This invention is related to the synthesis of organic carbonates from carbon dioxide and epoxides. It is particularly focused on the production of propylene cyclic carbonate from propylene oxide. The proposed catalytic materials includes a support made of aluminum oxyhydroxide (Catapal B&#xae;), nitric acid, acetic acid and/or phosphoric acid. An important stage is the physical and chemical conditioning of the catalytic materials and to this end, experimental methodologies such as spheronization and thermal treatments were implemented prior the evaluation process.

Catalytic formulation for producing propylene cyclic carbonate from carbon dioxide using a potassium iodide catalyst

The present disclosure is directed to a non-destructive process for removing metals, metal ions and metal oxides in alumina-based materials without destroying alumina, allowing the regeneration of alumina-based catalysts. The non-destructive process uses an extracting agent that sequesters metals, metal ions and/or metal oxides present in alumina-based materials without destroying the alumina, allowing the regeneration of alumina-based catalysts.

Non-destructive process for removing metals, metal ions and metal oxides from alumina-based materials

A method for eliminating silicon or silicon compounds in alumina based materials without destroying such alumina based materials enabling reutilization particularly in catalysts for hydrotreating processes, comprising: a) mixing alumina based solid material which contains silicon with an alcohol extraction agent at a temperature between 10 and 300&#xb0; C., for 10 minutes to 96 hours to form a mixture; b) separating solids from the mixture by centrifugation, decantation or filtration to obtain separated solids; c) washing the separated solids with at least one of water, alcohol or an ammonium hydroxide solution to form washed solids; and d) drying the washed solids to obtain regenerated alumina based solid material.
