Versuchsvorschrift

Catalyst preparation. A zirconium phosphate based catalyst was prepared by a co-precipitation method. A solution of zirconium hydroxide (Zr(OH)4) as a zirconium precursor was dissolved in deionized water. To this solution, a stoichiometric amount of phosphoric acid as a phosphorus precursor was added. The resulting mixture was heated at 80° C. for 2 hours to remove water, and a paste was obtained. The resulting paste was then dried in an oven at 100° C. overnight (about 12-18 hours) to remove the bulk of any remaining water, and to provide a powder. The powder was then calcined at 350° C. for 2 hours to obtain powdered zirconium phosphate.
