  • Process for preparing a catalyst
    Patent number: 7790648
    Abstract: The invention relates to a process for preparing a catalyst. The process allows the delamination of layered crystals which are used as a starting material for a catalyst. The starting material is subsequently converted into an active portion of a catalyst with an increased dispersion resulting in a higher activity. Preferred delaminating agents are di-carboxylic acids and one particular example is citric acid. Preferably at least 0.75 wt %, more preferably at least 1.5 wt % of a delaminating agent is added to the catalyst starting material.
    Type: Grant
