Method for preparation of catalysts
Abstract
Abstract A METHOD OF THE PREPARATION OF A CATALYST COMPRISING THE SEQUESTRATION OF MICRONUTRIENT METAL IONS IN LIQUID TWO OR MORE METALS IN LOW CONCENTRATION OND ONE OR MORE PHOSPHATIC FERTILIZER SOLUTIONS IS FACILITATED BY INCORPORATING I NONMETALLIC REFRACTORY MATERIALS IN HIGH CONCENTRATIONS N WHICH COMPRISES SUPPORTING THE METALS ON A FRACTION OF THE SOLUTIONS A SYNERGISTIC COMBINATION OF CITRATE AND THE NONMETALLIC REFRACTORY MATERIAL, AND MIXING SAID FRACPOLYPHOSPHATE SALTS. TION WITH THE REMAINING NONMETALLIC REFRACTORY MATERIAL, WHEREBY THE OVERALL CATALYST AT REACTION CONDUCTIONS CONSISTS OF A PHYSICAL MIXTURE OF THE SUPPORTED METALLIC COMPONENT AND THE REMAINING NONOMETALLIC REFRACTORY MATERIAL. MORE PARTICULARLY, THE SUPPORTED METALLIC COMPONENT IS TREATED UNDER REDUCING CONDITIONS TO FORM AN ALLOY OF THE MATALS ON SAID FRACTION ON THE NONMETALLIC REFRACTORY MATERIAL. IN PREFFERED EMBODIMENTS THE SUPPORTED METALLIC COMPONENT OF THE CATALYST COMPRISES TWO METALS, ONE FROM GROUP VIII AND ONE FROM GROUP I-B. OR BOTH FROM GROUP VIII.
