, aluminum, potassium, and sodium salts. The carrier features a BET surface area ranging from 0.4 to 0.8 m²/g, a pore volume of at least 0.45 ml/g, and a bulk density of less than 700 kg/m³. The design ensures that more than 13% by weight of silver is applied as the active component, with over 115 kg of silver available per m³ of reactor. Additionally, the patent outlines the preparation process for this silver catalyst and its application in ethylene oxidation.
Another patent by Renner details a similar silver catalyst for the direct oxidation of ethylene. This catalyst is also applied on a porous carrier, consisting of α-alumina, and contains various soluble salts. The carrier has a BET surface area of 0.2 to 0.8 m²/g, a pore volume of no less than 0.5 ml/g, and a bulk density of less than 650 kg/m³. The geometric surface area in the reactor is designed to be not less than 600 m²/m³, with more than 13% by weight of silver as the active component.
