FORSTADIUM TIL METANOLSYNTESEKATALYSATOR INDEHOLDENDE KOBBEROKSYD OG FREMGANGSMAADE TIL DETS FREMSTILLING

摘要

A methanol synthesis catalyst precursor comprises copper oxide and a support comprising spinel-forming metal oxides, spinel being present in crystallites not larger than 120 Angstrom units. Using catalyst prepared from such a precursor by reduction, methanol synthesis can be operated without catalyst changing for longer periods than when using a similar catalyst containing no spinel. A precipitation method for making the precursor is described.
