  • Catalyst and method for the alkylation of hydroxyaromatic compounds
    Patent number: 7208438
    Abstract: A method of making a catalyst comprising mixing a metal oxide precursor and a pore former to form a metal oxide precursor mixture and calcining the metal oxide precursor mixture in the presence of a flowing gas having a flow rate to form the catalyst comprising metal oxide. The catalyst comprises a first distribution of pores having a median pore diameter of 10 to 50 angstroms and a second distribution of pores having a median pore diameter of 1 to 500 angstroms. The median pore diameter of the second distribution of pores is inversely related to the flow rate of the gas.
