Abstract
A catalyst particle which comprises a metallic oxide such as kaolin is provided with the unique structure by mixing small amounts of a polyphosphate structuring agent with the metallic oxide and heating the mixture of metallic oxide and polyphosphate to allow reaction of the structuring agent with the metallic oxide.
Claims21
A catalyst particle comprising 1) a matrix comprising a modified metallic oxide, wherein a structuring agent comprising fertilizer grade ammonium polyphosphate mixes with a metallic oxide having a first crystalline phase, and said polyphosphate modifies said metallic oxide through heating and said modified metallic oxide is in a second crystalline phase;
- 2) zeolite or zeolite precursor, wherein said catalyst particle has a diameter of about 20 to 200 microns, and when zeolite precursor is present, zeolite is formed from said precursor.
